Why several times bolt at my variator get unscrewed. What I made
wrong ? After I changed belt variator get unscrewed but after 3000
km. I change bolt and front pully half. Thing was ok for next 500 kn
and happened again. Third time shit happened after 50 km. ????

I own a QLINK 250 legacy and I am very pleased with the bike itself. I love the automatic bike but I wish the bike had more power. The best I can get is 62mph and that is full throttle with the wind at my back. If anyone has any suggestions on how to make the bike faster I would greatly appreciate the knowledge

brilliant article thanks this has really helped me to understand how the CVT transmission works. am in the process of playing around with variators and contra springs on my Jog RR so this has come in handy to help me understand things better.

I believe it should be Continuously Variable Transmission.

The only time I’ve heard Constant Variable Transmission is in error.

An excellent and well-explained article! I have enough confidence now to tackle a bit of essential work on my other half’s scooter… and hopefully get her back on the road and off my back!

HI, I have a (stock) Vmoto Monza that goes quite well at high rpms, but is really quite slow on take off. I have ridden a few others that ‘Jump’ off the start (which i would imagine would be better in traffic)... would this have anything to do with the clutch linings being worn out? (it has over 5000kms on the clock) Would replacing it gain any advantage or am i better to play with variator weights and contra springs?

I have a problem.

When I first accelerate my scooter from a dead stop, the clutch catches and bolts akin to a beginner trying to drive a clutched vehicle. This is most noticeable when it’s been sitting around for a day.

Do you know the problem and what the solution is?

Bravo, the easiest and quickest way is to buy or borrow someone’s impact wrench, and socket. It will spin off easy.

Bravo !
I have tried to release the bolt on driven pulley (as you explained above), but did not success yet.
Could you show, which tools you have used, & the procedure step by step?
Thx anyway
