KOSO Complete Clutch Kit with Adjustable Clutch and High Performance Clutch Bell
Solid Clutch and Winged Clutch Bell from KOSO make the perfect combo to get it done for your Yamaha Zuma 50 or 70cc Scooter. When doing CVT upgrades this is the way to go for take and top end increase when doing engine mods for better top speed. The KOSO clutch stays in the power band perfect with great rebound from quick slow down to getting back up the hill.
For the best performance you should add a Dr Pulley variator with slider weights along with an ETI Kevlar belt.
Great set up that gets the job done for two stroke scooters using the 40QMB engine which is all chinese models including CPI ADLY Moto QJ and Jonway.
Kit is also top notch for Yamaha ZUMA and Quads using Jog engines 70cc and 90cc
Adjustable for fine tuning.
