New to the scooters here. My son has a stock 2013 quattronove 50x, we are wanting to keep it stockish but would like to make it quicker than 50km/hr. Would this clutching do this or not?
For a year now, I've known how to change a belt and assemble a varitator. But I was in the dark with how it worked. I watched so many videos explaining it but your style of explaining how it works was super easy to understand. Thank you for making this video, keep going!
First explanation I’ve seen that completely and clearly describes what a variator is doing and how roller weight affects the rpm at which the pulley’s effective diameter changes as well as the rate at which that change takes place all else being equal. Excellent video! Subbed and liked.
This is how an instructional video is done - clear, to the point and you know what you’re talking about. The Americans just waffle on and on and on for ages and say very little. This is a breath of fresh air. I just subscribed . Thank you for doing this so well
@@elizabethmcheffey8699 Americas economy will collapse in your lifetime under the weight of 29 Trillion Dollars (and rising), you cant even afford the interest repayments on 29 trillion dollars, the ignorance of America is impressive. You could try to pray the problem away hehehe. The rest of the world knows this and is laughing at America. outside America, you are the butt of all jokes. Land of the fleeced home of the slave. good luck with that
Thank you for doing this video! I’m just learning as I go and everytime I ask another rider.. they always say it’s easy but never really explain it like the way you just did! Thank you again
Hey mate, thanks for the video. I watched a few and got more confused than I was when I started. Your video was very clear, mate. Thanks a lot I think I know what to do now actually. Cheers.
lighter rollers allows reduced load so energy to rotate is less and so rotation is quicker. Too light and the gearing will progress to slowly causing an over rev. It takes more energy to rotate the heavier rollers so the accelration is reduced. Top speed is created by optimising the roller weights.
Very good explanation on how a varaitor works with different weight rollers. My question is, during your explanation I noticed that you are only using the round type of rollers. Can you please explain what the difference is between the Dr. Pulley brand roller weights. That have more of a cam lobe instead of just being round round. Like the ones you are using in this video?
Rollers and Dr pulley actually slide they dont roll. Dr pulley has a fixed sliding surface and at the same as the rollers, Dr Pulley have a very good method of action where the rollers can be used in different surfaces of the diameter. It all depends on the material the rollers/sliders are made of for longevity.
You showed that the belt wasn't going all the way to the edge of the pulley,saying that the extra travel would have been worth a few extra km/h. But you didn't tell us what to do to get the belt to travel the full diameter of the pulley. Could you fill that bit in,thanks.
You have several options. Trial with longer belts without loosing the low gear. Use shims to correct the front pulley spacing without changing the lock nut position on the thread.
thanks bought a DLH variator for my nouvo elegance 135..couldnt figure out why it came with 3 10g 3 11g 3 12g plus three red springs.being 200lbs the 10 and 11s work great..thanks
Just tuned in and subscribed thanks for the very good, informative video. I've got a Sym Jolie scooter where would you recommend I buy my bots from from Australia I want to support the local suppliers so any advice would be greatly appreciated. Thanks again for the vids
I have a 22 Honda Air Blade 150 . It came with 16 gram flyballs (rollers) I put in 20 gram , then I removed the air baffle and tube in the filter casing , took it to shop remapped the ECU and oh boy what a differance .Thiking about putting in a little heavier variator spring . It's not for racing but just cruieing and towing a small cargo trailer .
@@scooterstreetau AS for speed I don't know have not tried that yet . Before is would be hard to spin tire in dirt , now it will put the rubber to the road ,the pick is really goo . Sure looks like I will be going to 20 gram sliders .
In Holland the variator has a backplate that acts asa restrictor ,it limits its expansion. I read that this piece can be removed. Any experience with that? Good video btw. Thanks. :))
HI MATE CAN YOU TELL ME WHAT SIZE ROLLER WEIGHTS I NEED FOR 49CC DIRECT BIKES MOPED TO GET UP HILLS AND BANKS AND PICK UP MORE SPEED THANK YOU PLEASE KEEP POSTING YOUR VIDEOS THANK YOU
I am unfamiliar with this Brand and Model, but I would try a going for 1 gram lighter than the original rollers, tighter clutch spring set and Also look for an unrestricted CDI. Usually the 49cc 4T will accept the 75cc Kit and then your on your way👍

