Description: Dr. Pulley Variator Sliding Weight Set 19x17mm for Aprilia, Piaggio, Vespa 125/150cc, and many more. Expect better performance from your scooter, period. No matter what stage you are in upgrading your scooter, simply add Dr. Pulley Sliding Weights and a kevlar belt for a power upgrade. Dr. Pulley Sliding Weights are the most advanced weights available. These sliding weights perform better than standard round weights by allowing the variator to open farther for higher top speeds, and last longer with less performance material loss. The weights have several unique features such as their composite material containing nylon for better performance.

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.
