Title: Strange sounds/vibrations from variator
Post by: AgilityCitySport on June 01, 2016, 09:54:58 AM

I did some simple modifications on my Kymco Agility City 50cc, And after i change drivebelt theres a humming/vibrating sound from variator both front and rear. it starts after 45kmh and is strongest/most distubing downhills 50-70kmh.

i recently change new drivebelt and this problem started then.

The scooter is as fast at before but not comfortable higher speeds and downhill.

I also notiched a wear om the outer core of the new belt?

Using a genuine KYMCO belt, with numbers that matched the old belt?
