Stage6 Compression Spring Medium (Aprilia, Piaggio, Vespa 50)
Description: Stage6 Compression Spring Medium for Aprilia, Piaggio 50, Vespa 2-stroke engines. These black-coated torque springs from Stage6 are available in different strengths. Due to tuning, the drive belt may start to slip, which will make a stronger torque spring necessary. You will usually notice that the engine revs up but you can't feel any acceleration. The strength of a torque spring is marked on the spring itself so you won't have any problems identifying it. Dimensions: 4.3 x 58.1 mm
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.
