NCY CVT KIT Gen 4 Plus (GY6)
Description: NCY CVT Kit Gen 4 Plus GY6 aka Super CVT transmission kit for GY6 125/150cc+ engines is one of the best dollar-for-dollar bolt-ons to improve your GY6 125/150cc+ or Polaris RZR 170! Quicker acceleration, reach faster top speeds, and makes your GY6 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: THIS KIT IS NOT FOR Honda PCX (See Part# 1200-1195). Must re-use stock variator boss, washers, rear pulley plate shaft, slider pins, slider seat funnel cover, clutch nut, and nuts. For some models like the Polaris RZR 170, you'll need to widen the NCY Variator Top plate center hole, with a dremel tool, to fit through its variator shaft. 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's variator torque specs.
