DIY sleeve gasket ideas

[sleemanj]

F650 with two exhaust sleeve gaskets in need of replacement. BMW want to charge me near on $100+GST for the pair, which I think is... ridiculous.

Anybody got an idea on what I could do to DIY them?

I've got a tube of FireGum in the shed but I think it would probably be too brittle, I've got some high temp RTV, maybe even some copper impregnated stuff, but I don't know if it would be high temp enough or just burn away (anybody fancy a guess at what sort of temperature I'd see there).

Muffler Bandage.

I tried some of that red bandage stuff from supersheep on another bike once, very similar application, and it didn't stand up too well from memory, mufflers are a lot cooler than even the tail end of header pipes I expect, more surface area.

I wonder if some fibreglass rope gasket type stuff for BBQ's and fireplaces and such like might work....

I used some fibreglass rope left over from resealing a door on a kent tile fire.
Its in the joint similar to #5 on your diagram but it was an bastard to fit in.
I flattened the rope and made three rings then staggered the joints like you would piston rings with some white exhaust bird shit coloured stuff.
After flattening the rope I still had to expand the split socket end a good bit.
I probably could have just used two rings the third is in the split section under the clamp.

They look structural to the joint (sorry never really looked at one) and if they are no amount of magic goo will sort it out and FFS $100 aint the end of the world for a german motorcycle part. If it IS too much and if its just a bit of tube then you local metal factor should be able to help. By a longer bit for spares.

If its just a leak, hi temp RTV is the way to go.

Went into a fire place today (as in a place that sells fires) and found this, it's "fire door tape" (as in doors for fires), 25mm wide self adhesive backed woven strip of, well doesn't say what it's made of but I guess some type of fibreglass.

It's used between the glass front of a fire and the the fire door so I reckon it must be able to withstand pretty decent temperature.

I reckon it's worth a go. Maybe will spread some firegum or high temp rtv over it to help fill in between the weave. Was $24 for 1.8 meters prepackaged and distributed by Shuk Engineering www.shuk.co.nz

Looks like a better job than the flattened rope
