Hot Rod`s 660 Clutch Kit – The best overall clutch kit available on the market. This sheave is milled for even more bottom & top end, it`s the perfect combination of both performance & quality. Great for trail, mud and sand riding as well as rock crawling, plowing and hauling. This kit changes the gear ratio on the bottom & the top of your bike. A huge gain on low end power and torque, a stronger midrange & more on top end too. The extra top end is nice when you want to run low range so it doesn`t max out so quickly from mud hole to mud hole, trail riding, or working in the yard or farm. Helps restore power loss due to adding bigger/heavier tires & helps to get them turning in the mud. Better back shifting & throttle response. The lower gearing on bottom end will extend the life of your wet clutch & the higher gearing on top will extend the life of your motor. Reduces clutch heat & engine noise. Includes a new milled Yamaha sheave, Dr. Pulley OD weights, OEM camplate, OEM camplate sliders & anti-friction washer set.
Your specific bike set-up may also require an upgraded secondary spring in addition.
