Exhaust Pipe Wiggle

[TeamRealtreeHD]

Did alot of maintenance to the banshee tonight... alot. Cut brackets off the frame, greased the axle bearings and front wheel bearings, and fixed the right head pipe that had a small wiggle to it.

 

I took the o-ring out, but didn't replace it. I sprayed some pure silicone in there and put the o-ring back in. It fixed it nicely... and should expand pretty well when it gets warm/hot.

 

New o-rings from let's say FMF, the ones that are universal for alot of pipes, do not fit the trinitys. I would have to order them directly from Trinity. So I used the silicone. I will replace them over the winter for sure.

 

What are other methods you guys are using? Anyone else use silicone? What were the results?

I told you I used the hi-temp silicone when I put the Fatty's on. But all I did was put it on the o-ring to get a better seal.

i use that high temp rtv black silicone stuff on my silencers where they butt up to the stingers, works great

[TeamRealtreeHD]

Oy yea, I forgot about that... I was thinking about that problem I think when you told me. When I get thinking on something like a tuning problem that you had, I kind of blank out and get in the zone. But now that you mention it, I do remember you telling me that.

 

Was it a liquid, like a watery silicone out of a spray can? Or was it a creamy out of a tube?

i dont use o rings on pipes any more, just some hitemp silicon on the place for the oring and another bead at the end of the flange on the motor, let them dry then put the pipe on

creamy black stuff in a little tube, 600 degree

I used the spray stuff but then I figured out I should have used the thick stuff in the tube. But the pipes and o-rings were brand new so I should be good.

Re-did them today with some high temp Permatex RTV. That stuff is the ticket

I found this HVAC stuff good up to 600*F it was aluminum in color, so what ever I couldn't clean up you don't see. Plus it worked great. Sealed like a champ. Still good after about 40hrs of ride time. But I don't have the Trinity's.

My exhaust fits awesome. I love it and plan on keeping them after some thought.

 

The only problem was they still have the original o-rings in them after about 7 years of use. But I took them out, heated them up, put them back in and did the silicone. She's tight like a virgin now

I have never used anything to seal them. Is that bad?

[TeamRealtreeHD]

If they don't wiggle or leak, then why would you have to?

 

I take them off often... lately at least. The more you take them off, the o-rings wear and tear, etc. The seal becomes worn. Your best seal with o-rings in the exhaust will be the first 1-2 times you install.

 

As long as you are not leaking, don't bother. Wiggling as well is not good. But this Permatex RTV stuff I just picked up is made to make gaskets and such. Good stuff. Protects way past 500 degrees. So it is good for the bike and reliable.

 

I am letting it completely seal overnight... although it sealed instantly when I put it on earlier. They say it is completely done in 24 hrs.

I have a set of the FMF gold series pipes and they do wiggle a bit, though they are firmly on the machine you have to grab hold and actually get them to move some (wiggle). I've been meaning to post a ? on here for awhile about pipe fit? Should the exhaust flange on the head (exhaust port) be showing any? Mine does show between 1/8 & 1/4 of an inch and i have been having a constant light-medium popping noise in the right side cylinder for some time now (although both sides do have a sealing gap between the pipe and head. My pipes also do rattle sometimes and vibrate (shake lightly).

Let me rephrase that the popping in the exhaust is at the rear right silencer not at the front of the bike.