Great video man, can you give me some advice on tuning a 4 stroke . Yamaha xmax 300 . Do you think a variator and rollers would give better accelration ? Do you have any suggestions on rolller weights .
Thank you for comment👍. Yes certainly start at 10% lighter on the roller weight, go for a performance variator which has specific rollers for Xmax and look to include an adjustable clutch system as they work in tandem. This will enhance the transmission performance overall. Def ask Yamaha about the ECU mapping, there may be a different mapping setting for higher performance.
Hello julleboy90, all the content is still very relevant👍. You use a shim to increase (spread) the distance between the variator and the fixed face fan. This allows the belt to sit at the lowest point on the front pulley. May be used when a different size belt is used, wider and longer perhaps.. we like to have the belt very ear to the outside of the variator to allow the highest gearing.
Thank you I really appreciate it love your videos ! Great professional content right to the point no messing around and goofing around and all that BS ! I gave up on scooter swap shop videos, too much f****** around and not enough valuable content !
Hello, I have a problem, I have a Peugeot Speedfight 1 100cc that recently seized up/heat seized. It was not tuned. I then changed the cylinder, piston etc. It now starts up right away, but after a while it dies all of a sudden (as if you had turned off the key) and then I can start it right up again, this usually happens when I go over 60 km/h or uphill. When I changed the cylinder etc, I also cleaned everything thoroughly, such as the carburettor, intake, new air filter, new fuel filter (there was no fuel filter before) new spark plug. I also removed the oil pump and put a metalplate with a gasket over the hole instead, I now mix the oil directly into the gasoline. Some other info that might be important. - When I drive over 60 km/h, it starts to make a noise from the variator (CVT), it´s sounds quite a lot. - When it died, I tried to start it again while it was rolling and then it started right away, but it made a noise from the variator, like something "let go" that had been seized up, like a rubber sound, maybe from the belt. - The variator belt touches the variator cover on the inside and has grinded a cut in the metal. - In the variator, where the weights are, the belt does not go down to the bottom of the wheel. - The clutch bell had turned blue from the heat. - The place where the connecting rod attaches to the crankshaft had turned blue from heat. - There was no fuel filter on it before. But i now saw there is an internal fuel filter in the gastank, can it affect the vacuum if you now have 2 fuel filters. Please help me. Regards Andree.
@@scooterstreetau No i did not, i tested the oilpump and it worked, but i am not sure about the flow. Anyway, i removed it and put a plate over the hole, and now i use premix. What could have caused the seizure then, all i can think of is lack of oil.
@@NorthSurvival At times as a bike ages the air and fuel flow changes and you see unbalanced mixtures, there are many variables here, poor air filtering, weather changes, rubber perishing, blockages etc. As a precaution I check all of the systems and their associated parts and also richen the fuel during testing..
@@scooterstreetau I took it for a testdrive today and after a while it stopped, so i removed the variator cover to check how it looked and the axle where the weights are that goes into the engine was stuck, so i turned it a bit and it let go, and after it was a bit hard to start again. What could this be? I checked the fuel line and the vacuum valve that goes into the gastank and they worked, if it was some bad bearings in the engine would that be enough to stop the engine while running? If it would be some bad bearings wouldn´t that just like vibrate a bit more, and not stop the engine all toghether. Could something in the engine have taken damage when it heatsized? If so what is the most likely to have taken damage.
@@NorthSurvival From your description it does sound as though something has seized internally. Check the piston and and all parts connected to the crankshaft..
Thanks you so much🦘👍. You can run 3 rollers for a short trial only, Not to do long term, double the wear and short lived. Recommend to find the correct total weight, then divide by 6 and then use 6 rollers for this single weight. Trial 6 rollers of the weight 5.5gram, so the total weight is 33 grams. If you do 3 rollers of this weight (5.5g) the engine will rev but the acceleration will drop away after the first 2 or 3 seconds as the weight is not enough to progress the belt through the variator..
You have such great content on you chanel, I shreaded my CVT belt on my gy6 50cc 4 stroke, and replaced it, the belt had no size on it so I think it small case so I went with 669x18x30,,,put everything back together and it wont start,,,replaced battey, coil, plug ,CDI, nothing,,,,could a wrong size belt prevent it from starting? Could I take the belt off and try to start without it on, so frustrating at this point, any advice would be awsome,, TY again!
Thanks for great comments. Sounds like something is bound up. You need to reset the variator, when the belt blows apart the variator usually will get stuck in high gear. Have a good look through the transmission as well, pieces of blown up belt often work their way into crucial moving parts like the pinion gear, etc.
Upgrade the engine capacity. If this is not an option allow the rpm to build before the clutch engages. Do this with lighter rollers, lowest gearing on the belt to variator position (use of shims) and later engagement of the clutch shoe, Use an adjustable clutch. So lighter rollers, adjustable clutch.
Thanks I've always staggered the weights some one told me about the total amount off grams is key buy I forgot exactly the explanation for that. Thanks 82 mini stroker Hawaii 🤙🤙 aloha
Hi guy, i have some question: -what is your recommend clutch shoe material for stop-and-go city riding!? -stock clutch shoe (soft) and carbon-kevlar shoe(hard), which one hit the bell rapidly, and give the best friction force!? -if i choose the more friction shoe, i must choose lighter roller weight to avoid the belt from slip, isn't it!? -for normal riding everyday, we must take off at high/full throttle or just slightly throttle!? Thank you 👍
-Clutch material: Standard clutch is fine, always maintain and clean the shoes and bell housing, upgrade to a higher class when wear is present. -Stock clutch shoe: Street spec or Race spec! Choose what you need for the riding type your doing. -The trans should be balanced, example: if race class go with race class for the entire system. The roller weight determine rpm and also top speed. - Throttle: Depends on the scooter cc. For me on 50cc it is always full throttle and control with the rear brake.
THanks for the support and comment, MZ. Your Address doing 120kph is very good for the UK110. I would leave it alone, already great✌ Most likely the belt is moving to the top gear and the front variator..
So I have a stage6 70cc kit and an exhaust, crank, and intake system and I also have a polini clutch, variator and clutch bell and I was wondering how do I find the perfect rollers, clutch springs and contra spring for my scooter because I am very lost atm
The easiest way to dial in the rollers is to make 1 gram changes from the original, so ride with originals and then change to heavier rollers by 1 gram. Now compare the difference bewteen the 2 different roller sets. Now try 1 gram lighter and between these changes which set has you at the best perfomance.? It is vital to fit an adjustable clutch or tighter clutch springs.
I have honda ruckus with NYC variator/ drive face and right now 6g Dr.pulley slider. I can't get the belt to get top of the variator. I've also tried 5.5g and 5g. What would you recommend to get the belt to the top of the variator?
Was the belt going to the top of the variator when the standard face was fitted? Pen mark the Variator face and rev it up on the main stand with the scoter securley fixed and in fron to f a wall so no movement. Does the pen mark get rubbed off all the way to the top? The rollers are most likely heavy enough to take the belt to 100% so it could be the belt length, the belt width or the rear pulley. When the rear pulley is fully opened ( top gear) is the belt at the total centre? Many questions to ask and answer to isolate what the issue can be.. Start now✌️
Does it matter how the rollers go in like it what direction? I noticed one side is showing metal, the other plastic, should it be facing a certain way? TY for your videos
The metal end that you mention is the end in which the metal weight is inserted into the plastic roller housing. The force of the spinning variator can push the metal insert out of the plastic housing if laid into the variator in an anticlockwise direction. So the plastic cover end of the roller should be facing clockwise in the variators fitted position.
I think i am a little confused...If i am right you mean that using lighter rollers we should have more torque and if we use heavier rollers we have more speed. Am i right?
It is so much more complicated than that, the best way to gain an understanding is to fit different rollers weights and see how they effect the movement of your scooter. So try a lighter weight and test ride the scoot, now increase the weight and test again to get a quick answer as to how these change the acceleration and higher speeds.
Straight out SUB, Love it😁. What size are your current rollers? Let's say 7.5 gram, try 6 gram and then make small weight adjustments from there. Too light and it will not maintain the pull and over rev so trial and test🎉
I really appreciate your explanation on the CVT. Can I please ask some advice? Sorry in advance for the long message. What if I have a Chinese GY6 50cc engine with 80cc bbk and aftermarket exhaust with Keihin carburetor and higher gear ratio to get better top end. I haven't done a thing with the CVT except for variator which wasn't much. I think I may even be running my stock rollers again. I know that was stupid not to do anything until now but should I use the 1500 or 2000 spring and what size sliders or rollers should I be running? Also does a performance clutch with larger pads make any performance difference compared to a new stock clutch or should I just concentrate on the springs and weights? I am experiencing a big from like 15-30 mph and it seems like I should be getting a better top end speed. I'm currently getting about 42 flat and 50-52 downhill lol. Can you please offer me some advice? I would truly appreciate your help brother!
I would try some lighter rollers and replace any worn parts on the engine including the transmission. Look to change the clutch springs to 2-3000rpm or even higher if the engine is revving. You will need to check the variator top speed by pen marking the face and riding. This will guide you as to which rollers, this is trial and test, try lighter rollers and then try heavier.. The performance clutch is good but buy quality and try for an adjustable clutch like Polini G3. Check the main jet on the carby make sure there is enough fuel and the engine not running lean..
@@scooterstreetau thanks so much for replying! I asked several and no one would answer except for you. So I'll try the 2000 rpm spring and some 6 gram Mr. Pulley sliders? You think this should be sufficient and then try the marker deal on the variator? Do you know if they make the polini G3 clutch for a 50cc qmb139 Chinese motor?
@@mikecuev820 You are welcome, thankyou for supporting our Channel🙋♂️. Yes, try the tighter springs but the engine must be revving to engage with better acceleration. With the rollers/Sliders you must trial different weights to move to a better performing variation. So try 6G and then 6.5G and so on until you have the best performance.. Yes Polini do make a suitable clutch..
Hi \ thank you for this Great video I have Yamaha majesty 250cc Scooter can I mix 3 of 13 gm light rollers with his heavy original 3 of 18 gm or this is big difference!!? Can you advise me what is the best choice please ?
Your welcome, thank you. If the dimension of the roller is the same and only the weight is different then YES. BUT We use this combination method to find the correct weight for testing only. Once we have found the correct overall weight we prefer to use all rollers of the same weight. example: If you have 3 x 13g = 39 added with 3 x 18g = 54 then the total of all = 93g. Divide the total weight by the number of rollers, in this case 6 and use 15.5gram weight for all of them.👌
@@scooterstreetau Will I'm always use the original 6× 18g but I feel the Scooter heavy to move for the first moments thin will be normal Thin I got to use 6×13g rollers but not a very good results make to me ! high Rpm and high engine sound I think the engine loose some power in this case !!
Great video, explained really well but I could do with some help with my sons 50 Aerox. It pulls off really slow until it gets to 21mph then boom! It picks up & goes really well. However sometimes it pull off as it should, like its actually in 1st with a good pull but hardly ever. Its like its in 2nd whilst trying to pull off & it's the only way I can explain it. Malossi variator installed, changed clutch spring to the white one, changed to Malossi belt, changed to the weights that came with the kit & Malossi air filter installed. All this was to get better top end which as worked (50) but bottom end result is poor! He's only just passed his CBT and I think its dangerous with him trying to pull off like this and trying to get up hills etc. Please help if you can as I want it to be safe. PcG
Was it running well prior to fitting all of these parts?? Also watch this video for an explanation. th-cam.com/video/7TDvOnsSbhc/w-d-xo.html&ab_channel=ScooterStreet
hello, I really like how knowledgeable you are with the aprilia sr50. my year is 1999 and 2000 carb model. I'm interested in making it rear facing carb but not sure of the modifications I will or might need to do. I had one before but I had stage 6 rear intake with 28mm pkw carburetor. I'm not sure what mod if there was one to make this setup work. can you help me figure out this? I want to duplicate what I had. just not sure of the frame modification. do I need to do this?
Yes you can, I may do this for trial only and then move to having each roller of the same weight. Total of this combo is 39gram so divide by 6 to get each roller being 6.5gram. When 3 rollers are heavier than the other 3, the heavier will do all the pushing and wear very fast.
I have a 2012 Piaggio Typhoon 50cc 4T. What do you recommend to upgrade the rollers, clutch, etc...in order to get faster of the line and going up hill? I want to modify these items to get more torque and speed. Do you recommend replacing the carburetor kit? How can I deactivate the restrictor?
The small engine 4 stroke is difficult because it simply produces very little power. Try lightening the roller weight by 1 gram for each roller and use an adjustable clutch to fine tune the engagement of the power to the wheel. Check for derectrictions in the trasmission, carby and the exhaust. Fit a Malossi single air filter and raise the main jet 1 point.
@@scooterstreetau I've been watching several of your videos with these upgrades. Question is, Is the Piaggio 50cc 4t any different from the Fly you show or the Vespa? Are they basically the components?
Hi great video. I used NCY 12g rollers and managed to get my Honda Navi up to 52mph. But at the top end speed I’m getting a vibration, any thoughts on why? I did notice the 12g rollers have different looking sides on them. Do you know if they all have to go in the same direction? Rollers did not come with any directions and can’t seem to find any information or videos on it. I’m thinking I’ve reached peak performance with the 12g rollers but not sure. Any thoughts or suggestions Thank you
I’ve got a 2021 znen 50cc. I could be running flat at 35-40mph and hit a hill and drop instantly to 10mph. I weigh under 200lbs. What would be the best set up for this transmission-qmb139 engine?? Any suggestions would be appreciated. Thanks guys.
The hill is effectively adding more load to the engine so the transmission should automatically lower the gearing. You can better achieve this with lighter rollers in the variator and a heavier torque spring in the clutch but all must be balanced.. Take care not to go too far with these adjustments because ultimately the engine is not producing enough power, consider a big bore kit.
Dr Pulley Slides are a great example of having the Closed End. So if we have the variator laying on a flat surface, as we place the Sliders into the Variator slot, the DR Pulley writing will face Anti-Clockwise.↪ watch from 7:40
Great tutorial. I have changed mine to molassi Multivar variator. The rollers are 8 gr. Feel the rpm is high before the bike move. Should I be looking into the clutch springs
@@swimwithcoachraven1532 ok well you are on the right track, RPM higher with a later engagement of the clutch to boost from the start position. Tighter clutch springs will allow the rpm to build, so give the springs a go.
My new Yamaha NMax 155 scooter vibrates annoyingly at 10 KPH when accelerating. Can you tell me if changing the roller weights will fix it, and if I will need heavier or lighter rollers? If it matters, I’m riding a bike that may be made for the Philippines and lighter people, and I’m heavier than the average Filipino.
