Description: NCY CVT Kit Gen 4 Yamaha Vino\Zuma 125 aka Super CVT transmission kit for Yamaha Vino 125 and Zuma 125 engines is one of the best dollar-for-dollar bolt-ons to improve your Vino 125 and Zuma 125 scooter transmission performance! Quicker acceleration, reach faster top speeds, and makes your Yamaha CVT the smoothest running transmission 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: Must re-use stock variator boss, Variator slides, variator top, washers, rear pulley plate shaft, slider pins, clutch nut, and nuts. 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. Example, lubricate slider grooves, slider pins, ball bearing seat, and inner funnel area with heat-resistant moly-graphite grease.

Installation: 1. Slack the belt by opening the CVT clutch giving 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 the 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's variator torque specs.
