High Performance 70cc Cylinder Kit

Four Stroke 139QMB 70cc 47mm Cylinder Kit with piston rings and gaskets.

Bolts right up no engine case bore needed.

No problem using stock head stock exhaust and cam, although these can be added for even better perofrmance.

Its always good to jet and add air filter when doing upgrades to cylinder. On most four stroke scooters this kit works fine with stock jet and air filter.