You really need to find out what is causing the issue. Changing the rollers most likely will not make a difference. Just and idea to check the rear pulley Clutch shoe condition. The vibration maybe engine bushes, a loose part of the engine. Get in there and have a good look making eliminations one by one😉
The scooter has a maximum physical limit for the transmission ( belt movement) it is about optimising the rpm and the progression of the belt to the top of the variator. Tuning the rollers to suit the engine is the art. Running with too light of a set of rollers will allow rpm but may limit or slow down the optimal gearing change to give the speed increase. Best to try for yourself, go for a roller 2 gram heavier than factory and then try a set 2 gram lighter, then you will know, wykyk.
Yes you can say that to have a very general understanding. Thanks for SUB🐰🙏 Hard to generalise but I would say this. " Starting from and making comparison too the factory rollers you will find: The heavier you go with the roller weight you will slow down the acceleration. The lighter you go, you will increase the engine RPM and accelerate the engine for a moment and then the speed will fail to increase due to the light weight of the roller." With a 50cc we 10% lighter on the rollers. with a 70cc we 10% heavier the rollers. So much more comes into play when you set up Upgraded cylinder with upgraded exhausts.
@@thefallenking7538 Rollers and sliders both slide, you will notice flat spots on the rollers due to this sliding action. Named rollers for their shape. Sliders benefit is they offer a larger surface area of slide and wear slower compared to the rollers if having the same composition. So most important thing is, material and weight. Go for it👌
Hi at the moment I've just got a stock Typhoon which is deristricted. My daily travel has a lot of hills involved and was woundering if getting lighter rollers could help with that?
I am guessing the Navi follows the PCX transmission, The PCX 2021 variator from Malossi is 5118776. If you check the spare parts and confirm against the original sizes and dimensions of the Navi you may find they are the same.. Do the research first😁👌
Leave the standard rollers in if you need top speed. Tuning a variator is all about finding the optimal weight, this gives the highest RPM, the strongest pull and reaches the top speed. If you don't want to go through the task of tuning just try to fit 0.5 of a gram lighter on each roller than the original roller weight. This will give what is required with smallest effort.
They are developed to increase the effectiveness of the transmission by maintaining optimal RPM. With different weights the variator can be fine tuned. This can increase the acceleration and also top speed. The ramp slot that the rollers are housed have a different angle, some kits have upgraded the size of the guides with smaller tolerances. Often the performance variator is cheaper than the OEM. Saying this, there are cases where the factory Variator will have the same performance as the aftermarket Variator.
Most scooter parts from China labeled high performance are just “cheap replacement” parts. It’s more important that your transmission is properly tuned to keep engine rpm in the power band. The physics is the same no matter how much you paid for your variator.
Hi ! Impressive video. I have a question . I have a sym hd 300 , polini variator 14g rollers and the blue hard contra, also free dna air filter . The manual says that at 8000rpm max h.power. the rpm has increased from before , and 0-100 very fast but then drop , and the max speed comes vary vary latter and the rpm gies to 8100-8200? What mod would you suggest in order to reduce the drop at higher speeds? And do you suggest a aftermarket muffer?
Thank you.. Try varying the roller weight, Go heavier and then slowly reduce weights, so you can see what the change makes on the road. The spring, try the original spring and then again varying the rollers.
@@christos5635 Aftermarket exhaust: Great sound, more noise awareness for drivers. At this cc it gives good mid-range power and can add to the top speed, you need the variator/transmission tuning and you have the variator.
Hello, I just upgrade my artistic spec jog from 50cc to a 70cc kit. Wich set weight of rollers do you recommend me?. I have on the stock exhaust, I noticed to scooter is a little sluggish to get up and go. Thank you
Hello, i have a aprilia sr 50 2020 E4 with piaggio engine. The standard rollers on it are 7,2 or 7,5. I changed the rollers to 6,1 but it accelerates very slowly, like the engine revs a bit but i can reach max 45 50 km/ h and it takes a little bit more time than it took when i had the standard rollers
The scooter is designed to go slow according to regulations, it needs to be derestricted in order to gain more power and top speed. Changing the rollers is one part of the puzzle but the CDI/ECU will need mods and also the carby and def. the exhaust.
I still don't understand the steps to try a suitable roller by combining light and heavy rollers. Please explain the steps, and what roller indicator is right for me. I weigh 172 pounds and the factory default rollers are 11 grams, the springs have been changed to 1000 rpm, but when I go up the hill my scooter struggles when I accelerate
Ok, When you have time to change and test ride you should begin. Basically all you do is start with 11gram rollers, mark the variator face with the black pen and fit 2000rpm clutch springs. Go for a test ride and note the performance. Go back to your garage and replace the rollers for 10gram and visually check to mark sure the pen mark has been rubbed away from the belt travelling to the top of the variator. Re-mark after each roll change and always check. repeat the same ride as the previous again noting the change from the first ride. The difference in the way the engine acclerates, holds speed and drops when throttle off shoud be noted. Find the best performing set of rollers weights for your setup. Once done you can experiment with hight tension Torque springs and clutch springs again note the effect each part has on the performance of your scoot. Make sublte changes for best performace.
Hi Scooter Street, I am Marc with 70 kilograms of bodyweight, I just want to have an advices from you with my Yamaha 50cc scooter set-up upgraded into 47mm Block and Re-chambered Cylinder Head, 70-90 V8 exhaust Pipe, 24mm Carb, Kitaco Racing CDI, 13:34 Secondary Gear, Racing Coil, CT manifold with .35mm Polini Petals, 1000RPM Center Spring and 1000RPM Clutch Spring, Cheap Racing driveface and Pulley set, stock Clutch Lining and Bell, my question is what roller weights should i try to reach the right acceleration and Top/High?
Hi Marc, difficult to have an exact answer. Like all the other variator questions the best answer is to start at the factory rollers and reduce from there. There are instances where the roller weights are increased but usually lighter will be more effective. Trial and testing.
what is the excellent combination of weight of of flyball if you want more torque because we leave on a mountanious area. i have only 110cc of scooter. thank you
I have a Wolf Blaze 2 150cc. What kind of rollers should I get to get faster take off and keep maximum speed? I’m in Florida and average speed is about 45 so I want to get to at least 50mph rather sooner. TIA. Stock scooter except carburetor
Hi do you sell or know where to buy as im in sydney i have my first scooter its a scarabeo 200ie 2012 what do you recommend for better take off and do i have to upgrade the jet needle.
I just purchased a 2019 metropolitan, how can I make this scoot to hit 45 mph and get there quickly? It's completely stock bought it with only 15 miles on the odometer. Currently it hits 37-38 mph with me weighing 205 lbs.
Yes, you need to make sure they all face the same direction, with the smooth (non beveled) side facing clockwise. Double check the direction with your manual. Also, I think my manual called them weights.
Good question! When rollers are manufactured the weighted insert slides into the outer shell. Some rollers have an end in which the weight enters and the shell has a capped end to stop the weight going all the way through the shell, this capped end is called the 'closed end' and should always face away from the direction of rotation when placed in the Variator. Other rollers are glued and do not have a closed end so it will not matter. So always look for the closed end when placing the rollers.
Great video!! I have a question I run a piaggio typhoon with 70cc kit Main carb with 74 jet Malossi exhaust Malossi air filter But the problem is that when I go to a big hill it is like the spring can’t change the transmission (I have factory heavy rollers and factory soft spring from 50cc) is it better to leave the rollers and take a harder spring ? Or is it going to put to much pressure on the belt? If I change the rollers with lighter is it going to lose grip on the belt ? (Sorry for my English ,I hope I am understandable)
Well Thank you😁 we appreciate the views and comments.. A few things, make sure the carby is tuned, the air-mix screw all the way in and then 1 single turn out, set and forget. Is the jet size large enough? Is it running lean? The factory rollers are 7.5. Try a 7.2 or 7 Gram set ensuring the belt is always reaching the outer. Diameter of the variator. I suggest this because it is easier to work out the solution by changing the rollers instead of the Torque spring. By the way make sure the clutch twist rotation is smooth and not stepped.
@@scooterstreetau I have 6 gram rollers I have some holes to the filter box also … And the air screw is half open I will try Malossi green spring in order to help it with the transmission….if it doesn’t change I will buy new even lighter rollers to try again. My plug color is brown
@@flawlessmusic8850 For variator testing , remove 2 rollers to see if it makes a difference, there are many ways to test with the parts that you already have, I am not to sure about holes in the airbox unless you have the carby tuned to suit.. too much air can lean the mix and the power is reduced and it bogs the engine under heavy throttle..
@@scooterstreetau Ok perfect I will try removing rollers Thank you !!! I have seen all your videos on your Chanel 😂 I wish I had Malossi piston set but I have only Malossi head with a cheap 47 kit 😂
I put on a 70kit and pipe and changed the carb (12,5 original) to 82 jet, i have 4,6g and it goes great on idle but if you go for full throttle it revs up to 4k and the wheel doesnt even turn around, please help
4.6 is probably too light. Go back to standard rollers or only 1 gram lighter. Now get the carby jet correct first and then come back to the transmission.
Hi Scooter street! I recently bought a china 2stroke scooter. It had 4g rollers when i got it, they were worn, with flat spots. I replaced them with 6g rollers, it had poor acceleration and top speed then. Now i put in 5g rollers, it seems to have good performance now, but im afraid it is reving too high at high speed. It has leovince exaust on it and stock 50cc cylinder. Can scooters get damaged from reving too high? I dont know how much rpm is normal, no experience with scooters
No, it cant really rev too high so don't worry about high RPM. 2 stroke engines are high revving engines, a near standard scooter such as yours cant really over rev to the point of damage unless there is a serious mechanical issue. You should try the marking of the variator to see if the belt is reaching the top of the variator. Also a heavier torque spring will counter the heavier rollers. Do some trialling and come out with the best outcome for the transmission..
We suggest that you trial different weights to get the bet performance for your set up. Once you find this best performance weight, then find the total weight of all of the rollers and divided this total by 6. This is the weight that each roller should be. If an 8 roll variator then divide by 8.
I have no firm answer. You must trial different weights to find this out for yourself. The standard rollers will give the highest top speed but may not allow the best acceleration. A slightly lighter set of rollers will also give the highest top speed and the acceleration will start to increase.. If you reduce the weight by small increments you will eventually find a weight that will no longer get you to the highest top speed (they will be too light to drive the variator to highest belt position). So you need to find the lighter set of rollers that increase the acceleration and also still provide the highest top speed. This will be the optimal set. At a guess try 12-15% less than standard.
Hi, I have taken off many variatiors, Im tryn to get the variator off of my prescott 50i gy6 and the nut will not come off, I tried my usual torque wrench that always works and my buddy came by with large set of socket wrench and he couldnt do it, have you had a situation where you cant get the variator off and what did you do? Id hate to not be able to upgrade this scooter TY again!!!
That sounds pretty frustrating! Not familiar with that particular make but the GY6 engines obviously all share a fair bit of commonality. I would recommend a rattle gun/torque driver with minimum 350-400Nm torque. In most cases you'll need a fair bit more torque to undo a factory nut than to retighten it. They make have used some thread lock in the factory as an anti-tamper, or it may just be corroded or stuck on. If a rattle gun still wont get it off, I'd recommend taking it to a mechanic.
Sorry, I still don't get what's the purpose of mixing different weights. Since the heavier weight are always going to go up the ramp faster from the centrifugal force. Also, I don't really get the part how the weight of the roller affect the ride. I get that with heavier rollers it means it will go up the ramp quicker(lower engine rpm) and with the lighter ones it takes revving up the engine more to get the rollers to the edge. When the rollers get to the edge, the belt moves outwards, effectively increasing the gear so to speak, you'd have faster wheel rpm and less torque right? Or is it the other way? That the torque is highest when the rollers are up on the ramp? Does that mean with lighter rollers you'll likely have more torque, better acceleration at lower to mid speed for instance say 20km/h -60km.and with heavier rollers youd have weaker acceleration at the same speed range?
The combined push from all of the weights changes the variator position. The best thing for you to do is to see it in action with a simple experiment. Take your variator and weigh the factory rollers, now place a new set of rollers which is 50% of the original weight. Run a test ride and note the difference. Repeat this experiment with 50% heavier than original rollers and again make notes. The belt moves as the rollers move. YT search the variator in action and you can see this entire experiment.
Using a longer belt will help get you to a higher gear (top speed). You will be limited by the rear pulley, so use a bet that maximises the diameter of the smallest pulley. Do keep the same width on the belt, do not go wider..
When it comes to replacing the variator rollers then many mechs use grease on rollers & they say that it'll make scooter noise less. But few of them strictly prohibits of using it as it's the dry clutch thus no grease is needed. What is the correct method according to you in gearless scooter. I've got a Honda Scooter that's causing vibrations when start accelerating it from 0 then after reaching 5miles per hour all vibrations disappears. But at every stop & go, it's visor & body vibrates which is problematic in slow traffic. Mech saying that variator rollers needs to be replaced & he's suggesting me to grease the new rollers before putting in. It's a big confusion😢
What is correct is what you find the best outcome for you. We never use grease in this area unless the variator is sealed and therefore requires grease. Find out why the vibrations and correct this issue instead of a band aid fix. Again, find what is best for you my friend👍👍
@@abhimd3455 Some larger capacity scooters come with sealed variator, they are sealed with grease inside. The grease is inside the variator and captive by orings and seals so the grease does not venture out on to the belt and dry faces. Grease is also applied to the shaft and has an o'ring to keep the grease in the lubed section.
@@scooterstreetau Thanks you so much for clarification. My Honda Activa 5g has 110cc engine & basically comes with an open variator without any grease as I may see when opened it for very first time. Thanks again
@@5hvnjyybb37 The only way to Derestrict the scooter is to remove them all. There are no shorter cuts, the removal of restriction is the most simple way.
OK I know after market variators are different in its ramping. I bought a malossi variator with 9 gram rollers for my kymco super 8 50cc 2t. I found out stock is 8 gram rollers. I've bought my leo vince exhaust. How would 9 grams be in my scooter
Try the 9 gram Malossi recommend, you may find it limits the initial rev. So move the a 7.5gram set. You need an exhaust for the Super 8 because they are not so super in their speed.
Ok I have Leo Vince exhaust, malossi cut out filter for air box. Could you please tell me what size main jet I need for kymco super 8 2t 50cc. I'm in toowoomba so a little different altitude

