Main reason for this is to improve my hole-shot. Had the motor rebuilt a couple of years ago, and instead of re-boring the sleeves, they put new standard size pistons, sleeves and rings. I lost some power and top-end in that deal. Went from 30 mph to 26 mph, and the hole-shot is good, but not as good as it was. Always looking to get a little more out of what I have.
