/forums/images/graemlins/frown.gifYa, I pulled the heads off and it HAS to be bored. I was hoping to just hone the and replace the rings. The manual says a max of .005 of ware. I have about .015 in the cylinder and a hole in the #8 piston. The speedo says 46,000. I figured about 146,000. After pulling the heads, I think 246,000!! What is funny is that the inside of the motor is really clean. Very little carbon build up. /forums/images/graemlins/thumb.gif
