Naraku Variator 88mm Sport Black (DIO, QMB)
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 the 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.

NOTE: Recommend using a new belt with this kit. Belt and the belt drive facing plates KEEP DRY. All, other areas apply moly-graphite grease when assembling.
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 variator torque specs.
