Description: Prima Variator Roller Weight Tuning Kit 16x13mm test roller weight set for Honda DIO/Elite, GET, and 139QMB 4-stroke engines.
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!
Includes 36 Roller Weights, from 3gm to 14gm. Lighter roller weights will increase RPM for any given road speed. Heavier weights will lower RPM for any given road speed. Must be put in a 120° pattern!
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 Loctite, torque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
