Hidden pesky Exhaust Gasket

From my blog redstreak150cc.blogspot.com/2010/11/pesky-exhaust-gasket.html


When I removed and replaced the exhaust system while replacing my rear tire, I thought that the exhaust gasket was missing at the exhaust port. I was wrong. It was hiding.

I first bought a few 30.5mm exhaust gaskets ($2 each ) which are crush rings with a copper outer shell. Here's what is looks like (on the left, the ring to the right is the old exhaust gasket).

I removed the exhaust system again, and saw the old exhaust gasket in the port:

and then with a pair of pliers, I was able to pull the old gasket out:

Check out the recessed ring at the port ... this is where a 30.5mm gasket fits perfectly.

Then, I smeared some anti-seize grease on the new gasket, placed it in the recessed groove in the port (the grease kept it nicely in place), and reinstalled the exhaust system.

Ha, i had the same problem. I took the pipe off, and couldn't find the gasket at all. I actually thought
I had been riding around with out one. Or it fell apart or something. It actually ended up
Falling off by itself when I got mad and took a beer break.
Man I wish I knew that grease trick before I installed the new gasket. Holding it place,
Atleast 4 dozen times and failing each time got me real real mad lol.

LMAO get mad and get a beer. I wish I can do that on some of the repairs I do! I had this happen to me last week and after 2 trys of attempting to get the gasket one, I said damn and got out the black RTV.

I'm racking my head over my current repair, I don't know snot about what's going on with my scoot.
So instead of killing my liver, I switched to tea breaks lol.

Those copper ring gaskets cause the exhaust nuts to vibrate loose. Next time use a full faced gasket and you will never have a problem and the nuts stay tight...

nice bit of advice and information

another little trick when you have trouble with the new gasket falling out is to put a little super glue on it.. It will stay in place and come out when you want it to... The glue will hold it long enough to get it together but will let go later if you want to take it out for what ever reason.. works real good..

Trouble with the new gasket falling out

Good tip. It would burn out in the first few minutes of running the engine...

I have use high heat red silicone... holds the gasket well also
