This is not engine, this is ART! And yes, it's worth every cent. It's not only the price, it's also the attitude and post sales.
Stefano S., ITALY
Thanks again for this outstanding product, everything so far on it is just perfect!
Roger S., SWITZERLAND
Piece of art!! The shape of the intake and exhaust channels are perfect. Proud to be a dealer of your products in the Netherlands.
Arjan H., NETHERLANDS
Way better than anything out there. Very throttle responsive with more top end.

I’ve been working on Harley-Davidson engines about 40 years. I bought your set of cylinders and heads - some of the best work I’ve ever seen!!!
