FMF Pipe Installation
(Click here to view the original thread with full colors/images)

I just installed an FMF Rev pipe on my 01 200. I noticed that the stock pipe had rubber rings/seals at the end of the pipe that fits into the head but the FMF has nothing.
Sure enough, the pipe leaks goo when started. Was I supposed to add a gasket or pipe seal or something before I installed?

I just used the rubber rings from my stock pipe. FMF's failure to include rings seemed kind of strange and the rubber rings seemed a bit thin (i.e., they didn't stick out from the grooves in the pipe very much so they seemed like they wouldn't make a really good seal). I haven't noticed any exhaust leaks, so I assume I'm OK.

Yeah, you can use the ones off your stocker if they aren't too flatened out. If not you should definately get some new ones from Kawi. They will stop the spooging...

You'll want to use the copper gasket that goes between end of the pipe and cylinder and both orings. Clean up the socket the pipe fits into and the end of the pipe well. Then apply a small amount of silicone around the orings and install the pipe. You should apply enough silcone its pushed out from around the pipe but not so much you force it into the pipe/cylinder. This will prevent the pipe from leaking for a long time and it will still be very easy to remove if need be.

Canadian Dave's Answer covered just about everything but I always like to add my 2 cents. The copper gasket serves two purposes; the first is to isolate the pipe from the cylinder. I've seen older bikes without the copper gasket where the steel pipe has actually worn into the aluminum head so far as to trash the cylinder. (take a steel screwdriver and rub it against a piece of aluminum, and then think about how much a 2 stroke engine vibrates). The second reason for the piece, to a lesser degree, is to adjust the powerband . Aftermarket companies are now offering thicker gaskets to change the hit. When you think about it, it does make the pipe a little longer. If you ask me, I think some bored engineers have a little too much time on their hands. The RTV sealant is a good idea with sacked out o-rings. The manuals all advise to change them every time you remove the pipe. By the way, I have found OEM better than ones from leading pipe manf.They fit better. Pipe companies don't usually include the o-rings for a simple reason: about $10.00!!!
