Description: Koso Variator 115mm Set for your GY6 125/150cc transmission! This variator dissipates heat better, has an increased CVT range, and has an optimized ramp design for improved acceleration!

NOTE: For some models like the Polaris RZR 170 you'll need to widen the Koso 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 Loctitetorque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
