Description: Dr. Pulley 18x14 Variator Roller Weight Set for 125cc and 150cc 4-stroke GY6 engines. Dr. Pulley Roller Weights are the latest roller weights to hit the market and the most advanced weights available. These Variator rollers perform up to 20% better than standard round weights and last up to 18% longer with 22% less performance material loss. The weights have several unique features such as their composite material being nylon for faster performance.

Dr. Pulley Variator Roller Weights means better performance from your scooter no matter what stage you are in upgrading your scooter. Simply add 9-grams or 11-gram weights and a CVT Kit, and a new belt for a powerful upgrade. The larger weight size will add top end only when you are doing other upgrades to make up for the loss of bottom or take-off. The same is true for lighter weights, if you go too light you will need to make up for the loss on the top end. 125/150cc scooters we have found do best with 9-gram or 11-gram weights, use 9-gram for over 200lbs. 11-gram under 200lbs. Add the Dr. Pulley variator to complete your upgrade.

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 variator torque specs.
