By far the best invention for harleys yet, three models depending on your engine size and a clutch that will hold any horsepower and lock up so well that you will not have any slippage, yet give you a clutch lever that a child could operate it.
Highly praised by everyone that has bought one.
Contact info for "HIPPO" is on this page also. He is a top notch engine biulder.
