KB - 96mm pistons and stock overbored steel barrels. I'm getting ready to ring the pistons and check/set the gap. I believe the gap should be about .006", but can't remember and can't perform a search for some reason (some virus has dissed me).
I placed a ring in the top of the barrel and the gap was around .021". That's a bit over .006". Am I measuring it the right way? I measured my pistons and yes they are 96mm. Of course I 'll second guess myself and check again. Thanks dudes. Wow, post #100! I'm getting up there! |

Got some more measurments, but I think I may take it to someone with some more sophisticated tools to double check.
Cylinder bore top and bottom - 3.78" = 96.012mm Ring gap 1" down from top - .025" Ring gap 1" up from bottom - .018" Pistons measure (from top) 3.754" Skirt measures (from the bottom) 3.778" ??? Is this correct? should the skirt be 3.754 if the top part of the piston is? Is this "out of round"? I measured .008" clearance between P&C from the top when piston is all the way up, but there is very little clearance between the skirt and the bottom of the cylinder. Can anyone shed some light on this? Also, the Hastings part # is 4203 Muchos grassyass |
