first gen exhaust seals

[Chaplain]

I saw a comment somewhere about making your own exhaust seals on the first gen out of copper wire. Can somebody expound upon this please? It sounds ingenious.

I tried but gave up and ordered the muffler gaskets last week. Might have been my post you read recently

If your gaskets (where the rear downtubes meet the stubs off the rear head) are thin, you can take one wrap of #10 solid copper wire around the pipe next to the gasket and it'll help seal it up. All it's doing is taking the place of the gasket material thats not there. I don't think it'll work without a gasket in there, of course it will take more turns to replace the missing material. Worth a try, tho.

 

Good luck

Now I'm thinking some lead. You can shape it exactly. I don't think it will get hot enough to actually melt and run out or weld things together. :Venture:Of course, if the weather breaks it won't happen at all!

That's what I did with mine. Just cut a length of #10 copper wire the right length to make the gasket and then flattened it somewhat with a hammer and anvil, and put in place. I did mine in 2006 and so far they are still working great.

Exhaust temps at that joint can run up to 400 degrees!
