SSP-G Clutch Kit (139QMB, Buddy, RoughHouse)
Description: SSP-G Clutch Kit for 139QMB 49/50cc 4-stroke engines. It is one of the best dollar-for-dollar bolt-ons to improve your 139QMB, Buddy50, or RoughHouse scooter! Quicker acceleration, reach faster top speeds, and makes your 139QMB CVT the smoothest running transmission in town! From rapid downshifting to slow cruising, this thing is smooth. Ultralight balanced components, oversized wear pads, and state of the art polytetrafluoroethylene (PTFE) coatings ensure superior performance and long service life.
NOTE: If installing on a Genuine Buddy 50 or RoughHouse 50 must re-use the drive face and belt-size 738-18-30 (sold separately). 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. Must re-use stock variator assembly, variator fan, fan overlay, and washers. RoughHouse must re-use the drive face and belt-size 738-18-30 (sold separately). Most parts also will fit Honda DIO's CVT.
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.
