I am having a hard time with Suzuki stock piston rings. I have rebuilt this bike 5 times now and have yet to have the same ring end gap. I think stock is like .018-.026 and the rings I have are around .024-.029 and are new. I measure them at the top of cylinder and square them up also. So my question is can I use ane oversized ring and size it down with a file to .018" to keep it on the tight side, will it still be round and fit the cylinder properly. The bore is right on the tight side also, it is just the rings from Suzi I am having the problem with, thanks.
how old and worn is the cylinder
what is the piston clearance?,you might need next size piston kit
deglaze the cylinder
to check the ring end gap ,the ring needs to be below the top
of the cylinder ,(about one third down from top)
if the piston clearance is exceeded then it should be replaced
i've rebuilt bikes well beyond those specs and the ran fine
hope this helps :cool:
