Hello everyone. Looking for some thoughts/experience with doing a rebuild on a 1999 Sportsman 500. I just bought a 1996 Sportsman for a parts bike for the 1999 and want to take the engine out of the 1996 and clean it up and put into the 1999. Thoughts are to put maybe a Wiseco big bore jug and piston on it if available,haven’t looked yet and a big question I have is can you put a head and cam from an H.O. on this engine and if so, would there be an advantage in doing this. Just trying to beef a little bit a clean tight new engine.

Thanks
