Thanks so much for saving me a bundle of cash, first I drilled out rollers to make lighter, discovered I needed heavier, no problem thanks to your idea of filling with solder to my exact weight required. Truly brilliant, did not spend a cent and not need to wait for delivery. Also my rollers are not easily available in Australia.
perfect! just what I needed. I bought an overstored CVT that unfortunately uses the freak roller size 17x13.5mm. I got 3 sets of rollers with it, the heaviest set being just a bit too light. I'll try stuffing some tinfoil in them. Good thing I have a 0.01 gram scale at hand too :)
Great video! I have some 4 gram dr pulley sliders that I need to add solder to make them 7.5 grams. I noticed when you drove out the center brass piece it looked like it cut a ring of the nylon the size of the brass. I suppose the nylon is very thin in that area and the brass cannot be removed while keeping the nylon in tact. I would hate to damage a set of expensive sliders, but I need to add more weight than foil or epoxy will add.
ShareCraft It is thin there and I don't see much other way of easily removing the centers in them without that part getting knocked out. I'd look at it like this... if you need 7.5g sliders and only have 4g, they aren't of great value anyway short of trying to resell them.
Hi Sir, I have a question about the sliders, is necessary a longer belt in order to absorb the estra opening of the variator? Thanks in advance, I'm planning out 11.5 gr on my Agility RS125, original rollers are 14x18 x 13.5 gr. Do this will provide me better acceleration without top speed loose?
This video was so helpful man. Now i can mod my rollers to make them heavier so i can get more power. Im gonna chose the screw & aluminum paper method. Thanks again.
Thats why they thought of roller sets that are mainly used to determine the exact roller weight you'll need. Comes with a range of weights from like 5.5gr to 9.5gr and you can combine/swap those.
Those are nice, but what happens when they don't sell rollers/sliders that are just right for you if you rely on a credit card to do all of your tuning?
So if I add weight to my rollers my top speed will go up right. As I did put 1 gram of tin foil in them and it seem my speed went up by 1 mile per. Hour. My bike is a 50cc with a 50mm bbk and I picked up a NCY CLUTCH BELL helped a lot . My bike is so fast off the line but I want more speed. Thanks as you have helped me in the past . And I will be h hitting up your tip jar soon.
Heavier is not always faster. Too heavy and it will slow. Too light and it will slow. The real key is to tune so you are in the powerband when you want to be. A tach is an excellent CVT tuning tool.
When I use heat resistant epoxy. Is it safe to use it for a long time? Not just as test roller... I need a heavier set for my 2020 xciting s 400i. But nobody carries it here in Philippines. All they have is 10s n 11s and it's to light for my contract springs. Top end suffers a lot a much as 15kmh.
I've nearly always got modified rollers in my scoot. As long as whatever the filler is can hold up, doesn't damage the variator (keep it more narrow than the rest of the roller insert so it won't wear away at things) and doesn't come out, there should be no issue.
I had a problem with the aluminium foil method. Some became loose and fell out and got stuck between rollers and ramps. I think because i made them too "loose" by compressing the foil too much they moved around and eventuelly came out of some of the rollers center hole. Next attempt is to use leighter rollers as a base so i can use a bigger volume of alu foil in order to have it sit tigher. Or maybe go the longer but seemingly more secure and stable way of cutting a thread inside the roller and use a chopped up screw. Will update when i get new results.
Really appreciate.. I just want to know one thing..that is ... if I want to start with minimum acceleration to start rotate the wheel do I need to apply weight or make the rollers light ..? Which one I need to do..? In POC I wud like to convert petrol scooty to electric scooter.. So removed engine and mounted motor so now motor is rotating speed but CVT roller think is not starting untill motor is fully speed. I would to convert rollers that need to start when motor is minimal speed. Any help
Heavier weights would make the CVT start shifting earlier. Lighter weights make it shift later. So heavier for lower RPM, lighter for higher RPM. Could also be clutch related. Maybe you need softer clutch springs so the clutch engages earlier.
Less acceleration, use lighter weights. For the clutch question, you need much lighter clutch springs but you have another problem. The electric motor spins far slower than a petrol motor and with much less torque. It is not going to work well. You would be better off buying a properly engineered electric bike. E-bikes have direct drive electric motors built into the rear wheel. There is no clutch or drive belt, just a switch and a VFD. They are also much lighter than a petrol scooter.
