I am 35 .. I am driving scooters all my life, address ,gillera ,vespa,beverly , liberty... First time in my life i learnt how scooter transmission work ! Thanks bro .
everything is so clear when you get a real demonstration! I had looked at pictures and text explanations for a while but coudn't really imagine how it really worked... Now I understand why they say a CVT has essentially "infinite gears". Thanks!
you all prolly dont give a shit but does any of you know a method to get back into an instagram account..? I was stupid lost my login password. I would love any tips you can give me!
Very well explained! Even the smallest things in transmission can make a difference in performance. I've bought my second scooter - 2013 Aprilia SR50R (carb ) and I''m rebuilding it to 70cc ,i did rebuild my 1st scooter Yamaha Aerox to 70cc too ,but only changed the pipe, cylinder kit and air filter. It ran good for the small amount of tuning i did. But the SR50R i'm tuning a lot more -sport transmission ,Yasuni pipe , streetrace 70cc ,bigger carb ,intake etc. ,thanks to this video I learned a bit more about transmission tuning. I'm surprised that in USA the scooter tuning is also popular. I'm from Europe (eastern europe - Latvia) and here it's a very popular thing amongst teenagers and even adults. You can pass the moped exam if you're 14. ( I'm 16 btw.) We even have a scooter forum ,official scooter meetings twice a year (10 or 11 years since the 1st one) with cast-iron and aluminium class drag races , and a lot of scooter riders upgrade their rides a lot to win those drags..even porting cylinders and engine blocks. In the past I thought that in USA people only put 150cc big bore kits on their 4 stroke chinese scooters and that's all with tuning :D but I'm surprised that there are 2 stroke powerful builds with all the known brands - Malossi ,Polini , Stage 6 etc. A subscribe and like from me.
Finally, someone who can fully explain the functions of a CVT! I have a V-Moto Milan II 50cc and from the sounds of this video, installing all those components is possible, am I right? I'm in Australia and I've hardly seen any modified scooters in Adelaide...
I also have a vmoto Milan, 70cc eBay bore and piston, eBay expansion pipe, #80 main jet, I was having trouble with it bogging on take off, after pulling it all to bits like a million times, I eventually found the variator had a destroyed roller that was jamming it in top gear, I removed the dead roller and now no more bogging, I have ordered a eBay variator kit
Super cool video, I didn't know I could run it with the transmission cover off , I have a stock Wolf 50cc scooter very low miles and it started making a squeak noise during initial throttle, it sounds like my belt is slipping a little bit until I get going , after watching this video I'm confident I can fix it . thanks
This video is verry informative and it seems ro be hard finding that on youtube for scooters i have Peugeot speedfight 2 100cc but im lost knowing what parts to get for tge transmission 😂
Wow! I am going back to the Philippines and planning to buy a NMAX Yamaha scooter.I always wanted to know how it work and thanks for your vlog now I know...
Wow thats nice man actually i understand everything the way you explained and i also assembled those scooters in the philippines like honda dio mostly two stroke that was way back before and have a knowledge in putting those things for racing but financial is a big concern on our side that time so....but hope someday....hehehe thanks guys
we have to entertain. videos of only tech stuff would only have people watching 1 video every few months to years so keeping entertained while adding info. But thanks we have plenty of these!
Thanks and very nice of you to explain and even show how CVT works. I am new for this type of transmission and I have a Romet GT125Mx and I have a problem when it comes to stop and start to move in a ramp especially when having a pillion. the scooter is very sluggish to get going. what can I change and which things should I rerplace to get it better. Thanks once again.
I'm new to all this. My new 150cc scooter seems to engage a bit slower than I would like it to (manufacturer says it engages at 1700 rpm). There seems to be a bit of a slack in the throttle. How can I make it so the clutch engages quicker? By adjusting the throttle cable? Or by getting 1000 rpm clutch springs? If I change the clutch springs to 1000 rpm, do I need to also change the contra spring to 1000 rpm? How about the variator rollers weights? Do I need to change them to lighter weights as well?
may i ask how are the rules for you in the u.s. because i love to work on my scooter its fun and "relaxing some times" but if my scooter makes it to 80 kmh/ 50 mph they will take away my license and if you really unlucky the also conficated your scooter here in the netherlands. and what i always show the cops is he orignal manual from my piaggio typhoon. it says at 50mph atleast keep about 10m/33ft from the car in front of you. and they just say that its not true.
