hi, new member here. I was wondering if the 2009 mod smr 510 had the same valves as 2008 mod?And its the second time my husky has hit the intake valve with my piston ruining my head and valves/piston along with it, the first time it was with the privious owner.could it bee bad timing? i would think if it was timing it would happen a while ago.could it be over reving?mby bad luck?hope to get some answers thx.
damn sure the valve size is the exact same.. stem dia was changed in i believe 05 to a thicker stem. going to guess you are over reving it. did you put new keepers on the valves ?
