Help with xs1100 exhaust gasket size

[bruce2]

Greetings all,

If anyone has an exhaust gasket to hand (the ring seal that goes in the head to seal the header pipe to the head) I would be grateful if you could measure it and give me the outside diameter.

I don't have a bike with me but want to try to find some suitable gaskets from a loose selection of various sizes that I have access to.

thanks in advance
Bruce

Hi xschop.

Thanks a lot for the reply.

37mm I.D.
45mm O.D.

Could I ask are you measuring a new gasket or a used one - I'm just asking as 8mm seems like a pretty thick wall and I'm wondering if it might have compressed down a bit to close up the ID a bit - but then its several years since I've had any pipes off so its very likely my memory is faulty. Regardless, its the OD thats most important........

thanks again

not 8

4mm (8/2).... the xs11 exhaust port has even more width from exhaust exit to outter gasket seal....plenty for smashing

Thanks mate, the clarification is much appreciated - yep 4mils sounds about right according to memory. In that case I'll look around and see what odds and sods I can see just a bit under that 45 od.

thanks again,
Bruce

I'm sure a 46 or 47 would even work... they are really loose in the ports when new. I wouldn't go smaller than that.

Just measured, I get 38 id & 46 od, unused XS11 crush rings, genuine yamaha part No 4BE- 14613- 00 K021218A

yeah 47 would be max

tinkering some on the Bandit headers, I may have to get a custom set.....
