As far as getting the sleeve pinched more than once, talk to ray and see what he says. I'd say you could repinch the motor more than once, but I'm no profesional.
Gotspeed2000, As for you not being the professional. I do my best find time fallow these forums / chat at the tracks (get alot of emails and text messages too) listening to you racers comments as to how your resized engines perform. The ease of rebreakin and how/when engine makes power (as compared to it new) has everything to do with the new designed fit I put into these piston + sleeve sets. Its all about the feedback I get from you guys racing. Professionally I am a Tool+Die maker better with alloy reconstruction than as I a racer now. As for the resized tightness most often requested my repeat customer base, is "light-medium". Everyones piston + sleeve set is return shipped with a great fit and improved surface finish condition.