I literally just made some. Id say the weight needs to balanced. Mine probably are or probably not will see. First time but i remembered seeing a vid u did on my way jome fton work while on the rapiddog with bbk an it revs so high an has 9g rollers
Definitely needs to be balanced weight placement. If you need really heavy weights, you may consider using a softer contra spring if you've got an aftermarket stiff spring in there.
i stuffed me rollers with some lead fishing weight very tightly. will i have any problem with the fishing weights to leave from they're place from variator shaking or something else?
Can't say for sure with fishing weights. The other methods conform to the inside shape of the roller and there isn't enough room for them to slide out.
@@unplannedtripz9301 Can't generalize. Lighter will increase RPM. Heavier will decrease RPM. Depends how the scoot is currently and where it should be.
This is a fantastic idea, does the density differences and placement abnormalities affect the stability of rotation, and would this make them unstable? I'm talking about rollers and not sliders however.
Unless you did something like filling a corner with solder and leaving the rest empty, I don't think it's sensitive enough to changes to matter. If you're packing aluminum foil in there, it's consistent enough. I've never had any trouble with it as long as you are careful to keep each weight equal.
I have thought about experimenting with this but only having one set of weights and no impact wrench, getting the clutch off was a problem and then if I had made a mistake no ride so.... Now I know, if I pick up another scooter I will be trying this!
Save up man. An impact wrench is worth every penny. I got a cheap one at Harbor Freight for $50 and an impact socket set at O'Reilly auto for $20. And I got a double sided 41mm and 39mm clutch nut socket for like $15 on eBay. No more struggling on nuts for me! :)
If that doesn't work I'm not sure. Some of mine squeal and I've never had much luck beyond the simple sanding. You could replace parts or just deal with it as long as the brakes function well.
+90GTVert "just deal with it as long as the brakes function well."....that is what i do when i don't what to disassemble all the stuff just to sand the pads .... :)
They're all different for multiple reasons. All 1500 springs are not equal, all setups aren't exactly the same, and preferences may vary. The best option in all cases is to go through a tuning process.
@@49ccscoot i have 4.5g weights by accident, the stock my scooter had was 8.6g and i would like to try out 11g too. Edit: Thank you for the quick reply! Love your videos!
Though its 7 years video, still variator/weight roller have not changed at all. new to CVT. if i understand correctly, one should choose a roller which maximized ones scooter peak power, in this case mine is at 7,000rpm on XMAX 250. what am not clear is the odometer on my xmax shows 8,800rpm as red line. The question to play around the roller weight to achieve full throttle at 6,800rpm or 8500rpm ?
Redline doesn't tell you where peak power is. You would be better off to use dyno graphs or manufacturer reported horsepower and torque peaks to help you decide what RPM to tune for. That's just a baseline. Then you would need to do some timed acceleration runs or other performance tests to find what actually works the best for your setup.
Hi, i need to know what setting can i do in the cvt to make the clutch engage at a lower rpm? My scooter needs an unusually high rpm before it starts to take off
Ah, awesome thanks. I recently had the clutch replaced with an aftermarket "racing" clutch. The springs were indeed much tighter than the original. Now i know why
i got those dr. rollers and they only lasted 800 miles , barely use the scooter , but took like 4 trips of 15 min , don't think is too much but, do you think they flattened due this? actually one was really bad and another regular but the scooter didn't give any sign or problem , i just opened to see how the rollers and var were doing since was a new hoca . by the way also one slider guide was broken but not totally..... this scooter reached in a good day 47mph and 39 mph with wind......i thought dr's rollers/sliders would be lasting longer time.....now i installed 6 gram dr sliders , which are ok, reaching 41mph (very smooth transition , i like that) proble is i don't know how log this sliders will last , i noticed there is a lot of white powder. contratrary to the use of the rollers showing very little of this powder and var and var guides looked like the first time they were installed.....
+marion ramirez I think your odometer is off if you took 4 15 minute trips and that was 800 miles. You were literally going 800MPH otherwise. Surprised the whole scooter didn't melt. :P I've had great luck with DrPulley sliders. I've only ever used their rollers in an over range pulley and that thing flattens everything I've tried in it prematurely, including the DrP rollers and sliders. I've got sliders here from Hoca and other variators that have 5,000+ miles on them. If you're flattening them out in 800 miles it's gotta be an issue in your CVT I'd think. Running too hot or the variator is rough or worn.
hahahaaha, no ,i was referrenig to the last trips i took , 15min one way 15min aprox (~30-40min) the other way....... :) . well regarding the hoca var i got it in march , is not supposed to be worn , is it? , i used to have the koso that lasted a little bit longer ( var guides keep breaking ) ,,,, so what i think fixed the problem with the guides was that i stopped buying crap from EBAY and got what i think the real parts , had no problems since i installed bando keblar (japan 18.1) and hoca var.....but well as i said i opened to inspect the cvt , and what i decribed previusly was a surprise (worn rollers ,broke var guide) because the thing was performing lovely ! , and weird thing is that there were no symptoms (low speed , hesitation , marble sounds etc..).... so today i opened the cvt because was trying to find the problem ,and i think i found it (hope so)...... i alwas mark with numbers the ramps and the rollers/sliders to check which one has problems , well i guess it worked :) ramp 1 and 2 (rollers 1 ,2) presented a rought finish so rollers 1,2 worn badly . number 3 was also worn but not too bad, ramp 3 presented also some bad finish,,,,so....i just finished the job with sand paper trying not to take a lot of the var...just smooth the ramp a little bit more,,,, ,im glad ramps are not damaged and var still good . so i will use it like that and see what happens...i read polini doens't like dr' s rollers/sliders , may be is the finishing that is bad....... also , regarding the hottenes , well i noticed the var changed color , you know like the clutch, i think is getting to hot with the sliders.... one more thing, i put polini guides and these ones are much much better than stock or koso, or the cheap black ones.... the ones hoca included with the var were good , in fact only one is damaged but not totally broken , with koso var once one of them was damaged the plate eat all the var's posts .....and bye bye var , guides, sliders, AND belt....... thanks for the feedback :)
Gotta be some serious friction there for the variator to experience "bluing" from heat. Maybe the belt is slipping (should be glazed on the edges and you will see black marks on the pulleys). For the Minarelli, the Hoca variators regularly break guides. A member of the forum extended the guides successfully to solve that issue. I haven't heard of the Hoca having issues with sliders and I use sliders in all of mine. My ramps do wear, but I get thousands of miles from them not hundreds.
i checked the belt and is not "shiny"and no marks, var is clean , i think im going to measure the band tomrw, and also there is almost nothing of black dust from the belt, it was very very clean. what im worry is about var warping due high temp. i never saw that even in teh cheap dhl ,koso and stock ones.....ramps presented almost not wear , i think i opened the cvt on time , because as i told you with the other ones , once one of the rollers is in bare cooper bye bye to all the system,,,, i also didn't know the ebay belts (gates,bando ,and a "japanese brand ") were ALL FAKES , by now ,if alive, one of these belts from ebay will be a mess inside the cvt full of black dust ( which i had to clean every 5 or 6 days) . can you tell me ~ time of life of these hoca guides, they looked pretty good, are not even worn (only thing is the one broken of course). i used to open the cvt every time i returned from every ride because i was worry something breaks , it is a nightmare when you don't trust equipment !!!! i have dr's guides too , but i don't trust them i got my first set and were broken badly in my first test ride...... nice new videos by the way.. :) i had the valve identification size problem , not anymore.....
For me, how long the guides last depends on how the variator is setup and if I push to top speed. If the variator can open far enough that the ramp and guides are making minimal contact with the variator, I can break them first time out. If it'setup so half or more of the guide is in cotnact with the variator, they last a while.
Heavier rollers decrease RPM. That's their direct effect. Could be bad, could be good. Depends on the setup. This is a tuning trick to save some money while figuring it out. Stock scooter with heavier rollers will prob run worse, because it will rev too low.
Hey, I have a kymco agility city 50cc moped with all stock parts. I'm finding that it really lacks acceleration but after a while reaches top speeds of nrly 40mph. what would you recommend doing to gain acceleration? thanks for your or anyone's help.
Trying lighter rollers and possibly stiffer clutch springs may get it going better. www.49ccscoot.com/faq/whatweight.html www.49ccscoot.com/faq/clutchsprings.html
What is your expirience on clutch springs, i need more take off speed, should i do stiffer or softer springs, i think softer the springs are better the start is.
You need to find the right ones for each application. Stiffer springs raise the engagement RPM, but if you go too stiff the belt will start moving and then you lose the best ratio for a strong takeoff before the clutch ever engages. Watch the belt with each spring swap, and try some very short timed runs if you can't tell for sure any other way which springs are giving you the best launch.
The total amount of all your roller weights added together is what set your transmission take off and top speed is way better not to mix and match different weight rollers
Decreasing RPM. When I had some basically sport level 96-110cc Minarelli clone builds, I couldn't buy sliders heavy enough to keep RPM where it needed to be so I had to modify them.
@@eternalrage1085 Most of the time you aren't going to get a specific RPM at all times while full throttle, so if you can keep it between TQ and HP peaks that's great. Best way to know is to test. For example, I prefer strong acceleration 0-60 or 1/8 mile so I test different rollers and see which gives me the quickest times. If you are after top speed instead, see what makes you go faster.
