Not sure iceracer, how bout you? The one I'm running right now is at .043. By the way bud, I did state my reference for all to see, and also my disclaimer that I'm not a champion engine builder. I was just saying what I would do. Right or wrong I stand behind all my statements on here. I want this guys motor running right as much as anybody on here. I guarantee ya that. And I don't want any of his money, or any brownie points with my favorite builder by sending his cash there. I got that info on squish from gordan jennings book. He's forgot more about two strokes than most of us will ever know. I stated my freakin references and told the guy that that is what I would do. Now you can tell him whatever you want but you don't gotta go get sassy with me in the process.
