This video will show you how a CVT works and how to upgrade it with performance parts, starting with removing the CVT cover and explaining the functionality of the variator and clutch. I will also show you how to replace your belt. After showing the functionality, I will show you a step-by-step on making your modification with performance parts. I will explain the specific components of a CVT transmission, rollers, torque spring, and clutch spring. CVT stands for Continuous Variable Transmission. By changing the rollers, torque spring, and clutch spring, you will be able to adapt your CVT and make it work better for your needs.

What would you suggest me for 50cc scooter for better high speed? (Rollers, Torque spring, Clutch spring)

@zodiacorion8582 1 year ago

So if I wanna make mine faster and increase the speed would I put the 1000 rpm spring on and the 1000 rpm clutch springs on? And what roller weight would I use if I wanna faster?

Whats the best set up then for the "middle"?

@DavidSpraggs-z1v 1 year ago

What is the tool you use with the two pins to lock the variator in place so the nut can be removed? I’d like to buy one! Thanks

That's a great tutorial video. Thank you. Quick one for you though. My son and I are riding ATVs with GY6 1P63QML so with already a big bore of 63mm.(177cc / 11hp @ 7500rpm / 10.5N.m @ 6000rpm)

We do ride in the desert, mainly in the dunes, and I want to tune our CVTs accordingly (and sprockets eventually) but I was wondering, would it make sense to get the below combo :
- 10g/11g sliders
- 2000rpm torque spring to upshift later and downshift faster
- 1000rpm clutch shoe springs to still get early engagement from the clutch

Thanks in advance for your advices
Cheers

You mention a setup for more low end torque / dunes, but not sure if I missed what you recommended for that environment. Currently I have 12 gram weights and yellow 1500 rpm spring and I’m struggling on hills and soft dirt. What change should I make to gain the most torque ?

Great video I'd like to know what did you make your pulley compression mechanism out of? That's a great idea for the spring not to pop up?

I have a Trailmaster 200 xrx with reverse... Will I need to remove the tire or just the exhaust? I don't have any way of taking out the entire engine sadly. I think the belts blown because it starts and the buggy won't move. Thanks for the video and any info you can give me.

I have a kandi 200cc Chinese buggy. Will this work for my go kart??

@MrJamesTimmons 5 years ago

What would be the effect of installing a 1500 big spring but not installing the three yellow arm springs? Thanks and great video.

@dalle5840 4 years ago

How would you recommend me mod my ATVs CVT? The problem I have is that it is way direct in the throttle. I use it in the yard and it is almost impossible to reverse safely etc. So I would like to mod to make it as spongy as possible in the start.

Great video!! I just got my daughter a 2020 dongfang 200cc go kart. It seems to have trouble going up hill or over bumps and I can smell the clutch at times. Is there any maintenance or checking I can do to prevent this? Do you sell clutches for this model? Thank you

@jtotheace1 2 years ago

NOTICE - Be very careful taking apart the clutch! The spring is under a lot of tension. When the nut is removed the clutch disc can fly up and smack you in the head leaving you with a nasty cut on your face with bruise or worse.