No idea what a g6 vac s is. Weigh what you have and adjust accordingly. If you need more revs, go a little lighter. If you need less RPM, go a little heavier.
The simple answer is that heavier weights lower RPM and lighter weights raise RPM. The goal for performance would be to keep within peak power RPM range as much as possible.
Hey what weight it's better if i want to do wheelies easily I need to use light weights or heavy ? I have a Tao Tao 2014 50cc to 100cc I just want to give to the bike a little bit more power and do wheelies easier thanks if you answer me o somebody else
Standard weights in my 50cc 2stroke are 7.5grams i want more top end speed whats best rollers for this plz ???? Take off is good enuff just want more speed on straights
More accurately, I'd say more weight means lower RPM. If you happen to make more power at lower RPM than currently tuned; then more weight means more power. On the flip side, if you have more torque, you do tend to need heavier weights.
Thanks for your videos, you really know your stuff!! I have a question about roller weights and metal tubing. I saw you sub steel for aluminum on some weights to gain weight. I immediately thought, "Why could you not sub bare tubing for the coated weights altogether?" So now I ask you the same. Providing the weight were correct for any given purpose, why would one not want to use bare rod or bare tubing for roller weights?
OK, so the weights ARE expected to wear. I figured there had to be a reason that nobody had come out with weights that didn't wear out and have to be continuously replaced. Have been forced by circumstance to commence repairs on 4 short-case 50cc Sunny/H.B. scooters that have been on the back-burner for some time, and since these are not my strength as far as knowledge goes, I am trying to find ways to simplify repairs and save me money at the same time, so I may be overthinking this a bit. Thanks for the speedy reply!!
Rollers will flat spot at some point. Sometimes it takes a long time, sometimes it doesn't. Depends on the rollers and the application. DrPulley sliders are shaped different and they have held up very well for me. Most of the times that I have had them wear it was because of a CVT failure or something major, rather than everyday use. They may also improve performance a little over rollers because of their design.
The aluminium foil is actually clever, I wish we would've thought of that back in the day. The other methods are crap imo. Tapping, drilling, man it's just not worth it... Just get a few sets not farther apart than 2,0gr from eachother, and the foil technique should pinpoint the exact weight you need to order next time.
I keep wanting to hear what the different weights will do... I can imagine a heavier weight will make the sprocket change shape faster....and the converse is true for lighter. So if you want to hold a "low" gear for a longer period of time for acceleration...the lighter you go... the opposite again...for well...the opposite to occur.
Short answer; the right ones. :P The problem is, the right ones are different for each setup. Gotta do some tuning. www.49ccscoot.com/faq/whatweight.html
Depends what it needs. Lighter raises RPM and heavier lowers RPM. Either way can make it slower if you go too far. The idea is to adjust so the CVT keeps the engine in it's powerband.
I havw a 22 Honda Air Blade , it came with 16 gram rollers ( filippine flyballs ) , I put in 20 gram rollers oh boy what a difference and Honda parts said they would not work , he was very wrong . I see I can change the weight . So , I get sliders as heavy as 20 gram , if not , no problem . Press out the 20's from the rollers , put them in the freezer for a day . Take one out and it should slip in easy . Now I need to find some sliders .
The ID of the rollers and sliders may be different. You will also need to check the weight if they do fit. It's not likely to be right on the spec of the rollers that the inserts come from.
@@49ccscoot Weight is a concern for sure as out of balance can cause problems . If the roller weight is the same as a slider . Before in stall the roller weight , weigh each and correct if one is more heavy than the other . I have 20 gram rollers now with no problems so it should not be an issue .
Subscribe to your Channel I've been using the aluminum foil method for quite a while just did that on the girlfriends 49cc me dr. Pulley 12.5 I also had Tech pulley which seemed to me I had more low end really didn't see that much on the top so I just went back to what I know enjoy your videos appreciate you
I saw the TechPulley Flying Rollers advertised as the latest and greatest quite a while ago by a vendor. Then I never really heard anything else about them or saw anyone using them. Kinda figured they didn't live up to the hype and never tried them.
I use rollers with foil in them in my 103cc 2T. It does stuff like 750 miles in a weekend sometimes. No problem with the rollers. Actual test roller kits worry me much more. Those things are often cheap plastic and melt flat spots in them in no time.
90GTVert thanks bro. I just made the one's with the foil this morning. Im not sure how will they last my plan was to use them as a test rollers only , but if they can endure it great!
Hi bro i have 155cc scooter with max torque of 13.8 N.m @ 6,250 rpm and max power of 11.1kW / 8,000 rpm. What is the best roller weight to have better top speed??
