For some reason Sean this didnt come through on the last email so i willl send it again. I probably hit a wrong button or something Don well i have yet to hear it. and i am not know for building snug mtors either. Let me jump right on a limb and put it this way. NO ONE who has ever done it has heard piston slap. the only people who hear it are the ones who never have or wont try it. I m sure somewhere there is an extreme where it would be heard (+010 clearance or something) but i have run them all over the place clearance wise and have yet to have noisy one.