Best video on this subject. Forget the others.
GP, Thank you so much for the support🦘🦘.
Wonderful explanations..so if i am to understand..how will lighter weights vs heavy weights affect top speed vs acceleration? Can u help me with that?
lighter rollers allows reduced load so energy to rotate is less and so rotation is quicker. Too light and the gearing will progress to slowly causing an over rev.
It takes more energy to rotate the heavier rollers so the accelration is reduced.
Top speed is created by optimising the roller weights.
You can remove the metal spacer in the roller and drill each spacer out to the exact weight you need.
Yes, All true😊. Many ways to get the same result.
Very good explanation on how a varaitor works with different weight rollers.
My question is, during your explanation I noticed that you are only using the round type of rollers. Can you please explain what the difference is between the Dr. Pulley brand roller weights. That have more of a cam lobe instead of just being round round. Like the ones you are using in this video?
Rollers and Dr pulley actually slide they dont roll.
Dr pulley has a fixed sliding surface and at the same as the rollers, Dr Pulley have a very good method of action where the rollers can be used in different surfaces of the diameter. It all depends on the material the rollers/sliders are made of for longevity.
You showed that the belt wasn't going all the way to the edge of the pulley,saying that the extra travel would have been worth a few extra km/h.
But you didn't tell us what to do to get the belt to travel the full diameter of the pulley.
Could you fill that bit in,thanks.
You have several options. Trial with longer belts without loosing the low gear. Use shims to correct the front pulley spacing without changing the lock nut position on the thread.
thanks bought a DLH variator for my nouvo elegance 135..couldnt figure out why it came with 3 10g 3 11g 3 12g plus three red springs.being 200lbs the 10 and 11s work great..thanks

