I finally got some new end cans for my GPZ, and I've stuck them on so I can at least used the bike now.

However I can feel a small air leak, what should I use to seal this? (The leak is where they slip on).

Can you not just do the clamp up a bit more? Any pastes you use to seal it (GunGum, etc.) will make it a right bastid to remove in the future.

Go to your local motor factor and ask for a tube of exhaust assembly paste. Smear some on the inside of the larger pipe and make the joint up. Be careful not to get any on the outside of the pipes as it's a bastard to clean off once dry.

Or as a bodge try wrapping tin foil around the end of the pipe then re-clamp it.

Clear bathroom silicone is the bees-knees for fitting exhausts.

I shit you not. I've had it sealing the push-fit joint between the header and cylinder head on my Enfield for the last six months. You wouldn't think it could stand the heat but it does, stays flexible and just peels off when you want it to. If it'll survive on the header of an air-cooled bike (gets hot enough to blue the chrome), it'll survive anything.

Nobody was more surprised then me when this suggestion worked.

Yeah silicone is very resistant to temperatures.

Fire putty is what I have in my toolbox, never used it though Laughing

I can vouch for one better on silicone sealant, I used it to fix a sheared off bit that wasn't fixed by getting a new engine cover on my bandit. Crashed it and ripped out one of the bolt holes in the case itself, about 2cmX1cm wide, cleaned it all up with petrol, sealed it up and it lasted about 9 months until I sold it when it failed an MOT

The previous cans I had on (before they sheared off at the bracket) were sealed using silicone, I can attest to it being a decent fix also! As I don't have any and didn't want to spend a penny I went for the tin foil and tighter clamps ideas. Also patched up the collector box hole, sounds as smooth as a babys backside (if you could convert touch to sound!)

Cheers fellas! My neighbours must be very happy. My pillions too. Noise ever bothered me as I use in-ear headphones.

Well I managed to re-fit the exhaust over the weekend using the silicone sealant, and did 90+ miles with very pleasing results...

(Although I had previously used some spare leftover "bathroom sealant" that was in the garage... but it turned out not to be the silicone type Embarassed It just dried out, cracked and flaked off)

Glad to say the silicone option has remained in place, and gas tight, so will be keeping a tube in the garage as an emergency backup fom now on!! Thumbs Up Karma
