Polini Variator Roller Weight Tuning Kit 15x12 (Aprilia, JOG, Zuma 50)
Description: Polini Variator Roller Weight Tuning Kit 15x12mm for Aprilia, JOG, and Zuma 50 2-stroke engines. The set consists of 4x6 cores and shells made of very wear-resistant plastic that is not affected by temperature changes. The shells are of course also available as spare parts. For better identification, the individual rollers have the weight printed on them, so mixing them up (as it can happen with other sets) becomes impossible. The set comes in a shatter-proof box.
NOTE: You must install these weights in an alternating pattern, otherwise a severe imbalance in the variator will occur. These rollers are designed for tuning purposes only and we recommend that they are not used for long-term use. Once you have determined the appropriate weight for your set up you should buy a complete roller set for permanent use.
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.
