Exhaust leak? - SV650.org

jonny.boyd · 23-03-10, 09:39 AM

Just a quick question before I nip over to the garage.

I've noticed recently that air is escaping from one of the seals where the exhaust pipe connects to the can. From what i can see there is a rubber seal that is meant to be securing the air tight seal but this is obviously failing. Now my bike is still under warranty but not for long. If I go to them today and tell about the problem they'll probably just blag it off and say it's meant to do it. As far as i was aware the exhaust system should be sealed and airtight (apart from the end obviously and maybe a hole in the mid-section) but there shouldn't be air from the seal should there?

Any help / advise relating to this would be great!

Do you have a replacement exhaust? The standard exhaust is all welded, and is substantially one piece with no rubber seals, so I assume you have an alternative of some kind, in which case we need to know a bit more, the make of the can and perhaps a picture showing the exact location of the leak.

I'm not with the bike right now so I will do my best.

Please find attached picture of the can, and picture showing where air leak is:

sorry in answer to your question yes it is a replacement (not fitted by me, came with the bike). It has a Viper exhaust (not sure of which exact one).

There isn't a rubber seal in there, but there may well have been some silicon sealant or similar used when the exhaust was fitted. If you can get the seller to refit it all well and good, if they're not keen it's easily and simply done yourself.

Just under that metal plate you can see circled in the picture is what looks like a circular piece of rubber sealing the gap between the can the exhaust pipe. Is it bad to have the exhaust system not air tight before it comes out the end? I'm looking for a good reason I can give the garage for wanting it fixed.

I stand corrected, went to garage, he tightened up the clip helped but didnt stop the air leak but better than nothing. Case closed, thanks for your advise sid squid!

TBH a bit of a leak there might cause a bit of grumbling on the overrun but won't do any harm.

mine leaks all over, havent got round to resealing it yet but will this week some time, i use out door drain sealant, because its black and dosent dry that fast so you can mess around with it for about 30min after

But wouldn't it melt / smoke with the extreme heats the exhaust gives out?