Us and Canada if you have a motorcycle lisence (even a beginner's) there are no limitations on which motorcycle or how fast it is. There is limitations on when and where you can ride and writhed or not you can have a passenger. Until you're fully lisenced.
I talked to Paul today at your shop, cant freakin wait to get my 08' zuma flyin down the road! Im thinkin about ditchin cars and start fixin up scooters
Does a stock Yamaha zuma muffler flow pretty good ? The reason I ask is I like the sound of the Zuma's stock muffler. I was thinking of installing a zuma muffler onto my Wolf booter
iam a heavy dude 135-140 kilo and i got a stock 50 cc scooter whit me on it its slow starting up but ok in top speed, how or what do i chance to make it faster in the start up ???
I don't own a scooter yet, but I plan to. I'm an old motorcycle rider who has to ride a trike due to my wife's many health iseeus. But I am now looking at scooters for the amooth ride. I think the engineering that went into a scooter's cvt is amazing. It is so simple and yet works so well. Your video does a great job explianing how they work. I will probably change the clutch springs on whatever scooter I buy. I will install weaker springs becsuse I want the clutch to engage sooner than stock. Then I will look into the rollers to make sure the front pulley is giving me the max it can give. I don't know if I will change the spring on the rear pulley because it seems to me if I have the right weight rollers in the front pulley it shoud over come the spring in the rear and give me the maximun performance. Well, good enough for me anyway. Thanks for such a good video on a scooter CVT and thank you for removeing the cover and showing exactly how they work. I already knew how they work, but it was nice to watch one while it was in action.
Great video..changed output shaft and seal on malaguti f15 rr 69cc. Used to do 50mph. Changed belt and rollers at same time. Now moped only goes to 30 but nice and 20 up a hill. Any ideas? Old flat rollers were 4.8g. tried 6g, 4.7g and now 4g.
There is no perfect weight every b ike every modification is going to be a factor. we just uploaded a video and paul talks about how to factor and adjust for that.
U r video is very useful to me, my back wheel was roasting but now not rotating ,I don't know what kind of problem until unless I open the cover ,the way u opened, & see what is wrong with transmission .many Tks for video
He made this vid to flex off the burnt titanium drive face 🤣🤣. I’m joking but nice vid I’m gonna start working on mopeds my self starting with my Aerox
Hey i have a 98 prebug im wondering what causes the belt to shift before the clutch engages. My belt starts going down on the rear pulley before the wheel starts spinning
5 років тому+3
I like CVTs in scooters, ATVs and snowmobiles but in cars I hate them. Mine blew out right after ended warranty what bullshit. Not cheap and easy but the opposite.
i used to say that keep watching videos u will be awesome like me it aint shit. electrical can be a royal fukin pain in the ass. just keep watching videos when a paticular area on ur scooter fuks up.
Hi Should the crankshaft lock? Their is some play moving it by hand or should it move freely? Just ordered new belt as old one was loose. Thanks Great Vid
Was that originally a stock horizontal minerelli engine? I have a Yamaha BWs cw that I want to put a horizontal minerelli l/c engine into with all high performance internals & don’t know weather to just buy rc one 70 cases instead??
Hi man. Another question, got 5g sliders on my stage6 vario and belt on the rear pulley just sits nicely near the top. However, at WOT on a sharpie trick i doesn't seem to ride high on top of the vario and left about 10-15mm mark. SHould i go for heavier sliders? Like 6g? Got 1500 torque and 1000 clutch springs on 70cc stage6 cylinder and sports exhaust.
