NCY CVT KIT Gen 4 (Vino, Zuma 125)

Description: NCY CVT KIT Gen 4 aka Super CVT transmission kit for Yamaha Vino 125, Yamaha Zuma 125, and Yamaha BWS 125 scooters. This Super Transmission Kit is one of the best dollar-for-dollar bolt-ons to improve your bike! Quicker acceleration, higher top speeds, and make your CVT the smoothest operating trans around! From rapid downshifting to slow cruising, this thing is smooth. Ultralight balanced components, oversized wear pads, and state-of-the-art Teflon coatings ensure superior performance and long service life.

NOTE: Must re-use stock variator boss, washers, clutch back-ramp plate, clutch nut, and nuts. Recommend using a new belt with this kit. The belt and the belt drive-facing plates KEEP DRY. All other areas apply moly-graphite grease when assembling. For 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.
