Metal on metal sound when O-rings from exhaust wear out.
Hi Everyone,
I have fixed this 4 times in the past year.. The o-rings SLIGHTLY wear and I get a metal Buzz sound from the front pipe. If I put my boot on the pipe it stops of course and if I change the O-rings it stops... So I know the problem and how to fix it, but it should not be happening every 4 -6th ride and Is there a known issue with this? I ask because Gofasters has a replacement exhaust spigot.. Seems ODD to have one on the site like that? |
McMasters has better viton o-rings that hold up much longer. I can't remember the size, but GMP knows what size they are. Or you can do a search here on them. I would look it up but I'm on my phone and it will take to long.

Another option is to clean everything really well and use high temp RTV to seal the connection.

Ps, I use the rtv sealent I have used red, and nine I'm trying the copper..

Check the alignment of the pipe, and also the lower pipe mount. I've found if the lower mount is flogged out it allows too much movement of the pipe which causes too much wear on the seal.
As above Viton o-rings and RTV Red. I was going through this every couple rides until I fixed the mounts up. Since then I can really scrag out the o-rings. |
I have had this problem and I found that the left side of the pipe was pushed backwards so the pipe did not fit straight on the cylinder.
|
nail a stump just right and it should make the fit nice and tight to stop that buzzing :D
|
One pipe buzzed & one didn't. the pipe that didn't was twisted & the front mount was twisted to get the bolt in. More tension, but pain in arse to fit.
I ended up fitting some extra springs on the manifold. buzzing stopped on straight pipe. (+ viton & sealant) |
