Identify this gasket

[apogeecustom]

I received an Athena top end gasket kit and I know where everything goes but this gasket, of which two were supplied. Please help me know where it is supposed to be installed, and if you can also read palms, I'm not interested in knowing my future at this point. Thanks!

They seal the oil feed passage on the cylinder base gasket. Go to one of the various on-line parts fishe and check for yourself.

Is it #5? Thanks.

no not #5 you need to pull up the engine case picture.

Nessim has it correctly

they reside in-between under the cylinders base to the top of engine case at the rear of the cylinders, around the cylinder studs in a tiny same shape recess. (like around #6)

that picture looks like a KZ to me.

does yours actually use that o-ring/seal?

After looking at the correct diagram for my bike, it would appear that they are not needed.

The fishe at Alpha-sport.com says those oblong O-rings are needed. Please check your engine to see if there is a recess in the case, around the studs to capture the O-ring. You will know what I'm talking about when you see the top of the case.

Nice close-up! However, that o-ring looks like a badly molded POS.

I'd order new ones from Suzuki -- no way I'd install an o-ring that looked that haggard.

I've only got the valve covers removed so far and plan to take the rest down this weekend. I will certainly look for the recess.

 

[apogeecustom]

I couldnt wait for the weekend so I took down the rest and I seen no place for those o-rings.

FYI, found in my manual that those o-rings are only for chain driven bikes and my GS has a shaft drive.

Show us a picture of the top of your cases, where the cylinder studs are

Still, it could be true

Proof is needed

Now,

I am a believer

I thought the GS engine architecture was basically the same for all models, I stand corrected
