Aluminum bushing thingie?

Running a FMF silencer and stock header -

Where do you get a replacement aluminum bushing that connects the header and silencer? I tried FMF and they werent any help.

I cant remember if the one thats on there now came stock or with the silencer. Its completely worn out and exhaust is escaping though.

Any ideas? Something at the hardware store works mabye?

I had no luck getting one for mine, either. So I made one from some thin steel sheet metal from Home Depot. I suppose aluminum would work, too, maybe better than steel because it's softer and may squish out a bit.

I cut a strip of sheet metal about 1-1/4" wide and just long enough to wrap once around the header without overlapping. Then I formed it around the header to make it cylindrical. I make sure that when I put them together, the seams in the homemade bushing and the muffler flange do not overlap. It fits just inside the header/muffler joint and forms a (nearly) perfect seal.

I bought mine for $7 at the local moto-shop.

Just checked partsfish and they're $7.60

Merfman,

Are you referring to the stock muffler gasket? The stock gasket won't fit on my FMF muffler- it is way too big. That's why I had to make one.

See... this is why thumper talk rules...

I let you guy hash out which is the best way and then thats what I do! :)

Thanks for the replies guys.

MOmilkman, my riding buddy just went through this with his YZ. FMF recommended hi-temp RTV. He wound up taking his FMF SA to a local muffler shop where they cut off the FMF flange and welded on then expanded a slightly larger piece so the Yamaha factory gasket would work. Now he can quickly switch between the two mufflers without the RTV mess and using the factory gasket/clamp has no exhaust leaks.

Yea, that's what I was talking about. Is the clearance between the header and muffler much smaller than the stock setup? If so, I didn't realize that...

Thats odd.

I needed a new gasket for my fmf megamax II scilencer. I called fmf and they were more than happy to help. I needed new disk's to replace some damaged ones and they had them too.

They were more than helpfull.
