Does anybody know what would be a good piston-to-cylinder wall clearance, running a Wiseco piston in a 89 KX 125? Is it .002"? I know running Wiseco in a car, it is. My cylinder is sleeved, and it's time for a top-end rebuild. I'm thinking about going from a 56mm bore to a 57mm. Any info would be great. Thanks Jamie...

I think on the box from wiseco it says .0015-.002 but on that bore I would probably ask for .002 - .0025 . Dont bore it until the boring guy has the piston there.

I always wait until I have the piston. That is what I was thinking on the clearances .002-.0025 but I wasn't sure. Thanks.