Wear and loss of compression would be major factors. Any sort of issues down the line could make it seem like the engine was less powerful as well. Things like clutch transmission issues for example.
I see some videos about this, but what for? Could you explain that? what happens in the whole system with heavier rollers, and lighter rollers? Is there a bad design from source, so we need to change them? What I think, a heavier roller will amke the pulley to close faster, this is at lower revolutions, so it is like going from first to third very fast, this is the moto is slow at the start, at the end it is the same becasue full speed is only by the ratio of the pulleys, so there is no change (no more speed). With lighter rollers, you have a long first with much more acceleration of the motor (more rpms), not of the moto movement. To keep max speed may be, lets say you need 8000 rpm with lighter rollers, while with heavier rollers you need 6000 rpm. That is ok but not advantage, becasue at 6000 rpm, the scooter speed will be slower too, so at then end at 8000 rpm the speed will be the same, with lighter or heavier rollers.
+Avenida Gez It sound like you already understand what's happening. In even more simple terms, lighter for more revs, heavier for less, and tune to stay in the powerband as much as possible for best performance.
@@jerryplayer7850 If they're all even weight, it shouldn't cause vibration. Double check that every one is close. Try to get within 0.1g for all weights. Also make sure you didn't leave any sharp edges that could catch on anything.
+Super Mario Plush Bros 1 I am a fan on sliders. In my experience, they have far outlasted rollers in most cases. The only variator I have that will eat sliders and rollers about the same is the Malossi over range. Otherwise, sliders last a very long time for me. I mostly use DRPulley, but even a set of cheap sliders I had did very well.

I've nearly always got modified rollers in my scoot. As long as whatever the filler is can hold up, doesn't damage the variator (keep it more narrow than the rest of the roller insert so it won't wear away at things) and doesn't come out, there should be no issue.
These videos are great!
1 question. If I put aluminum foil into roller...how I will be sure that it will not come out ?.
I believe that it will come out in variator
If it's hammered in like shown, it has been fine for me. It turns into a hard packed puck.
I had a problem with the aluminium foil method. Some became loose and fell out and got stuck between rollers and ramps.
I think because i made them too "loose" by compressing the foil too much they moved around and eventuelly came out of some of the rollers center hole.
Next attempt is to use leighter rollers as a base so i can use a bigger volume of alu foil in order to have it sit tigher.
Or maybe go the longer but seemingly more secure and stable way of cutting a thread inside the roller and use a chopped up screw.
Will update when i get new results.
I've been using foil for years. Just used foil in a scoot with a 30HP racing engine without trouble.
Really appreciate..
I just want to know one thing..that is ...
if I want to start with minimum acceleration to start rotate the wheel do I need to apply weight or make the rollers light ..?
Which one I need to do..?
In POC I wud like to convert petrol scooty to electric scooter..
So removed engine and mounted motor so now motor is rotating speed but CVT roller think is not starting untill motor is fully speed.
I would to convert rollers that need to start when motor is minimal speed.
Any help
Heavier weights would make the CVT start shifting earlier. Lighter weights make it shift later. So heavier for lower RPM, lighter for higher RPM. Could also be clutch related. Maybe you need softer clutch springs so the clutch engages earlier.
Less acceleration, use lighter weights. For the clutch question, you need much lighter clutch springs but you have another problem. The electric motor spins far slower than a petrol motor and with much less torque. It is not going to work well.
You would be better off buying a properly engineered electric bike. E-bikes have direct drive electric motors built into the rear wheel. There is no clutch or drive belt, just a switch and a VFD. They are also much lighter than a petrol scooter.
Hi can I know what's the purpose for adding weight on the roller?
Very useful video .Thanks
Foil worked great thanks! Now i know what weights to buy 👍
Excelente your vídeo. Tankyou
I literally just made some. Id say the weight needs to balanced. Mine probably are or probably not will see. First time but i remembered seeing a vid u did on my way jome fton work while on the rapiddog with bbk an it revs so high an has 9g rollers
Definitely needs to be balanced weight placement. If you need really heavy weights, you may consider using a softer contra spring if you've got an aftermarket stiff spring in there.
I melt and cast lead for bullets and fishing weights , I am going to use your solder method but with lead.
i stuffed me rollers with some lead fishing weight very tightly. will i have any problem with the fishing weights to leave from they're place from variator shaking or something else?
Can't say for sure with fishing weights. The other methods conform to the inside shape of the roller and there isn't enough room for them to slide out.
I never seen before anything like this 👍
I want to know that any difference in performance after modification?