I have a question, my cvt belt was worn out from 17,5mm to 16mm. but I ordered and installed 18,5 a thicker belt, I added some shimings in variator so the belt would stay as low as possible and it was as high as high in the rare (clutch plates). but it's still the same belt doesn't go all the way up on the variator, I squeezed the belt in the clutch as much as I could And I THINK THAT MY CLUTCH DOESN'T LET THE BELT GO ALL THE WAY UP 😫😫
Hi..nice vid. Wanna ask you if mine use 135cc What is better to modify the roller and torque spring.. should I use heavy weight and 1000 torque spring.. Daily use in highway..tq
I've got an uncle that lost his license for 10 years, but does work for me. Sometimes he rides his scooter in to work, because that is the only thing he can legally drive, but other times he has to get a ride. This slows him down quite a bit, as scooters aren't as fast as vehicles and he is a carpenter, but doesn't have room for his tools. I'm fascinated by these modifications, and wonder how fast and powerful you could make a 50cc scooter before it would be super obvious to law enforcement and get people driving with a suspended license busted. Also driving them in the winter is very very cold. I'll bet the 3 wheel trike scooters could have some sort of "cab" attached to help with that.
@@Scooterswapshop I live in Indiana. Per the law here, scooters are considered class B motor driven cycles and "Designed to have 3 wheels or fewer on the ground." I did go back over the law requirements though and they can only go 35 mph max. So I suppose if you did too much modification to them, they would break the law in another way. And it is just for people with a suspended license in Indiana. Scooters are legal to drive with only an ID card. You don't need a drivers license.
Hello!! Very great video.. Very clear explanation. Anyway just want to know why do you use Polini? Im still looking which one to get. Polini or Malossi? Any tips? Im riding Yamaha Aerox 155cc
Dahl this video and my other video on clutch adjustment should explain it. Yo really need to do the rollers clutch springs and contra all at the same time if your going to a big bore kit
@@Scooterswapshop right. but what i was thinking was, do i need to do the marker trick till the belt is riding all the way up, then goto then clutch afterwards? or is the belt riding all the way up not the most optimal?
Thanks for this. Do you have any idea, why is it that: on my scooter when i start mmoving with the bike at the beginning its shaking the whole bike for a few seconds and then its smooth again at a higher speed. So its shaking at the beginning of the speed up process, is the clutch spring not ok, or the whole clutch worn and not cathing the clutch house properly? Do i need to replace all parts or just spring or other parts?
I've got 6.5 and 8.5 gram rollers in my 50 cc zummer gy6 taotao now it's going 45mph on straight but sometimes it bogs down why,?? And I have ten gram rollers coming Monday so I was gonna take the 6.5 gram rollers out and put the ten gram rollers in should I or no
Good video, you made how the CVT works simple to understand.. The only complaint would be how many times you said "So." It got a little annoying after awhile.
I have a 2003 yamaha bws, did a brake stand and it started to wheel hop. I developed a vibration and eventually lost drive. IS it usually a belt that snaps or the cvt went to shit. I still have to take it apart to have a look.
So if my bike is only hitting about 8400 rpm’s and holding when I pin the throttle, what can I do to make it hit a higher rpm and have more speed? I have 1500 rpm springs, and I’m running 5.5 gram rollers or 5 gram one of the two, the bike is a 139qmb with a 50mm bbk on it , just a free barn find I built to wheelie but it’s really got me into scooters and I really wanna understand how to easily tune; bike will only do 41 mph @ 8400 rpms
If you started with a standard transmission, how would you go about adjusting from the word go? IE how much wieght to drop in the rollers, how heavy to go on the clutch springs and so on
So I went to the mechanic today with squeeky noise coming out of the cvt box. He openned it and tried to unscrew the variator nut and the kick starter ratched shattered into small pieces. What could have caused that? Perhaps the kickstart spindle was making contact witb it while I was driving? He did not say much since he was the who serviced it last time Thanks

How many RPM do you have on your clutch spring and center spring?
so this one is a full race build, stage6 medium and stage6 race clutch springs. it engages around 9500
I'm new to all this. My new 150cc scooter seems to engage a bit slower than I would like it to (manufacturer says it engages at 1700 rpm). There seems to be a bit of a slack in the throttle.

