I was really impressed with this kit. One of the best packing jobs I've ever seen for a kit with so many parts. All parts seem to be very good quality and matched together as they should. Better than expected. I would buy again.

Very low quality piston bore was way too tight motor was smoking. Had to buy a wiseco piston setup to replace it they didn't even know what the ring gaps were on it. If you like to tear down and rebuild engines this is the product for you other than that I would not buy it again.
