    1150 ring end gaps

    I am just preparing my 1199 kit. The cylinders have all been honed and I have a brand new set of weisco rings. My Suzuki manual says end gaps should be .7mm on the first and second rings. I thought I read somewhere that the gap on the second ring should be slightly larger than the top one. Anyone confirm that and how far down the cylinder do I push the rings for measurement. Thanks, Bob

    I'd follow the Wiseco instructions.

      The .7mm in the Suzuki manual is the service limit...meaning wore out. Do not gap to that spec.

          On a street motor the ring end gaps should be .003 X bore diameter for the top ring & .004 X the bore diameter for the second ring. Therefore, 2.992 bore diameter = .008976, or .009 THOUSANDTHS end gap for the top rings & .011968, or .012 THOUSANDTHS for the second rings. Hope this helps, Ray.