The difference in performance is the same as if you bought different rollers/sliders. This is just a different way to go about changing weight.
For better mileage & top end lighter roller or heavy roller ?
@@unplannedtripz9301 Can't generalize. Lighter will increase RPM. Heavier will decrease RPM. Depends how the scoot is currently and where it should be.
Led pellet with JB weld probably works as well. 😎
extremely well made video!!!
Thanks!
This is a fantastic idea, does the density differences and placement abnormalities affect the stability of rotation, and would this make them unstable? I'm talking about rollers and not sliders however.
Unless you did something like filling a corner with solder and leaving the rest empty, I don't think it's sensitive enough to changes to matter. If you're packing aluminum foil in there, it's consistent enough. I've never had any trouble with it as long as you are careful to keep each weight equal.
I have thought about experimenting with this but only having one set of weights and no impact wrench, getting the clutch off was a problem and then if I had made a mistake no ride so.... Now I know, if I pick up another scooter I will be trying this!
Save up man. An impact wrench is worth every penny. I got a cheap one at Harbor Freight for $50 and an impact socket set at O'Reilly auto for $20. And I got a double sided 41mm and 39mm clutch nut socket for like $15 on eBay. No more struggling on nuts for me! :)

hi what is the better flyball combination for 1500rpm center and clutch spring with stock carb and 50mm bore?
They're all different for multiple reasons. All 1500 springs are not equal, all setups aren't exactly the same, and preferences may vary. The best option in all cases is to go through a tuning process.
@@49ccscoot but it should be 2 different weights high and low or i can use 6 same flyball weights?
@@ochieev3165 They can be all the same. Alternating weights is used to make it easier to tune, so you don't have to have so many sets of weights.
Oh ok thanks bro

Solder is the extreme because it's such a big change. It worked for me though. Most will do OK with just using aluminum foil or making inserts.

for the video everone, keep up the great work.
Though its 7 years video, still variator/weight roller have not changed at all. new to CVT. if i understand correctly, one should choose a roller which maximized ones scooter peak power, in this case mine is at 7,000rpm on XMAX 250. what am not clear is the odometer on my xmax shows 8,800rpm as red line. The question to play around the roller weight to achieve full throttle at 6,800rpm or 8500rpm ?
Redline doesn't tell you where peak power is. You would be better off to use dyno graphs or manufacturer reported horsepower and torque peaks to help you decide what RPM to tune for. That's just a baseline. Then you would need to do some timed acceleration runs or other performance tests to find what actually works the best for your setup.
Hi, i need to know what setting can i do in the cvt to make the clutch engage at a lower rpm? My scooter needs an unusually high rpm before it starts to take off
Softer clutch springs is generally what you'd use to lower clutch engagement RPM. Could also be a worn belt.
Ah, awesome thanks. I recently had the clutch replaced with an aftermarket "racing" clutch. The springs were indeed much tighter than the original. Now i know why
i got those dr. rollers and they only lasted 800 miles , barely use the scooter , but took like 4 trips of 15 min , don't think is too much but, do you think they flattened due this? actually one was really bad and another regular but the scooter didn't give any sign or problem , i just opened to see how the rollers and var were doing since was a new hoca . by the way also one slider guide was broken but not totally..... this scooter reached in a good day 47mph and 39 mph with wind......i thought dr's rollers/sliders would be lasting longer time.....now i installed 6 gram dr sliders , which are ok, reaching 41mph (very smooth transition , i like that) proble is i don't know how log this sliders will last , i noticed there is a lot of white powder. contratrary to the use of the rollers showing very little of this powder and var and var guides looked like the first time they were installed.....
+marion ramirez I think your odometer is off if you took 4 15 minute trips and that was 800 miles. You were literally going 800MPH otherwise. Surprised the whole scooter didn't melt. :P
I've had great luck with DrPulley sliders. I've only ever used their rollers in an over range pulley and that thing flattens everything I've tried in it prematurely, including the DrP rollers and sliders. I've got sliders here from Hoca and other variators that have 5,000+ miles on them. If you're flattening them out in 800 miles it's gotta be an issue in your CVT I'd think. Running too hot or the variator is rough or worn.
hahahaaha, no ,i was referrenig to the last trips i took , 15min one way 15min aprox (~30-40min) the other way....... :) . well regarding the hoca var i got it in march , is not supposed to be worn , is it? , i used to have the koso that lasted a little bit longer ( var guides keep breaking ) ,,,,
so what i think fixed the problem with the guides was that i stopped buying crap from EBAY and got what i think the real parts , had no problems since i installed bando keblar (japan 18.1) and hoca var.....but well as i said i opened to inspect the cvt , and what i decribed previusly was a surprise (worn rollers ,broke var guide) because the thing was performing lovely ! , and weird thing is that there were no symptoms (low speed , hesitation , marble sounds etc..)....
