I've put just about 12k miles on my 4t 2014 Yamaha Zuma. I'm still a little green to do a full big bore kit, so I'm doing a Malossi clutch/variator job this weekend. Your videos (amongst many others) have been a great instruction. Huge thanks sir!
Put my racing vario on today and and am over revving up to about 10mph then she takes off and the revs drop, i now thanks to you guys have an understanding and 3 sets of roller weights that i shall configure till my 125 dont over rev then kick in at 10mph, very happy with the 10 to 65pmh though!!
Great video I'm not a mechanic but this video helped me so much I have a scooter in the belt broke at first I had thought all I had to do was put it on and that's it well I put it on and it didn't work when I saw the video and went step by step now it's up and running you save me so much money doing it myself thank you great job
Hi Kevin. Most people, like you, are highly appreciative, but there will always be a small number of ungrateful lowlifes out there. Many are trolls, jealous because they cannot produce a good video, or just get off on being miserable. Every channel has them. :-)
WOW.... U R AMAZING! I am NOT MECHANICALLY INCLINED; you not only METICULOUSLY gave instructions, but you have given me the CONFIDENCE to do this myself and $AVE CA$H on paying a mechanic. THANK YOU KINDLY ❣
I love the video. Thanks for posting. I notice your belt is inside out from mine. I asked about this and was told the drive comes from the grip of the tiny perimeter of the belt and was wondering if your belt was different or you flipped on purpose? If you flipped was there a noticeable change?

Why did you not show using that strap method to remove the 19mm bolt?? And using rods in the plastic fan to secure it can easily break the fan. I must just have one hell of a tight nut on mine because I am buying an impact wrench.

Very well shown and explained!! Having not long got involved with scooters again and new gy6 engine! Your vids are very informative and easy to follow up on! Thanks!; hopefully see a vid about 125cc racing variators and whether or not to run standard cdi units with the new vario or whether it is best to focus on your ramp and weights!! IE; what weights work best for different riding needs!! Thanks for the ones i have seen!! Great!!
Great Video, I have the symptoms of noise coming from the CVT cover. However my 2014 150cc Tao Tao also shakes and stalls out when I come to a complete stop. I have cleaned the carb, checked valve clearances, cleaned fuel filter, messed with the idle screw, and yet it still shakes and dies out when stopping. It was running fine until about 2 weeks ago and then all of the sudden I am having this issue of stopping and having it stall out. Do you think changing the rollers out may stop me from having this issue?
good channel and simple instructions but I still had to use a impact wrench ..the one I used was Ryobi battery operated ..and did not use a oil wrench to hold variator ..with a new belt you need .impact I tried this way on this channel and did not work to will ..new belts don't go on to easy but once stretched belt is easy ..I have a sundiro 125 cc scooter ..
Scott Milnes just find someone who has a very powerful drill, preferably a corded one that plugs directly into a socket, they are always powerful enough and u don't even have to hold it from spinning, it'll spin a little but the nut will come off so fast it'll barely have time to spin, if u don't know anyone who has a high powered impact driver u can rent them cheap at places like home depot and free and some auto parts stores

I hope this makes my trike 50cc scooter go faster I’d at least like to go 50 but I finally changed it to a 100cc jug and piston but it smokes because it’s to powerful for the 50cc head so I have to get a head and rocker arms and exhaust and it should stop smoking. But if it doesn’t I’m going to save and get the complete 80cc kit with everything right down to spacers and gaskets oh by the way it does 71 mph now but it’s smoking bad and it is almost new so I’m not going tear it up just going to get the right stuff and do it right.
Thumbs up, great video. I just bought a 2016 Tao Tao Quantum Tour 150. Any idea what size stock rollers comes with the scooter. I too am thinking 15g rollers would be best for my riding style.
Cajun Kevin my 2016 TaoTao Motors 150 came with 12g rollers which I have already changed 215s I seem to get a better overall performance out of the 15s
Do you know what direction the roller weights are supposed to be in? I've had only one time the metal slipped out from the roller, it damaged the variator, I heard something about your supposed to put the more sealed off side wall in a certain direction. Never heard of the specifics. PST subscribed!

