NCY CVT KIT Gen 4 (Aprilia, JOG, Zuma 50)
Description: NCY CVT KIT Gen 4 aka Super CVT transmission kit for 40QMB 2-stroke engines is one of the best dollar-for-dollar bolt-ons to improve your Aprilia, JOG, and Zuma 50! Quicker acceleration, reach faster top speeds, and makes your 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: Will not work on first-gen, 2001 and older Zumas 50. Must re-use stock variator boss, washers, secondary sheave seat/funnel, clutch back-ramp plate, 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.
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 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 variator torque specs.