@@jamesbraun7709 😆 sounds cool.
My question is, which roller weights give a higher top speed with weaker acceleration? Heavier or lighter than OEM?
If the belt travel is at highest potential then heavier rollers will make no difference.
Amazing video helps so much in upstanding what's going on
Glad to be of service!
In Holland the variator has a backplate that acts asa restrictor ,it limits its expansion. I read that this piece can be removed.
Any experience with that?
Good video btw. Thanks. :))
That is correct, remove the cage over the ramp plate, usually 3 screws retain this. Thanks Bro.
Do you know why my scooter wouldn’t wanna shift in the 2nd gear, like i take off then it just revs and hits like 35 40 km/h and revs to much
Are your rollers too light, what have you changed recently? Check the variator, belt and rear pulley function.

Great video man, can you give me some advice on tuning a 4 stroke . Yamaha xmax 300 . Do you think a variator and rollers would give better accelration ? Do you have any suggestions on rolller weights .
Thank you for comment👍. Yes certainly start at 10% lighter on the roller weight, go for a performance variator which has specific rollers for Xmax and look to include an adjustable clutch system as they work in tandem. This will enhance the transmission performance overall. Def ask Yamaha about the ECU mapping, there may be a different mapping setting for higher performance.
@@scooterstreetau cheers mate , appreciate it
@@kryptonitefitness Welcome.
Now this video is old, but can you explain shimme vario. How far up on the vario will you go? Thanks for your videos
Hello julleboy90, all the content is still very relevant👍. You use a shim to increase (spread) the distance between the variator and the fixed face fan. This allows the belt to sit at the lowest point on the front pulley. May be used when a different size belt is used, wider and longer perhaps.. we like to have the belt very ear to the outside of the variator to allow the highest gearing.
Thank you I really appreciate it love your videos ! Great professional content right to the point no messing around and goofing around and all that BS ! I gave up on scooter swap shop videos, too much f****** around and not enough valuable content !

Hello, I have a problem, I have a Peugeot Speedfight 1 100cc that recently seized up/heat seized. It was not tuned. I then changed the cylinder, piston etc. It now starts up right away, but after a while it dies all of a sudden (as if you had turned off the key) and then I can start it right up again, this usually happens when I go over 60 km/h or uphill.
When I changed the cylinder etc, I also cleaned everything thoroughly, such as the carburettor, intake, new air filter, new fuel filter (there was no fuel filter before) new spark plug. I also removed the oil pump and put a metalplate with a gasket over the hole instead, I now mix the oil directly into the gasoline.
Some other info that might be important.
- When I drive over 60 km/h, it starts to make a noise from the variator (CVT), it´s sounds quite a lot.
- When it died, I tried to start it again while it was rolling and then it started right away, but it made a noise from the variator, like something "let go" that had been seized up, like a rubber sound, maybe from the belt.
- The variator belt touches the variator cover on the inside and has grinded a cut in the metal.
- In the variator, where the weights are, the belt does not go down to the bottom of the wheel.
- The clutch bell had turned blue from the heat.
- The place where the connecting rod attaches to the crankshaft had turned blue from heat.
- There was no fuel filter on it before. But i now saw there is an internal fuel filter in the gastank, can it affect the vacuum if you now have 2 fuel filters.
Please help me.
Regards
Andree.
Did you find the cause for the Seizure, prior to riding? If not it should be investigated.
@@scooterstreetau No i did not, i tested the oilpump and it worked, but i am not sure about the flow. Anyway, i removed it and put a plate over the hole, and now i use premix. What could have caused the seizure then, all i can think of is lack of oil.
@@NorthSurvival At times as a bike ages the air and fuel flow changes and you see unbalanced mixtures, there are many variables here, poor air filtering, weather changes, rubber perishing, blockages etc. As a precaution I check all of the systems and their associated parts and also richen the fuel during testing..
@@scooterstreetau I took it for a testdrive today and after a while it stopped, so i removed the variator cover to check how it looked and the axle where the weights are that goes into the engine was stuck, so i turned it a bit and it let go, and after it was a bit hard to start again.
What could this be? I checked the fuel line and the vacuum valve that goes into the gastank and they worked, if it was some bad bearings in the engine would that be enough to stop the engine while running? If it would be some bad bearings wouldn´t that just like vibrate a bit more, and not stop the engine all toghether.
Could something in the engine have taken damage when it heatsized? If so what is the most likely to have taken damage.
@@NorthSurvival From your description it does sound as though something has seized internally. Check the piston and and all parts connected to the crankshaft..
Thanks ! Really good explanation.
Thank you, glad it was helpful🙌
Subscribed! Well explained. Thank you. Got the info I needed.
Can I run just 3 rollers?
Thanks you so much🦘👍. You can run 3 rollers for a short trial only, Not to do long term, double the wear and short lived. Recommend to find the correct total weight, then divide by 6 and then use 6 rollers for this single weight. Trial 6 rollers of the weight 5.5gram, so the total weight is 33 grams. If you do 3 rollers of this weight (5.5g) the engine will rev but the acceleration will drop away after the first 2 or 3 seconds as the weight is not enough to progress the belt through the variator..
You have such great content on you chanel, I shreaded my CVT belt on my gy6 50cc 4 stroke, and replaced it, the belt had no size on it so I think it small case so I went with 669x18x30,,,put everything back together and it wont start,,,replaced battey, coil, plug ,CDI, nothing,,,,could a wrong size belt prevent it from starting? Could I take the belt off and try to start without it on, so frustrating at this point, any advice would be awsome,, TY again!
Thanks for great comments. Sounds like something is bound up. You need to reset the variator, when the belt blows apart the variator usually will get stuck in high gear. Have a good look through the transmission as well, pieces of blown up belt often work their way into crucial moving parts like the pinion gear, etc.
What advice could you give me please for more more and speed talking off please on a gilera runner 125st thank you
Upgrade the engine capacity. If this is not an option allow the rpm to build before the clutch engages. Do this with lighter rollers, lowest gearing on the belt to variator position (use of shims) and later engagement of the clutch shoe, Use an adjustable clutch.
So lighter rollers, adjustable clutch.