My 125 scoot is flat out at 45mph when it should be able to get 50-55mph, so what roller weights do I need to restore the scoots top speed? Thanks in advance.
Hello i need some help please im confused,i have a 125 qingqi 10D with 7000 km it looks same as yours the variator. now recently i change the weight rollers because they were very worn,my question is i have 2 spacers one go with the big lock nut and the other one before the fan i just wonder if i really need those because i after i change the rollers i have some weird sounds and im thinking they are comming from these 2 spacers.i see you dont have those spacers. thank you
Hello, I have a gy6 and have just changed the belt (very shredded) but wasnt able to take off the clutch or variator. case cover back on start up good, I usually idle high tire spinning ..but now seems to be taking off in like a low gear.... and eventually does get up to speed. just takes a while.. like counting seconds rather than gas and take off fast. is this similar? . any help would be appreciated.thank you
Hi Mike. Sounds like a lot of debris needs to be cleaned up. I suggest borrowing an impact wrench and removing the variator and clutch for easy cleaning. Thanks for watching!
Just recently bought a second hand sunl 150cc atv.when taking off I have to rev fairly high before it engages...other then that the motor runs awesome .in your opinion what would be the issue..thanks in advance.
@electronicsNmore Is this theory correct that after applying grease on round rollers in variator they don't able to roll properly and tends to slide which cause irregular flat sides. And these irregular flat sides causes vibrations on certain speed? Is it right?
my sons lexmoto dart 125 ,GY6 I think is sometimes not engaging drive when revved ,its only got 5k ,tips on were to look first would be a great help ,cheers.
Glad you thought so Steve! Be sure to check out my extensive video playlists for other great videos of interest to you, rate thumbs up, and share my channel with all your friends.
Do not apply thread lock on nut .we have been playing with cvt drives for years never needed to use thread lock never had one come loose. Manufacturer does not have this on procedure on varatior replacement. Why are you recommending this additional step??
Randall Highsmith If you don't have an impact wrench, then I highly suggest using medium strength thread locker. I used it for years with no problems. If you don't want to use it, then dont.
Wait so are you supposed to hold onto the variator with your hands while you use the impact wrench? That sounds hella dangerous am I misunderstanding you?
All depends on the terrain, or if you want good fuel economy. 14-15gm is ideal for hilly areas, and 18gm is good for flat areas where fuel economy and highest top end speed is desired.
my 150cc the gear is engaging at idle, almost dropped on side when I started it up and wasn't on it. Now when I stop at lights and such, it still wants to engage and I have to literally hold it back. I never worked on these but I'm going to remove the cover to see what's going on... any suggestions on what to look for??
Is it right to apply greese/wax on rollers and in variator for smooth spinning of rollers in variator? Or will it make more issues after some time like dust attraction, vibrations etc ?
@@electronicsNmore Is this theory also correct that after applying grease on round rollers they don't able to roll properly and tends to slide which cause irregular flat sides. And these irregular flat sides causes vibrations on certain speed? Is it right?
I hear a loud rattling but only when the engine is revving down. Like as I let off the throttle as I approach a stop sign. The sound is not present when accelerating or idling, only when slowing down or coasting. Could this be caused by worn rollers? I initially thought I had a loose bolt somewhere that was jiggling but I can't find one anywhere.
