Stage6 Roller Shells Replacement 19x15.5 (Aprilia, Piaggio, Vespa 50)

Stage6 Roller Shells Replacement 19x15.5 (Aprilia, Piaggio, Vespa 50)

Description: Stage6 Roller Shells Replacement 19x15.5mm for Aprilia, Piaggio 50, Vespa 2-stroke engines.

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: 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 Loctitetorque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