Hi guy, i have some question:
-what is your recommend clutch shoe material for stop-and-go city riding!?
-stock clutch shoe (soft) and carbon-kevlar shoe(hard), which one hit the bell rapidly, and give the best friction force!?
-if i choose the more friction shoe, i must choose lighter roller weight to avoid the belt from slip, isn't it!?
-for normal riding everyday, we must take off at high/full throttle or just slightly throttle!?
Thank you 👍
-Clutch material: Standard clutch is fine, always maintain and clean the shoes and bell housing, upgrade to a higher class when wear is present.
-Stock clutch shoe: Street spec or Race spec! Choose what you need for the riding type your doing.
-The trans should be balanced, example: if race class go with race class for the entire system. The roller weight determine rpm and also top speed.
- Throttle: Depends on the scooter cc. For me on 50cc it is always full throttle and control with the rear brake.
Variater part's names Ramp plate, Rollers,
Yes: Ramp plate, rollers, guides, basket or housing, shaft or hub.👍
Great video, thank you…I have a Suzuki address110 bike that has reached 120 km, would you advise me to put heavier rollers ?
THanks for the support and comment, MZ. Your Address doing 120kph is very good for the UK110. I would leave it alone, already great✌ Most likely the belt is moving to the top gear and the front variator..
So I have a stage6 70cc kit and an exhaust, crank, and intake system and I also have a polini clutch, variator and clutch bell and I was wondering how do I find the perfect rollers, clutch springs and contra spring for my scooter because I am very lost atm
The easiest way to dial in the rollers is to make 1 gram changes from the original, so ride with originals and then change to heavier rollers by 1 gram. Now compare the difference bewteen the 2 different roller sets. Now try 1 gram lighter and between these changes which set has you at the best perfomance.? It is vital to fit an adjustable clutch or tighter clutch springs.
@@scooterstreetau ok thanks this is very helpful

Very nice comment, thank you🙌
I have honda ruckus with NYC variator/ drive face and right now 6g Dr.pulley slider. I can't get the belt to get top of the variator. I've also tried 5.5g and 5g. What would you recommend to get the belt to the top of the variator?
Was the belt going to the top of the variator when the standard face was fitted? Pen mark the Variator face and rev it up on the main stand with the scoter securley fixed and in fron to f a wall so no movement. Does the pen mark get rubbed off all the way to the top? The rollers are most likely heavy enough to take the belt to 100% so it could be the belt length, the belt width or the rear pulley. When the rear pulley is fully opened ( top gear) is the belt at the total centre? Many questions to ask and answer to isolate what the issue can be.. Start now✌️
Does it matter how the rollers go in like it what direction? I noticed one side is showing metal, the other plastic, should it be facing a certain way? TY for your videos
The metal end that you mention is the end in which the metal weight is inserted into the plastic roller housing. The force of the spinning variator can push the metal insert out of the plastic housing if laid into the variator in an anticlockwise direction. So the plastic cover end of the roller should be facing clockwise in the variators fitted position.
I think i am a little confused...If i am right you mean that using lighter rollers we should have more torque and if we use heavier rollers we have more speed.
Am i right?
It is so much more complicated than that, the best way to gain an understanding is to fit different rollers weights and see how they effect the movement of your scooter. So try a lighter weight and test ride the scoot, now increase the weight and test again to get a quick answer as to how these change the acceleration and higher speeds.
I subbed!What rollers should i get for a better start,i wanna tune my scooter for wheelies
Straight out SUB, Love it😁. What size are your current rollers? Let's say 7.5 gram, try 6 gram and then make small weight adjustments from there. Too light and it will not maintain the pull and over rev so trial and test🎉

I really appreciate your explanation on the CVT. Can I please ask some advice? Sorry in advance for the long message. What if I have a Chinese GY6 50cc engine with 80cc bbk and aftermarket exhaust with Keihin carburetor and higher gear ratio to get better top end. I haven't done a thing with the CVT except for variator which wasn't much. I think I may even be running my stock rollers again. I know that was stupid not to do anything until now but should I use the 1500 or 2000 spring and what size sliders or rollers should I be running? Also does a performance clutch with larger pads make any performance difference compared to a new stock clutch or should I just concentrate on the springs and weights? I am experiencing a big from like 15-30 mph and it seems like I should be getting a better top end speed. I'm currently getting about 42 flat and 50-52 downhill lol. Can you please offer me some advice? I would truly appreciate your help brother!
I would try some lighter rollers and replace any worn parts on the engine including the transmission. Look to change the clutch springs to 2-3000rpm or even higher if the engine is revving. You will need to check the variator top speed by pen marking the face and riding. This will guide you as to which rollers, this is trial and test, try lighter rollers and then try heavier.. The performance clutch is good but buy quality and try for an adjustable clutch like Polini G3. Check the main jet on the carby make sure there is enough fuel and the engine not running lean..
@@scooterstreetau thanks so much for replying! I asked several and no one would answer except for you. So I'll try the 2000 rpm spring and some 6 gram Mr. Pulley sliders? You think this should be sufficient and then try the marker deal on the variator?
Do you know if they make the polini G3 clutch for a 50cc qmb139 Chinese motor?
@@mikecuev820 You are welcome, thankyou for supporting our Channel🙋♂️.
Yes, try the tighter springs but the engine must be revving to engage with better acceleration.
With the rollers/Sliders you must trial different weights to move to a better performing variation. So try 6G and then 6.5G and so on until you have the best performance.. Yes Polini do make a suitable clutch..

I have Yamaha majesty 250cc Scooter can I mix 3 of 13 gm light rollers with his heavy original 3 of 18 gm or this is big difference!!?
Can you advise me what is the best choice please ?
Your welcome, thank you. If the dimension of the roller is the same and only the weight is different then YES. BUT We use this combination method to find the correct weight for testing only. Once we have found the correct overall weight we prefer to use all rollers of the same weight. example: If you have 3 x 13g = 39 added with 3 x 18g = 54 then the total of all = 93g. Divide the total weight by the number of rollers, in this case 6 and use 15.5gram weight for all of them.👌

However sometimes it pull off as it should, like its actually in 1st with a good pull but hardly ever. Its like its in 2nd whilst trying to pull off & it's the only way I can explain it.
Malossi variator installed, changed clutch spring to the white one, changed to Malossi belt, changed to the weights that came with the kit & Malossi air filter installed. All this was to get better top end which as worked (50) but bottom end result is poor! He's only just passed his CBT and I think its dangerous with him trying to pull off like this and trying to get up hills etc. Please help if you can as I want it to be safe. PcG
Was it running well prior to fitting all of these parts??
Also watch this video for an explanation.

Привет есть ссылка на магозин, где купить вариатор и другие запчасти на априлия Sr50r. Спасибо.
hello, I really like how knowledgeable you are with the aprilia sr50. my year is 1999 and 2000 carb model. I'm interested in making it rear facing carb but not sure of the modifications I will or might need to do. I had one before but I had stage 6 rear intake with 28mm pkw carburetor. I'm not sure what mod if there was one to make this setup work. can you help me figure out this? I want to duplicate what I had. just not sure of the frame modification. do I need to do this?
Hi Mike, Thank you mate🦘. You may have the early Minarelli engine. Can you confirm? The Aprilia forum might be more useful than me.
I have just bought a 125 scooter sym which gives 12hp what i need to earn more horsepower??
You can fit a 150cc or a 160cc cylinder kit or higher and also the tuning parts to go with it.
VERY CLEAR EXPLANATION. THANKS FOR SHARING.🇺🇲✌️👍
Your welcome, thanks for taking the time to comment🦘
Can i do 8gx3 and 5gx3 rollers or is the difference to big?
Yes you can, I may do this for trial only and then move to having each roller of the same weight. Total of this combo is 39gram so divide by 6 to get each roller being 6.5gram. When 3 rollers are heavier than the other 3, the heavier will do all the pushing and wear very fast.
@@scooterstreetau Thank you for the answer :)

I have a 2012 Piaggio Typhoon 50cc 4T. What do you recommend to upgrade the rollers, clutch, etc...in order to get faster of the line and going up hill? I want to modify these items to get more torque and speed. Do you recommend replacing the carburetor kit? How can I deactivate the restrictor?
The small engine 4 stroke is difficult because it simply produces very little power. Try lightening the roller weight by 1 gram for each roller and use an adjustable clutch to fine tune the engagement of the power to the wheel. Check for derectrictions in the trasmission, carby and the exhaust. Fit a Malossi single air filter and raise the main jet 1 point.