wont 18g rollers be terrible on take off on a 50cc gy6 139qmb? mine has 5g rollers in in and it takes off ok but i ordered 4 g rollers for more take off.. i installed a new DLH racing variator and staggered my weights 5g 7g 5g 7g 5g 7g to get an over all average of 6g variation and it is slower on take off now so im going back to the 5g rollers until my 4g rollers come in a couple days.. im also going to install a 1500 rpm yellow racing clutch spring to help on launch.. im trying to find the best possible setup for 0 `to 30mph and pull a hill at a steady 20mph or better if possible.. i only weigh 170lbs .. what is your recomendation?
Lower weight rollers will cause the engine to rev a lot more before you start to move, and cause the rpm to be much higher at top speed. For best fuel economy, a heavier roller is best, but you lose speed on take off.
What about those people putting 18 g rollers in? I live in the mountains with lots of hills.. so would you put 4G rollers or 18g? I'm think of the 4G cause 0 to 35 is all that really matters as long as it can steady pull me up a hill doing at least 20 to 25..your thoughts on roller weights and driving up hills?
@@youngbuck22481 ,. The confusion here rests between 50cc and 150cc GY6 versions. 50cc scooters used weights around 5 grams and 150 around 15, that's just ballpark numbers I guess....
mate do a video on the boss getting stuck onto the shaft like my sym gts 250 and i am just kiling the thread on shaft the stupid boss is stuck on shaft and the other side of the rollers is stuck on thee other side of the bos its a nightmare please help me
What happens if you don't tighten the belt enough at the end? Could that cause the belt to slip and very loud noises from the variator. Because that's what's happening to me.
@@electronicsNmore Any idea what could cause the loud squealing noise. I was playing with the roller weights. Went with heavier first. Everything was ok, but scoot was slower. Went with a bit lighter expecting good results and the squealing started. Doesn't make any sense?
Ik I’m 2 years late but I didn’t tighten mine enough it came loose I lost power and the end of my cranks shaft it slightly damaged but not enough to need to be changed thank god
electronicsNmore Hello, thank you very much. Now I feel tha my scooter have all the rpoblems you describe in your videos xD. Carb problems, and CVT problems, it seems that theengine is in good shape cause there is almost no smoke an turns on in one touch. BTW. I have that metal-to-metal noise you describe, the loose belt and all-the-time closed clutch. when the bike is up in the stand the wheel always spins. even at idle. well... I bough a second hand hybrid Yamaha majesty YP250 1998 with a 2007 GY6 150CC Engine (external case is almost identical to yours). its too much to ask for that oldie. Thank you very much for the tips and the videos. If you have any other sugestion, please, leave it. My bike will thank you xD
electronicsNmore Any way. Whats the top speed of your bike?. mine is 50mph (if I want to reach 51 I need to push it by foot xD), as soon as it smels any hill it goes down to 30mph.. Maybe a cluch or carb or both problem. I will open it up the next week. Thank you in advance
***** Hello. I lived on an island which had many hills. The best setup for my bike was 15 gram rollers and 1500 rpm springs. I had good performance up hills. You can also have a carb problem, or low compression.
+electronicsNmore Hello, It´s me again. Thank you very much, really helpfull. When I turn by hand the engine variator fast I need to apply very much force to make it turn when the piston is at the compression stage, but!, when I turn the variator very slowly, the engine offers almos no resistance to turn. Can be that a sign of a compression leak? thank you in advance!
Ok I had my drive belt out in but after it drove slow in the beginning then would pick up speed and did this every time I stoped can someone help me with this ?

