Polini Roller Weight Tuning Kit 19x15.5 (Aprilia, Piaggio, Vespa 50)
Description: Polini Roller Weight Tuning Kit 19x15.5 for Aprilia, Piaggio 50, Vespa 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: These kits are for tuning only and are not intended for permanent use.
Installation: Make sure variator drive face is seated properly and not get its teeth chewed by the Bendix: 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.