so today i opened the cvt because was trying to find the problem ,and i think i found it (hope so)...... i alwas mark with numbers the ramps and the rollers/sliders to check which one has problems , well i guess it worked :) ramp 1 and 2 (rollers 1 ,2) presented a rought finish so rollers 1,2 worn badly . number 3 was also worn but not too bad, ramp 3 presented also some bad finish,,,,so....i just finished the job with sand paper trying not to take a lot of the var...just smooth the ramp a little bit more,,,,
,im glad ramps are not damaged and var still good . so i will use it like that and see what happens...i read polini doens't like dr' s rollers/sliders , may be is the finishing that is bad.......
also , regarding the hottenes , well i noticed the var changed color , you know like the clutch, i think is getting to hot with the sliders....
one more thing, i put polini guides and these ones are much much better than stock or koso, or the cheap black ones.... the ones hoca included with the var were good , in fact only one is damaged but not totally broken , with koso var once one of them was damaged the plate eat all the var's posts .....and bye bye var , guides, sliders, AND belt.......
thanks for the feedback :)
Gotta be some serious friction there for the variator to experience "bluing" from heat. Maybe the belt is slipping (should be glazed on the edges and you will see black marks on the pulleys). For the Minarelli, the Hoca variators regularly break guides. A member of the forum extended the guides successfully to solve that issue. I haven't heard of the Hoca having issues with sliders and I use sliders in all of mine. My ramps do wear, but I get thousands of miles from them not hundreds.
i checked the belt and is not "shiny"and no marks, var is clean , i think im going to measure the band tomrw, and also there is almost nothing of black dust from the belt, it was very very clean. what im worry is about var warping due high temp. i never saw that even in teh cheap dhl ,koso and stock ones.....ramps presented almost not wear ,
i think i opened the cvt on time , because as i told you with the other ones , once one of the rollers is in bare cooper bye bye to all the system,,,, i also didn't know the ebay belts (gates,bando ,and a "japanese brand ") were ALL FAKES , by now ,if alive, one of these belts from ebay will be a mess inside the cvt full of black dust ( which i had to clean every 5 or 6 days) .
can you tell me ~ time of life of these hoca guides, they looked pretty good, are not even worn (only thing is the one broken of course).
i used to open the cvt every time i returned from every ride because i was worry something breaks , it is a nightmare when you don't trust equipment !!!!
i have dr's guides too , but i don't trust them i got my first set and were broken badly in my first test ride......
nice new videos by the way.. :) i had the valve identification size problem , not anymore.....
For me, how long the guides last depends on how the variator is setup and if I push to top speed. If the variator can open far enough that the ramp and guides are making minimal contact with the variator, I can break them first time out. If it'setup so half or more of the guide is in cotnact with the variator, they last a while.
Can i use larger diameter roller weights? My stock roller is 19x17mm . Can i use 20x17mm?
You could try. It may help on the top end, but it may hurt your low speed performance. Larger rollers may not let the variator open all the way.
What will be happen if we will use heavy rollers instead of light weight stock roller.... Please tell me
Heavier rollers decrease RPM. That's their direct effect. Could be bad, could be good. Depends on the setup. This is a tuning trick to save some money while figuring it out. Stock scooter with heavier rollers will prob run worse, because it will rev too low.
Hey, I have a kymco agility city 50cc moped with all stock parts. I'm finding that it really lacks acceleration but after a while reaches top speeds of nrly 40mph. what would you recommend doing to gain acceleration? thanks for your or anyone's help.
Trying lighter rollers and possibly stiffer clutch springs may get it going better.

90GTVert thanks man
What is your expirience on clutch springs, i need more take off speed, should i do stiffer or softer springs, i think softer the springs are better the start is.
You need to find the right ones for each application. Stiffer springs raise the engagement RPM, but if you go too stiff the belt will start moving and then you lose the best ratio for a strong takeoff before the clutch ever engages. Watch the belt with each spring swap, and try some very short timed runs if you can't tell for sure any other way which springs are giving you the best launch.
thank you very much!
I have a question. What does 3 lights 4.3g and 3 heavy 6.0g rollers do? what it makes differents?
Does pretty much the same thing as all 5.15g weights.
The total amount of all your roller weights added together is what set your transmission take off and top speed is way better not to mix and match different weight rollers
4.3 x 3 = 12.9
6.0 x 3 = 18.0
30.9 total, 5.15 average
why would you want a heavier roller? i mean what is the pratical application or advantage of a heavier roller?
