Currently spending weekends stripping down the bike to change the clutch, and took the exhaust off yesterday.
I noticed in Clymer manual it said "change gaskets" when reinstalling....
trouble was I didn't notice anything that looks like a gasket when I took it off.
Check the MAX BMW fische it says there are "gasket rings" that look like big crush washers.



Can they get stuck up on the engine as they certainly weren't on the exhaust?
At work at moment so won't get to look again till tonight...

Guess I need to buy 4 for the re-install?

Yes, they look look just like the picture, but they will be somewhat flattened out now. And yes, they pretty much always stick up in the head. You can pop them out with will a small screwdriver or pick.

That being said, unless one or more of them were leaking, which is highly unlikely, you don't need to change them.

Thx guys. No signs of leaks but for a couple of bucks I'll put some new ones on I guess to make sure.



sigh.. just rang our local stealer... as usual parts are about 30%-50% more than in US.... US$2.21 each on MAX site, Au$3.76 each here....
this is one item I missed ordering from the US, although I bought a set of 4 for Linton (Axle)... damn it. :mad:

Wonder what else I've missed... :(

Put a little grease on them before you install them in the head & they will stay there while you install the exhaust system.

Will do, thx Dave.
Your 30mm cutout got put to use the other day, but I've forgotten what that other short round tool/device with the 2 brownish rings I got off you was for, guess its a seal depth something or other... been too long getting around to this. :rolleyes:
Will have to do some more research... I know I bought it for a reason... :D


thats was quick - found it... "custom made reinforced 14 mm socket for the swing arm pivot pins" ;-)

This is what they look like after they are crushed and carboned up a bit.

Dave, do you know if silicone grease causes any issues with O2 sensors like RTV silicone does? Just curious if you used regular old grease for sticking them on.

It is the out gassing of acetic acid from the RTV that kills the sensors. Silicone grease does not do that.

is a little bit of 3% moly grease OK to use?

Any grease is fine. I always re-torque the nuts several times over a few hours because the rings take a little time to compress.

Thanks John. I knew it was some type of gas the RTV gave off. Didn't know if maybe heating up the regular silicone based grease might do the same. The only stupid question is the one I should have asked after it costs me money or pain.

Hey thanks Richard.... good to know for future anyway. Would have been half the price of the new gasket rings and I have a Supercheap account card too! It's one of the places where I get my oils and other basic stuff.
Thanks for looking, very appreciated! :wave
