Expander ring, upper or lower ring groove?

[billy]

Am I right thinking the expander ring shall be sitting on the lower groove? It doesn't seem to fit very well on the upper but I want to be sure..

Edit: It's for a 125.

yep.the t**t who owned my 125 previously had it fitted to top ring.mines now on bottom one

chuck it in the bin they can break up and cause problems.

Hmm, well bloody hell now you're making me nervous. I want piston slap reduced as much as possible (even though the bore is fresh and it has a new piston) but if it is too risky then f**k no..

EDIT: I have now done a search on the RD/RZ chat and it seems these rings goes pop from time to time, even when trying to slide the barrel over the piston rings. So, naah, I'll leave it out tbh, don't want to risk it.

im sure they there for a reason.not had one go yet myself

Well it's too late, I bent the f**k outta that ring to see what forces it could withstand, and it didn't break at all, it just bent. Now it's trash lol.. Oh well..

FYI it was a TKR piston. Is that what Yamaha put in the engines originally?

ive never fitted a expander ring on the 5 or 6 top ends ive done,many tuners will advise the bin is the best place for them

Thank's fellas, I now feel alot better about it all!

dont worry if you are ridding it properly you will be fitting a new piston soon anyway!! lol
