First, you have to drain the crankcase oil out and drill your engine block to convert it to 2 stroke. Then cut the exhaust off and run 4" front to back = Happiness.
To drill your block for two stroke, get a 1 Inch bit andrill a hole just below the spark plug. poke a piece of rubber hose into the holes and attach them all to the hose coming from your fuel pump via duct tape. Full in the 1" holes with JB weld around the hoses.
Drain the gas tank and fill it with a 1 part oil 25 parts gasoline mix.
Drive it. It will rock- trust me.
