Exhaust Gaskets

[lisk]

Hi Guys! I have had my XS1100 for several years and have replaced the stock pipes with a Jardine 4-1 header. As long as I have owned the bike there has been a bit of an exhaust smell while riding. Are there supposed to be gaskets where the header pipes meet up with the motor? I think that someone may have done work on the exhaust and never replaced the gaskets and it never occurred to me that they were missing! Thanks for any advice you can offer.

Yes, there is supposed to be gaskets for each header pipe. They are thin crush washers, ie when you tighten the exhaust to the head, they crush to make a seal.


Just curious, where 'bouts in Ontario are you?

Thanks Brian I appreciate the reply. I'm in Oshawa. I see you are in Windsor! Not too far apart are we! I do most of the maintenance on my bike and can't believe I over looked something so simple as missing exhaust gaskets! I've been chasing this exhaust leak for some time now! I get tired of smelling like exhaust after each ride! The reason I wondered about the gaskets is that I noticed that whenever I removed the lowers on my fairing the smell wasn't nearly as bad. I figured it had to be coming from that area. Anyway, I think I found it now.

Thanks again, Cameron

Hey Cameron,

They are aluminum, and can get squashed into the head so much that they can look like part of the head. It was hard for me to tell what was the head, and what was the gasket, but once I started prying on that extra ridge, they came out! They aren't a snug fit when you go to put the new ones back on, so it has been recommended to put a thin film of silicone on one side to keep them in the holes until the pipes are in holding them in place!

I'm surprised that you hadn't also noted that you have had some popping of your exhaust especially during decel?

Exhaust gaskets

Thanks for your response, I actually did notice the popping on deccel but it wasn't too bad. Thanks for the info and the sources for gaskets I realy appreciate all you guys taking the time to help on this website.

Can you use a thin film of muffler cement on the gaskets to do the same as the silicone?

Thanks again, Cameron

I just did a quick search for Muffler Cement, what I found stated that it was made up of a mix of IRON and silicates, and eventually hardens. I had just suggested Silicone RTV for it's temperature resistance. IF the pipes are well secured they shouldn't move during operation, so once compressed, the muffler cement shouldn't be a problem either!
