The engine upgrade kit will almost double your horsepower taking the engine from 49cc's to 70cc's. The effect will be additional 5-15 mph and more power. The kit includes everything needed including a new cylinder head, wider piston, rings, fuel and exhaust valves and valve springs and the necessary gaskets to do this upgrade using your existing head assembly. Installation of the kit does require some special tools and small motor experience, we strongly recommend someone who has small engine experience do the work.

This kit will fit the 4 stroke motor scooters with a chain drive engine such as the STA50, ST50 (Baby Harleys), Nitro50 and the Veneto (and clones)
