California Motorbikes Ported G4 Cylinder Engine Kit - 80cc 66cc Motorized Bicycle High Performance

Want to make your motorized bicycle go faster?

Check out this ported G4 cylinder from California Motorbikes.

It's designed for the common 66cc or 80cc 2-stroke bike engines.

The porting is done to improve airflow, which should give you a nice bump in power and performance over the stock cylinder.

It's a brand new, high-performance racing part.

If you're into building or upgrading your motorbike, this is a solid piece to get more speed and torque.

It's a direct replacement for the standard cylinder on those Chinese engine kits.
