Description: The ultimate variator for your 139QMB transmission! The teflon coated roller tracks prevent debris accumulation that causes roller weights to flat spot, leading to extended roller weight life and consistently smooth transitions.

NARAKU sports variator for 139QMB and Kymco 50cc 4-stroke engines. When calibrated, this variator provides good acceleration at higher speeds. The set comes with 6g Variator weights 16x13mm. These weights are suitable for scooters in original condition. If tuning components (e.g. exhaust system or counter pressure spring) are installed, we recommend that you re-calibrate the weights. We offer various 16x13 roller or slider weight sizes.

This is one of the most versatile and compatible sport variator on the market works on Yamaha JOG Minarelli engines, Chinese Yamaha Clones such as the 1PE40QMB 1E40QMB engines, Honda Ruckus, 139QMB 50cc 4 stroke engines, Vertical Honda DIO style 2 stroke engines found in SYM and Kymco Scooters, as well as Aprilia Scooters with Piaggio engines, and Franco-Morini 50cc engines found in the 1E41QMB Suzuki AD50 AG50, TGB R50X, TGB 101, TGB 303 and Peirspeed Scooters.

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 existing variator fan, kick start gear, washer, and hand-tight nut. 4. Finally, torque nut to 30-35ft lbs. For reassurance please consult your manufacturer variator torque specs.
