Have you thought of just a " One over ", or a " Two Over "... A friend has a 450 Foreman and his was smoking bad. It needed new rings and piston because it overheated so bad. He went with a " Two Over " which is a bigger piston, rings, and jug... This took him from a 450 to almost 525.. Just a thought. Apparently, from what I have heard,you can go only to " Three Over ".
This would be a great mod for a bike with a good amount of miles and want a better seal in the motor. Apparently, they sell these in a kit and could probably do this yourself with some tools. He had the shop do his and he see's a big difference in power. Just a thought...
