I have not sanded or honed the sleave at all. I bought the motor used from my LHS and they did not know how much fuel has been thru the motor so im assuming there has been a couple of gallons thru it. But i have smothed out the top of the piston so the pitting is not as bad along with the head button.
And at first i was poping plugs pretty quick but im on the same plug for the last 2 or 3 tanks but. Im thinking the pre-detonation problem was poping my plugs because they were deformed and all.
So i guess everyone agree's that the wrong shimming is my tunning problem? and pitting problem?