Can you make a video, explaining in what order to tune your cvt? do i start with rollers and dial in my vario first or do i start with the clutch?
Dahl this video and my other video on clutch adjustment should explain it. Yo really need to do the rollers clutch springs and contra all at the same time if your going to a big bore kit
@@Scooterswapshop right. but what i was thinking was, do i need to do the marker trick till the belt is riding all the way up, then goto then clutch afterwards? or is the belt riding all the way up not the most optimal?
This is such a genius idea. Is basically all centrifugal force that is so clever.
been around fo many many many years haha
@@Scooterswapshop never said it was a new idea. Haha
How do you know where your new rpm would be after upgrades?
setup on this bike?? Which spring and rollers??
Any suggestions on how to fix the deteriorating speed going uphill? What are those clutch parts that need replacement? My scoot is a Suzuki Nex. TIA.
shed weight from you or bike
Doesn’t the belt create friction against the side walls leading to some power loss
Somewhat yea. But it also allows the motor to be in the powerband at all times. A 35hp cvt bike will be faster than a 35hp geared bike most the time
Scooterswapshop i love the feel of the cvt transmission..doesn’t feel lacking in power to me
Does shimming the variator a little like .5-1mm shim affect top speed?
It can yes
Nice workshop, I'd like to have one like that:) How long does the belt last?
Thanks for this. Do you have any idea, why is it that: on my scooter when i start mmoving with the bike at the beginning its shaking the whole bike for a few seconds and then its smooth again at a higher speed. So its shaking at the beginning of the speed up process, is the clutch spring not ok, or the whole clutch worn and not cathing the clutch house properly? Do i need to replace all parts or just spring or other parts?
I've got 6.5 and 8.5 gram rollers in my 50 cc zummer gy6 taotao now it's going 45mph on straight but sometimes it bogs down why,?? And I have ten gram rollers coming Monday so I was gonna take the 6.5 gram rollers out and put the ten gram rollers in should I or no
Good video, you made how the CVT works simple to understand.. The only complaint would be how many times you said "So." It got a little annoying after awhile.
We are So So Sorry. No one is perfect, I would advise you to try making a video like this and see what you repeat its. interesting test
I have a 2003 yamaha bws, did a brake stand and it started to wheel hop. I developed a vibration and eventually lost drive. IS it usually a belt that snaps or the cvt went to shit. I still have to take it apart to have a look.
Are CVTs on scooters reliable or do they break often compared to manual transmissions on motorcycles?
Are there high performance belts?
Tons!
this was a very nice demonstration! must have been tough taking the video with one hand on the camera though!
Yes, thanks
So if my bike is only hitting about 8400 rpm’s and holding when I pin the throttle, what can I do to make it hit a higher rpm and have more speed? I have 1500 rpm springs, and I’m running 5.5 gram rollers or 5 gram one of the two, the bike is a 139qmb with a 50mm bbk on it , just a free barn find I built to wheelie but it’s really got me into scooters and I really wanna understand how to easily tune; bike will only do 41 mph @ 8400 rpms
How can I control the throttle if I'm down there looking at the belt ?
Any idea how to solve engine lugging? Im satisfied the acceleration and top speed on my scooter but the engine lug is terrible
If you started with a standard transmission, how would you go about adjusting from the word go? IE how much wieght to drop in the rollers, how heavy to go on the clutch springs and so on
step by step
I need some help with buying the right clutch assembly. I have an 80cc bbk , 139qmb engine
we have a custom build sheet you can do or call the shop
So I went to the mechanic today with squeeky noise coming out of the cvt box. He openned it and tried to unscrew the variator nut and the kick starter ratched shattered into small pieces. What could have caused that? Perhaps the kickstart spindle was making contact witb it while I was driving? He did not say much since he was the who serviced it last time Thanks
Sounds like
You need to take it somewhere else for repair. I have no idea what the issue is without seeing the bike in person
Good stuff. Why did you put the cover on and start it? Is there any reason for it ?
Because it’s kick start only
