Gs850 std size piston rings 69mm

[Guest]

I have been searching for new std size piston rings for my Gs850 head that I'm rebuilding. I am having difficulties finding these. My question is, I was thinking where there is manny different models out there that used 69mm pistons. Has anyone on here used rings from a different model and year?

Still available from Suzuki as PN 12140-45121.

Available anywhere OEM Suzuki parts are sold, including a multitude of online sources. Check the archives here for the opinion of the various US part sources. There are also aftermarket rings available for the 850. One of the few models with such parts availability.

Although this is 2 years old now.... I have used many rings from the ring companies to save mega bucks when purchasing piston rings. There are three measurements you should be aware of. Obviously the first is the bore diameter... the second is the ring thickness, (usually 1, 1.2, 1.6 mm in thickness) And finally the depth. You should get rings that match as closely as possible. You might need to take your pistons into a friendly machine shop and have the ring lands depth machined deeper or in some cases make the ring groove wider to accept a 1mm ring (Honda Shadow 750 OEM is a .8mm thickness.) I have machined those pistons to accept a 1mm ring. So instead of paying 80 dollars for a set of OEM Honda rings, I pay 22 dollars for 4 rings. Enough to do two Shadow 750 bikes. Or 11 dollars each compared to 80 dollars. And you often have a better choice of ring materiel.
