This kit allows you to have more torque and a better top speed with a completely original Chappy, it is not necessarily necessary to modify anything else to install this kit. You can keep the cylinder head, the carburetor and the original exhaust.

Nothing better to start again with a new cylinder and piston and no longer have any problems with a chappy being overhauled or renovated.
