I'm running with .005 on all piston-cylinder clearances, absolotely no slap at all, .005 is still almolst twice the service limit according to honda's spec's. You can have the pistons knurled, which expands points of the skirt to close this gap down, I was going to have mine knurled but the machine shop didnt have a knurling tool small enough at the time so I said ---- it. she purrs like a kitten even upon a cold start up.

Yea .005 is 2.5 times the Honda service limit.
