NCY CVT KIT Gen 4 Plus (GY6)
Description: NCY CVT Set is one of the best dollar-for-dollar bolt-ons to improve your GY6 scooter! Quicker acceleration, higher top speeds, and makes your CVT the smoothest operating trans in town! From rapid downshifting to slow cruising, this thing is smooth. Ultralight balanced components, oversized wear pads, and state of the art polytetrafluoroethylene (PTFE) coatings ensure superior performance and long service life.
NOTE: Recommend using a new belt with this kit. Belt and the belt drive facing plates KEEP DRY. All, other areas apply moly-graphite grease when assembling. Must re-use stock variator boss, washers, clutch back-ramp plate, clutch nut, and nuts.
Installation: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctite, torque nut to 30-35ft lbs. For reassurance please consult your manufacturer variator torque specs.