Hi great video. I used NCY 12g rollers and managed to get my Honda Navi up to 52mph. But at the top end speed I’m getting a vibration, any thoughts on why? I did notice the 12g rollers have different looking sides on them. Do you know if they all have to go in the same direction? Rollers did not come with any directions and can’t seem to find any information or videos on it. I’m thinking I’ve reached peak performance with the 12g rollers but not sure. Any thoughts or suggestions Thank you
The vibration could be coming from any rotational part. All parts must be checked and balanced.
I’ve got a 2021 znen 50cc. I could be running flat at 35-40mph and hit a hill and drop instantly to 10mph. I weigh under 200lbs. What would be the best set up for this transmission-qmb139 engine?? Any suggestions would be appreciated. Thanks guys.
The hill is effectively adding more load to the engine so the transmission should automatically lower the gearing. You can better achieve this with lighter rollers in the variator and a heavier torque spring in the clutch but all must be balanced.. Take care not to go too far with these adjustments because ultimately the engine is not producing enough power, consider a big bore kit.
So if using Dr pulley sliders the doctor pulley logo would be on the side opposite of rotation....
Dr Pulley Slides are a great example of having the Closed End. So if we have the variator laying on a flat surface, as we place the Sliders into the Variator slot, the DR Pulley writing will face Anti-Clockwise.↪ watch from 7:40
Great tutorial. I have changed mine to molassi Multivar variator. The rollers are 8 gr. Feel the rpm is high before the bike move. Should I be looking into the clutch springs
Rpm should be high to allow a stronger engaging of the clutch. Can you compare it to how it was originally?
@@scooterstreetau How often should the rollers be changed. Feel now it has slowed down after 8mths
@@swimwithcoachraven1532 Worth checking every 3-5K
@@scooterstreetau originally rpm not high. Looking to build more torque
@@swimwithcoachraven1532 ok well you are on the right track, RPM higher with a later engagement of the clutch to boost from the start position. Tighter clutch springs will allow the rpm to build, so give the springs a go.
My new Yamaha NMax 155 scooter vibrates annoyingly at 10 KPH when accelerating. Can you tell me if changing the roller weights will fix it, and if I will need heavier or lighter rollers? If it matters, I’m riding a bike that may be made for the Philippines and lighter people, and I’m heavier than the average Filipino.
You really need to find out what is causing the issue. Changing the rollers most likely will not make a difference. Just and idea to check the rear pulley Clutch shoe condition. The vibration maybe engine bushes, a loose part of the engine. Get in there and have a good look making eliminations one by one😉
SO WHAT actually makes the scooter go faster the weight of the roller ?? the lighter the weight the faster the scooter can move ?
The scooter has a maximum physical limit for the transmission ( belt movement) it is about optimising the rpm and the progression of the belt to the top of the variator. Tuning the rollers to suit the engine is the art. Running with too light of a set of rollers will allow rpm but may limit or slow down the optimal gearing change to give the speed increase. Best to try for yourself, go for a roller 2 gram heavier than factory and then try a set 2 gram lighter, then you will know, wykyk.
So if you dumbed it down would it be heavier rollers make your scooter slower but stronger and lighter are faster and weaker
Just subscribed
Also are sliders better than rollers
Yes you can say that to have a very general understanding. Thanks for SUB🐰🙏
Hard to generalise but I would say this. " Starting from and making comparison too the factory rollers you will find: The heavier you go with the roller weight you will slow down the acceleration. The lighter you go, you will increase the engine RPM and accelerate the engine for a moment and then the speed will fail to increase due to the light weight of the roller." With a 50cc we 10% lighter on the rollers. with a 70cc we 10% heavier the rollers. So much more comes into play when you set up Upgraded cylinder with upgraded exhausts.
@@thefallenking7538 Rollers and sliders both slide, you will notice flat spots on the rollers due to this sliding action. Named rollers for their shape. Sliders benefit is they offer a larger surface area of slide and wear slower compared to the rollers if having the same composition. So most important thing is, material and weight. Go for it👌
Hi at the moment I've just got a stock Typhoon which is deristricted. My daily travel has a lot of hills involved and was woundering if getting lighter rollers could help with that?
Certainly you should trial some different sets of rollers, The stock usually has 7.5 gram so try the 6.5 g set and note the difference on the hills.
Do you know what kit will fit a 2022 Honda Navi 100cc Scooter. Thank you!!!
I am guessing the Navi follows the PCX transmission, The PCX 2021 variator from Malossi is 5118776. If you check the spare parts and confirm against the original sizes and dimensions of the Navi you may find they are the same.. Do the research first😁👌
Should I go heavier or lighter for higher top speed if I don’t care about acceleration
Leave the standard rollers in if you need top speed.
Tuning a variator is all about finding the optimal weight, this gives the highest RPM, the strongest pull and reaches the top speed. If you don't want to go through the task of tuning just try to fit 0.5 of a gram lighter on each roller than the original roller weight. This will give what is required with smallest effort.
What makes the more expensive "high performance" variator kits any different than the standard kits you can buy ?
They are developed to increase the effectiveness of the transmission by maintaining optimal RPM. With different weights the variator can be fine tuned. This can increase the acceleration and also top speed.
The ramp slot that the rollers are housed have a different angle, some kits have upgraded the size of the guides with smaller tolerances. Often the performance variator is cheaper than the OEM. Saying this, there are cases where the factory Variator will have the same performance as the aftermarket Variator.
Most scooter parts from China labeled high performance are just “cheap replacement” parts. It’s more important that your transmission is properly tuned to keep engine rpm in the power band. The physics is the same no matter how much you paid for your variator.
Hi ! Impressive video. I have a question . I have a sym hd 300 , polini variator 14g rollers and the blue hard contra, also free dna air filter . The manual says that at 8000rpm max h.power. the rpm has increased from before , and 0-100 very fast but then drop , and the max speed comes vary vary latter and the rpm gies to 8100-8200? What mod would you suggest in order to reduce the drop at higher speeds? And do you suggest a aftermarket muffer?
Thank you.. Try varying the roller weight, Go heavier and then slowly reduce weights, so you can see what the change makes on the road. The spring, try the original spring and then again varying the rollers.
@@scooterstreetau thanks. And what is your opinion about aftermarket exhaust??
@@christos5635 Aftermarket exhaust: Great sound, more noise awareness for drivers. At this cc it gives good mid-range power and can add to the top speed, you need the variator/transmission tuning and you have the variator.
Hello,
I just upgrade my artistic spec jog from 50cc to a 70cc kit. Wich set weight of rollers do you recommend me?. I have on the stock exhaust, I noticed to scooter is a little sluggish to get up and go.
Thank you
Test the rollers at 1 gram lower on each roller. Did you adjust the carby main jet?
Hello, i have a aprilia sr 50 2020 E4 with piaggio engine. The standard rollers on it are 7,2 or 7,5. I changed the rollers to 6,1 but it accelerates very slowly, like the engine revs a bit but i can reach max 45 50 km/ h and it takes a little bit more time than it took when i had the standard rollers
I still have the restrictions on it but without the variator restriction
The scooter is designed to go slow according to regulations, it needs to be derestricted in order to gain more power and top speed. Changing the rollers is one part of the puzzle but the CDI/ECU will need mods and also the carby and def. the exhaust.
@@Octavian17 See reply☝👇
I still don't understand the steps to try a suitable roller by combining light and heavy rollers. Please explain the steps, and what roller indicator is right for me. I weigh 172 pounds and the factory default rollers are 11 grams, the springs have been changed to 1000 rpm, but when I go up the hill my scooter struggles when I accelerate
Ok, When you have time to change and test ride you should begin. Basically all you do is start with 11gram rollers, mark the variator face with the black pen and fit 2000rpm clutch springs. Go for a test ride and note the performance. Go back to your garage and replace the rollers for 10gram and visually check to mark sure the pen mark has been rubbed away from the belt travelling to the top of the variator. Re-mark after each roll change and always check. repeat the same ride as the previous again noting the change from the first ride. The difference in the way the engine acclerates, holds speed and drops when throttle off shoud be noted. Find the best performing set of rollers weights for your setup. Once done you can experiment with hight tension Torque springs and clutch springs again note the effect each part has on the performance of your scoot. Make sublte changes for best performace.

