I have a 1997 Foreman 400 that had some piston slap and needed to be rebuilt because its been burning oil for a while. 675 hours and 3,xxx miles, so I’m not surprised at this point. Pulled it all apart last night and found that the cylinder isn’t damaged too much, but defiantly needs to be bored. Valves look good and are straight, and crank/rod doesn’t have any play. So here is my thought on the rebuild.

Can I just call it good, get the .040 over kit and have it bored to match that at a machine shop? Am I going to sacrifice reliability going that much over? I don’t care if it has more power, I would rather have it be just as reliable as it was. Thanks for your input! This is my first time rebuilding a top end.
