raptor 700 JE 12:5 piston
« on: April 09, 2009, 06:56:06 PM »
It has at most 12hours of ride time on it. standard bore. im going with a diamond piston and just pulled this out tonight. If running X-4 it wont work the best you can see where the valves were touching. did not hurt the piston at all, and i will offer money back if not satisfied. I was this close to destruction. make resonable offer

Do you have a milled head or something that would change the clearances?   I did not think there was any worry about a 12.5: piston hitting with the higher lift  cams.
