For those of you unfamiliar with roller weights, they are an important tuning device and have a significant impact on your scooter's performance! They should be checked/changed every 1000 miles (per maintenance schedule) to keep your scooter running tops. Over time, roller weights will develop flat spots which will impair the performance of your scooter.
A good indication that your rollers are worn is increasingly high revs for a given speed and/or decreased top speed. Replacing worn rollers will restore and actually improve your low-end power and especially your top speed. Fuel efficiency will also improve dramatically!
NOTE: Before use, lubricate slider grooves, slider pins, ball bearing seat, and inner funnel area with heat-resistant moly-graphite grease.
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.
