ring end gap question
So I'm putting my 80 gs1100e back together with 75mm bores and pistons. What should the ring end gap be? By my math according to the wiseco chart the top ring should be just over .013" but they are more like .006". Did the last guy who did motor work on it just mess up or am I wrong?Tags: None

Ok thanks a lot! I was going off of wiseco's sheet that says multiply bore size by .0045" for street applications. So if I'm reading this right I can be anywhere from .004" - .012" on my end gap and be ok?

Do NOT use the Suzuki specs!!! The WISECO specs are CORRECT!!! You will butt the ring gaps & kill the cylinders once the rings expand with heat if the ring end gaps are too small! I REALLY wish anyone giving advice would check to make SURE they know what they are talking about before advising people. Ray.

I'm not bein a smart a** so don't take it that way but why would someone use a Wiseco chart and not Wiseco pistons? Either way thanks a lot for the help. Its awfully weird that my ring end gaps on the old rings are only about .006" but then again that could be the reason my 4th cylinder was toast .

Never go less than .004 for every inch of bore size so if you are at 75mm bore which is close to 3'' bore your ring gap should be at least .011 no less.
