Description
Moturo complete variator for 139QMB/QMA GY6 50cc
The Moturo complete variator for GY6 50cc four-stroke scooters with 139QMB or 139QMA engine — a wear kit that renews the entire drive head in one step. With 9 g weights in 16×13 mm, ready for installation.
The variator transmits the engine's torque to the drive belt and regulates the gear ratio via the centrifugal force of the weights. Included are the variator with fan wheel, ramp plate, fixed pulley, star washer, sliders, and 9.0 g variator weights in 16×13 mm. This allows you to renew the entire drive head of your scooter in one go.
The variator fits all GY6 50cc four-stroke engines of the 139QMB and 139QMA series. Tightening torques should follow the engine's workshop manual.
Replacement takes about half an hour with a variator puller, impact wrench, and torque wrench.
