I have a 07 Sportsman 800 EFI that I just blew the engine last week when I was in West Virginia. Tore the engine apart and the connecting rod snapped, camshaft broke, cylinder head is cracked and one valve is toast. I am purchasing a new engine soon. Does anybody know if the 2008 engine will mount and hook up in the 2007 frame. Is it true that it has a little more HP. It is the same price so why not if I can get more HP. Thanks for any help. New to the forum but like it so far.