Decreasing RPM. When I had some basically sport level 96-110cc Minarelli clone builds, I couldn't buy sliders heavy enough to keep RPM where it needed to be so I had to modify them.
@@49ccscoot what should be the desired RPM? Is it where the maximum torque of the engine is? Or hp?
@@eternalrage1085 Most of the time you aren't going to get a specific RPM at all times while full throttle, so if you can keep it between TQ and HP peaks that's great. Best way to know is to test. For example, I prefer strong acceleration 0-60 or 1/8 mile so I test different rollers and see which gives me the quickest times. If you are after top speed instead, see what makes you go faster.
light and heavy marbles which release faster?
lighter weights will make it rev higher because they can't overcome the force of the contra spring at lower RPM as well as heavy weights can.

Awesome methods!! Thanks!!
What will be the effect of making the roller weights heavier or lighter? Sorry for my ignorace
Heavy weights decrease RPM and lighter weights increase RPM.
what changing weight achieves and how or why?
The simple answer is that heavier weights lower RPM and lighter weights raise RPM. The goal for performance would be to keep within peak power RPM range as much as possible.

Usually lighter weights if wheelies are all that you want.
Standard weights in my 50cc 2stroke are 7.5grams i want more top end speed whats best rollers for this plz ???? Take off is good enuff just want more speed on straights
More weight in rollers means , more power ?
More accurately, I'd say more weight means lower RPM. If you happen to make more power at lower RPM than currently tuned; then more weight means more power. On the flip side, if you have more torque, you do tend to need heavier weights.
How would you lower the shifting rpm? Increase, or decrease weight?
Increase weight.
Thanks for your videos, you really know your stuff!!
I have a question about roller weights and metal tubing. I saw you sub steel for aluminum on some weights to gain weight. I immediately thought, "Why could you not sub bare tubing for the coated weights altogether?" So now I ask you the same. Providing the weight were correct for any given purpose, why would one not want to use bare rod or bare tubing for roller weights?
It may work alright, but I'd be concerned that you could wear the variator instead of the weights wearing.
OK, so the weights ARE expected to wear. I figured there had to be a reason that nobody had come out with weights that didn't wear out and have to be continuously replaced. Have been forced by circumstance to commence repairs on 4 short-case 50cc Sunny/H.B. scooters that have been on the back-burner for some time, and since these are not my strength as far as knowledge goes, I am trying to find ways to simplify repairs and save me money at the same time, so I may be overthinking this a bit. Thanks for the speedy reply!!
Rollers will flat spot at some point. Sometimes it takes a long time, sometimes it doesn't. Depends on the rollers and the application. DrPulley sliders are shaped different and they have held up very well for me. Most of the times that I have had them wear it was because of a CVT failure or something major, rather than everyday use. They may also improve performance a little over rollers because of their design.
The flat spots begin because the variator gets hot enough to melt the roller weight shell....after you ride then park you're scooter..
The aluminium foil is actually clever, I wish we would've thought of that back in the day. The other methods are crap imo. Tapping, drilling, man it's just not worth it... Just get a few sets not farther apart than 2,0gr from eachother, and the foil technique should pinpoint the exact weight you need to order next time.
I keep wanting to hear what the different weights will do... I can imagine a heavier weight will make the sprocket change shape faster....and the converse is true for lighter. So if you want to hold a "low" gear for a longer period of time for acceleration...the lighter you go... the opposite again...for well...the opposite to occur.

Which weight make the bike go faster light or heavy weight?

@@49ccscoot Thank you so much
I see some videos about this, but what for? Could you explain that? what happens in the whole system with heavier rollers, and lighter rollers? Is there a bad design from source, so we need to change them? What I think, a heavier roller will amke the pulley to close faster, this is at lower revolutions, so it is like going from first to third very fast, this is the moto is slow at the start, at the end it is the same becasue full speed is only by the ratio of the pulleys, so there is no change (no more speed). With lighter rollers, you have a long first with much more acceleration of the motor (more rpms), not of the moto movement. To keep max speed may be, lets say you need 8000 rpm with lighter rollers, while with heavier rollers you need 6000 rpm. That is ok but not advantage, becasue at 6000 rpm, the scooter speed will be slower too, so at then end at 8000 rpm the speed will be the same, with lighter or heavier rollers.
+Avenida Gez It sound like you already understand what's happening. In even more simple terms, lighter for more revs, heavier for less, and tune to stay in the powerband as much as possible for best performance.
