    • GruBee 5G is the only Belt Drive Transmission currently made for this engine that we know of.

    • 8M Belt operation is quieter than a loud noisy #35 chain drive.

    • Centrifugal Clutch has a needle bearing instead of a bushing.

      FYI:    Harbor Freight is your exclusive source for EPA certified Predator 79cc 4 cycle engines.   

    My WAG, ( wild ass guess ), is that our transmission may also fit LeFan’s 79cc vertical cylinder engine.  We have not had a chance to check it out yet.    We just got back from China when the airlines started flying again.    We were stuck in China for 9 months.