Hi Marc, difficult to have an exact answer. Like all the other variator questions the best answer is to start at the factory rollers and reduce from there. There are instances where the roller weights are increased but usually lighter will be more effective. Trial and testing.
Thank you for the insight.
My pleasure!
what is the excellent combination of weight of of flyball if you want more torque because we leave on a mountanious area. i have only 110cc of scooter. thank you
You would nee higher rpm and a variator that is responsive to quick load changes. Increase the torque spring tension and adjust rollers as required.
I have a Wolf Blaze 2 150cc. What kind of rollers should I get to get faster take off and keep maximum speed? I’m in Florida and average speed is about 45 so I want to get to at least 50mph rather sooner. TIA. Stock scooter except carburetor
Measure and weigh the current ones and try a 5-10% less weight of the same dimension, Stiffer clutch springs will add to the result.
@@scooterstreetau will do. Thanks 😃😃
Hi do you sell or know where to buy as im in sydney i have my first scooter its a scarabeo 200ie 2012 what do you recommend for better take off and do i have to upgrade the jet needle.
Fit a Variator to the Scara, works realy well. We sell parts for Scara. 200.
I just purchased a 2019 metropolitan, how can I make this scoot to hit 45 mph and get there quickly? It's completely stock bought it with only 15 miles on the odometer. Currently it hits 37-38 mph with me weighing 205 lbs.
Is that a Honda? We found the variator is a good solution to revealing a little more power and speed.
Ask the local Honda dealer too..
Great video. Very well explained. Thanks
Thank you👍
Does it matter which way the rollers drop in, ( with the "brassy" side one way or the other ) ?
Yes, you need to make sure they all face the same direction, with the smooth (non beveled) side facing clockwise. Double check the direction with your manual. Also, I think my manual called them weights.
@@JB-xi2yv Good answer JB 👍
Good question! When rollers are manufactured the weighted insert slides into the outer shell. Some rollers have an end in which the weight enters and the shell has a capped end to stop the weight going all the way through the shell, this capped end is called the 'closed end' and should always face away from the direction of rotation when placed in the Variator. Other rollers are glued and do not have a closed end so it will not matter. So always look for the closed end when placing the rollers.
Yep that's what I thought, the closed or capped end , opposite the direction of rotation , correct??
So the " closed" or "capped" end opposite the direction of rotation...
Great video!! I have a question
I run a piaggio typhoon with 70cc kit
Main carb with 74 jet
Malossi exhaust
Malossi air filter
But the problem is that when I go to a big hill it is like the spring can’t change the transmission (I have factory heavy rollers and factory soft spring from 50cc) is it better to leave the rollers and take a harder spring ? Or is it going to put to much pressure on the belt? If I change the rollers with lighter is it going to lose grip on the belt ? (Sorry for my English ,I hope I am understandable)
Well Thank you😁 we appreciate the views and comments.. A few things, make sure the carby is tuned, the air-mix screw all the way in and then 1 single turn out, set and forget. Is the jet size large enough? Is it running lean? The factory rollers are 7.5. Try a 7.2 or 7 Gram set ensuring the belt is always reaching the outer. Diameter of the variator. I suggest this because it is easier to work out the solution by changing the rollers instead of the Torque spring. By the way make sure the clutch twist rotation is smooth and not stepped.
@@scooterstreetau
I have 6 gram rollers
I have some holes to the filter box also …
And the air screw is half open
I will try Malossi green spring in order to help it with the transmission….if it doesn’t change I will buy new even lighter rollers to try again. My plug color is brown
@@flawlessmusic8850 For variator testing , remove 2 rollers to see if it makes a difference, there are many ways to test with the parts that you already have, I am not to sure about holes in the airbox unless you have the carby tuned to suit.. too much air can lean the mix and the power is reduced and it bogs the engine under heavy throttle..
@@scooterstreetau

Maybe check the torque spring
4.6 is probably too light. Go back to standard rollers or only 1 gram lighter. Now get the carby jet correct first and then come back to the transmission.
Hi Scooter street! I recently bought a china 2stroke scooter. It had 4g rollers when i got it, they were worn, with flat spots. I replaced them with 6g rollers, it had poor acceleration and top speed then. Now i put in 5g rollers, it seems to have good performance now, but im afraid it is reving too high at high speed. It has leovince exaust on it and stock 50cc cylinder. Can scooters get damaged from reving too high? I dont know how much rpm is normal, no experience with scooters
No, it cant really rev too high so don't worry about high RPM. 2 stroke engines are high revving engines, a near standard scooter such as yours cant really over rev to the point of damage unless there is a serious mechanical issue. You should try the marking of the variator to see if the belt is reaching the top of the variator. Also a heavier torque spring will counter the heavier rollers. Do some trialling and come out with the best outcome for the transmission..
Can you put 2 light and 4 heavier in a hyper2 variatior, or only on exactly 180°
We suggest that you trial different weights to get the bet performance for your set up. Once you find this best performance weight, then find the total weight of all of the rollers and divided this total by 6. This is the weight that each roller should be. If an 8 roll variator then divide by 8.
What rollers do I install for highest top speed?
I have no firm answer. You must trial different weights to find this out for yourself. The standard rollers will give the highest top speed but may not allow the best acceleration. A slightly lighter set of rollers will also give the highest top speed and the acceleration will start to increase.. If you reduce the weight by small increments you will eventually find a weight that will no longer get you to the highest top speed (they will be too light to drive the variator to highest belt position). So you need to find the lighter set of rollers that increase the acceleration and also still provide the highest top speed. This will be the optimal set. At a guess try 12-15% less than standard.
Hi, I have taken off many variatiors, Im tryn to get the variator off of my prescott 50i gy6 and the nut will not come off, I tried my usual torque wrench that always works and my buddy came by with large set of socket wrench and he couldnt do it, have you had a situation where you cant get the variator off and what did you do? Id hate to not be able to upgrade this scooter TY again!!!
That sounds pretty frustrating! Not familiar with that particular make but the GY6 engines obviously all share a fair bit of commonality. I would recommend a rattle gun/torque driver with minimum 350-400Nm torque. In most cases you'll need a fair bit more torque to undo a factory nut than to retighten it. They make have used some thread lock in the factory as an anti-tamper, or it may just be corroded or stuck on. If a rattle gun still wont get it off, I'd recommend taking it to a mechanic.
Sorry, I still don't get what's the purpose of mixing different weights. Since the heavier weight are always going to go up the ramp faster from the centrifugal force.
Also, I don't really get the part how the weight of the roller affect the ride. I get that with heavier rollers it means it will go up the ramp quicker(lower engine rpm) and with the lighter ones it takes revving up the engine more to get the rollers to the edge. When the rollers get to the edge, the belt moves outwards, effectively increasing the gear so to speak, you'd have faster wheel rpm and less torque right? Or is it the other way? That the torque is highest when the rollers are up on the ramp?
Does that mean with lighter rollers you'll likely have more torque, better acceleration at lower to mid speed for instance say 20km/h -60km.and with heavier rollers youd have weaker acceleration at the same speed range?
The combined push from all of the weights changes the variator position. The best thing for you to do is to see it in action with a simple experiment.
Take your variator and weigh the factory rollers, now place a new set of rollers which is 50% of the original weight. Run a test ride and note the difference. Repeat this experiment with 50% heavier than original rollers and again make notes. The belt moves as the rollers move. YT search the variator in action and you can see this entire experiment.
Hi. Can you put more than one shim in?
Yes.
Hi do you need a longer drive belt used with a larger d.I.a. vari to allow for full shift and top speed. On a gy6 4t. 87mm.stock vari
Using a longer belt will help get you to a higher gear (top speed). You will be limited by the rear pulley, so use a bet that maximises the diameter of the smallest pulley. Do keep the same width on the belt, do not go wider..
When it comes to replacing the variator rollers then many mechs use grease on rollers & they say that it'll make scooter noise less.
But few of them strictly prohibits of using it as it's the dry clutch thus no grease is needed.
What is the correct method according to you in gearless scooter.
I've got a Honda Scooter that's causing vibrations when start accelerating it from 0 then after reaching 5miles per hour all vibrations disappears.
But at every stop & go, it's visor & body vibrates which is problematic in slow traffic.
Mech saying that variator rollers needs to be replaced & he's suggesting me to grease the new rollers before putting in.
It's a big confusion😢
What is correct is what you find the best outcome for you.
We never use grease in this area unless the variator is sealed and therefore requires grease.
Find out why the vibrations and correct this issue instead of a band aid fix. Again, find what is best for you my friend👍👍
@@scooterstreetau Thanks but what do you mean here by sealed.
Like when variator is stuck or tight?
@@abhimd3455 Some larger capacity scooters come with sealed variator, they are sealed with grease inside. The grease is inside the variator and captive by orings and seals so the grease does not venture out on to the belt and dry faces. Grease is also applied to the shaft and has an o'ring to keep the grease in the lubed section.
@@scooterstreetau Thanks you so much for clarification.
My Honda Activa 5g has 110cc engine & basically comes with an open variator without any grease as I may see when opened it for very first time.
Thanks again
Great video! looking forward to learn more with you. new sub also
Awesome, thank you! Appreciate the support👏
If i do this on my stock scooter does it go faster?
Lighter rollers may give better acceleration. but not too light.
what happens if you just shorten the the spacer? the hollow piece in the middle of it all. shouldnt it accomplish the same thing
🫢the take off will be terrible as the belt will ride higher on the variator face.
Im going to take 2 of the out and roll on 4 that should work
This is ok for a trail but don't leave it that way.
Just wondering, if the scooter is restricted will lighter weights allow it to get a higher top speed or will the scooter still restrict the speed?
If the restriction is the rollers, or the variator then yes. If the restriction is in the exhaust, then no.
@@scooterstreetau Do you still think it will be restricted if there both a restriction in the exhaust and the variator?

Try the 9 gram Malossi recommend, you may find it limits the initial rev. So move the a 7.5gram set. You need an exhaust for the Super 8 because they are not so super in their speed.