I would've loved to see how you used the filter wrench to get the variator off. I'm stuck right now and not sure how to get that part off.
Place the oil filter strap wrench around the edge of the variator to hold it.

what if you have a spoke like variator, would it work the same way?
No idea, never saw one like that.

Worn belt or the variator roller weights are too light.
@electronicsNmore Is this theory correct that after applying grease on round rollers in variator they don't able to roll properly and tends to slide which cause irregular flat sides. And these irregular flat sides causes vibrations on certain speed? Is it right?
I forgot to ask though too can you spray the rose with silicone to make them slide easier and last longer???
No, the oily residue ends up on the belt making it slip. I've used a thin film of powdered graphite for locks with no problems.

Hi Man. Do you just use torque wrench to remove the nut with the grip from the oil filter wrench?
A torque wrench is only used to tighten bolts.

+salisburyplain998
Maybe try 1 or 2 gram heavier rollers. The engine will rev less off the line. You may also need to inspect the clutch.
cheers thanks for the reply,Ill give it a go :)
+electronicsNmore Was this for a larger than 50cc GY6? The largest rollers I've seen for a 50 is 7 gms.
Don Diller
The procedure is the same for 50, 125, 150 cc scooters. Many sizes available.
I just put 9 gram ones on my sunny 50cc when my belt went 8k. up hills its slow 15mph faster on flat ground 40MPH up
working on a 150 cc scooter want to change motor to a 250cc f everything matches can it be done
Just buy an upgrade kit from 150cc to 180cc. The 250cc might be too big to fit.
That was good and explicit

Im looking for more climbing power, what gy6 mod do you recommend I shoyld try first?
Climbing hills requires using lighter rollers.
on my 150 what would be a good roller to use?
All depends on the terrain, or if you want good fuel economy. 14-15gm is ideal for hilly areas, and 18gm is good for flat areas where fuel economy and highest top end speed is desired.
What is a good roller weight for hilly roads?
The performance kit I ordered came with 5gran rollers should I order 15gram rollers instead?
The engine will rev like crazy before moving using weights that light.
my 150cc the gear is engaging at idle, almost dropped on side when I started it up and wasn't on it. Now when I stop at lights and such, it still wants to engage and I have to literally hold it back. I never worked on these but I'm going to remove the cover to see what's going on... any suggestions on what to look for??
Has the engine RPM increased at idle from the norm?
What performance racing rollers do you recommend for 250cc gy6
Sliders are good.
Would 15gm weight roller work on a rx50 wolf scooter. Same belt case as this one
It will work, but how it accelerates and top end speed/engine RPM will change if the weight is different than what's installed.
really usefull video...thank you

Is it right to apply greese/wax on rollers and in variator for smooth spinning of rollers in variator?
Or will it make more issues after some time like dust attraction, vibrations etc ?
No oil or grease
@@electronicsNmore why not? What issues will come?
@@Sidg2 Could get thrown all over the belt and make it slip.
@@electronicsNmore Is this theory also correct that after applying grease on round rollers they don't able to roll properly and tends to slide which cause irregular flat sides. And these irregular flat sides causes vibrations on certain speed? Is it right?
What are the 1500 r.p.m springs for? Help Please!
Sets when the clutch shoes push outward to engage the clutch to make the rear wheel rotate.
I hear a loud rattling but only when the engine is revving down. Like as I let off the throttle as I approach a stop sign. The sound is not present when accelerating or idling, only when slowing down or coasting. Could this be caused by worn rollers?
I initially thought I had a loose bolt somewhere that was jiggling but I can't find one anywhere.
You need to pinpoint the location.
hello i have a 150cc chinese scooter , it only goes 85km/h , getting lighter rollers will make it faster ?
No, heavier rollers tend to give a higher top speed, and better fuel economy.
I replace my variator and put on a new belt following these steps but now the scooter won't start. Variator and belt rotate but doesn't start
You definitely touched something else.
I've seen variator kits with 3 small springs in it what are they used for?
+Blaq IVen
Those springs go in the clutch.
I don't understand why they would be in that kit do those go bad when variator does?
GREAT INFO,THANK YOU

