Pistons and rings for 1984 Suxuki GS550ES

[Guest]

I know they might be unobtanion. Would like to find some .050 ring sets an .050 for my bike.
Thanks,

yah see rings often on ebay of various oversize never saw a full set
pistons are almost unseen I think these bikes were beaten to death on tracks and the parts sources for hop ups were eaten up

Thanks Cipher, yes it is hard to find parts for. I just got it restored and fired and then an oil leak at the base of the head so now am replacing the head gasket and base gaskets. I think I will look for new rings until I get a set and then just re-ring the pistons while I have it apart.

check the rings for wear against the manual specs I had a 70 000 km hard driven motor form this bike apart and the bires still had cross hatch and no visible wear

[Magnafique]

Will do when I get it apart. The bike has a shade over 27000 miles on it and was raced at one time but has not used any oil since I have had it. Bought it in 2002.

That being the case dont break it down the expense of gaskets is not worth it

Check the valves makes sure they are in spec then check the compression
Im sure your engine s fine

Why oversize? Unlikely to be needed

[Magnafique]

Well, I got a blown Head gasket causing an oil leak so I have to change that, and many have suggested that I change the base gasket and 0 rings while I have it apart. So thats what I am gonna do. Last time I checked the compression it was 135 across all four. Book calls for 142-199 psi

did you try retorquing the head as per the manual?
did the valves
a minor oil leak is hardly worth a teardown
also a bike can have gummed up rings from sitting
best to check valves and drive the **** outta it for many a mile then reassess
