Clutch Rear Pulley Assembly for SYM Jet / Red Devil / Jolie / Kymco Vibe / Super 8.
Clutches wear out over time, causing the pads to glaze and wear down. Torque drivers also wear out over time, as they do alot of work. Inside the torque driver are a series of pins and slots which allow it to open. Over time the spots wear grooves from the movements of the pins, causing the transition of the driver to be sudden instead of linear – which presents itself as a sudden drop in revs, like shifting from 1st gear to 4th gear in a manual car.
The easiest way to fix this issue is to change the unit. This assembly is super easy to bolt in! Once the transmission cover is removed, its as simple as removing one nut, and reinstalling.