What is the torque settings for the variator and clutch nuts ?
All specs can be found online in GY6 manuals. Thanks for watching!
wont 18g rollers be terrible on take off on a 50cc gy6 139qmb?
mine has 5g rollers in in and it takes off ok but i ordered 4 g rollers for more take off.. i installed a new DLH racing variator and staggered my weights 5g 7g 5g 7g 5g 7g to get an over all average of 6g variation and it is slower on take off now so im going back to the 5g rollers until my 4g rollers come in a couple days.. im also going to install a 1500 rpm yellow racing clutch spring to help on launch.. im trying to find the best possible setup for 0 `to 30mph and pull a hill at a steady 20mph or better if possible.. i only weigh 170lbs .. what is your recomendation?
Lower weight rollers will cause the engine to rev a lot more before you start to move, and cause the rpm to be much higher at top speed. For best fuel economy, a heavier roller is best, but you lose speed on take off.
What about those people putting 18 g rollers in? I live in the mountains with lots of hills.. so would you put 4G rollers or 18g? I'm think of the 4G cause 0 to 35 is all that really matters as long as it can steady pull me up a hill doing at least 20 to 25..your thoughts on roller weights and driving up hills?
@@youngbuck22481 ,. The confusion here rests between 50cc and 150cc GY6 versions.
50cc scooters used weights around 5 grams and 150 around 15, that's just ballpark numbers I guess....
mate do a video on the boss getting stuck onto the shaft like my sym gts 250 and i am just kiling the thread on shaft the stupid boss is stuck on shaft and the other side of the rollers is stuck on thee other side of the bos its a nightmare please help me
That sure is a nightmare. I sold my scooter. :-(
What happens if you don't tighten the belt enough at the end? Could that cause the belt to slip and very loud noises from the variator. Because that's what's happening to me.
The belt tightens automatically if the variator/clutch is working properly, with the correct size belt installed.
@@electronicsNmore Any idea what could cause the loud squealing noise. I was playing with the roller weights. Went with heavier first. Everything was ok, but scoot was slower. Went with a bit lighter expecting good results and the squealing started. Doesn't make any sense?
Ik I’m 2 years late but I didn’t tighten mine enough it came loose I lost power and the end of my cranks shaft it slightly damaged but not enough to need to be changed thank god
I would’ve had liked to see how you unscrewed the bolts in the video that was not shown
What weight roller would I use in a 50cc Taotao scooter?
It's personal preference. First remove one that's installed and weigh it.
@@electronicsNmore thank you for answering.
Hi
my stock variator roller size is 20x15mm 18g, Can I use 18x14 16g ?
No, it will rattle too much. Use the same size it came with.
Quick question, what if you don't have the same variator plate? Instead of it being smooth it has teeth.
Never saw one with teeth.
Im trying to upgrade my cvt but the back plate that holds the rollers in is stuck on the shaft..how can I remove it?
If you have the entire assembly in your hand, carefully inspect it for retaining clips. If none seen, then you'll need to carefully pry it apart.
@@electronicsNmore finally got it! Thanks for the reply.
Hello, the belt need to be that tight? mine is a little bit loose. Thanks
+Jesus Palacios (JPdrums)
If your belt is loose, then you may have the wrong size belt installed, or the clutch pulley is faulty.
electronicsNmore Hello, thank you very much. Now I feel tha my scooter have all the rpoblems you describe in your videos xD. Carb problems, and CVT problems, it seems that theengine is in good shape cause there is almost no smoke an turns on in one touch.
BTW. I have that metal-to-metal noise you describe, the loose belt and all-the-time closed clutch. when the bike is up in the stand the wheel always spins. even at idle. well... I bough a second hand hybrid Yamaha majesty YP250 1998 with a 2007 GY6 150CC Engine (external case is almost identical to yours). its too much to ask for that oldie. Thank you very much for the tips and the videos. If you have any other sugestion, please, leave it. My bike will thank you xD
electronicsNmore Any way. Whats the top speed of your bike?. mine is 50mph (if I want to reach 51 I need to push it by foot xD), as soon as it smels any hill it goes down to 30mph.. Maybe a cluch or carb or both problem. I will open it up the next week. Thank you in advance

Hello. I lived on an island which had many hills. The best setup for my bike was 15 gram rollers and 1500 rpm springs. I had good performance up hills. You can also have a carb problem, or low compression.
+electronicsNmore Hello, It´s me again. Thank you very much, really helpfull. When I turn by hand the engine variator fast I need to apply very much force to make it turn when the piston is at the compression stage, but!, when I turn the variator very slowly, the engine offers almos no resistance to turn. Can be that a sign of a compression leak? thank you in advance!
Sir i put grease on the side of those rollers. Will that b okay??
Bad idea. Use a very thin dusting of graphite powder for locks.
Why is that
Ok I had my drive belt out in but after it drove slow in the beginning then would pick up speed and did this every time I stoped can someone help me with this ?
Thanks big help
