I just put my 08 race cam in and aparently I screwed up. I put the cam in and put everything back in time, or so I thought. I turned the motor over by hand to see if anything was going to hit and it turned freely. Well, got everything put back together and started the bike and its makeing a whole lot of noise. Sounds like pistons and valves hitting. I just thought it was weird that I could turn the motor over with no problems and on startup it makes noise... any ideas?
