Hey guys.

Was out for a run today on the bike, following a bullet 350, so going no more than 50.

I noticed that when i layed off the throttle there was a really loud buzzing noise coming from the engine. I thought it would be best to leave it till i got back and then have a look at it.

I got back, and went in the house. And when i came back out to leave again, i fired it up, but it was really loud. I mean really loud.

So i killed the ignition and got off. I knew it would be the exhaust as soon as i heard the shear noise.

Just as i thought, one of the bolts on the top end of the exhaust had fallen off, and the other was just about to, with the thing hanging out of the engine. I replaced the missing bolt and tightened the both of them after knocking the exhaust back into place with a rubber mallet.

Now when the bike is running, i can feel air being pushed from the bottom of the exhaust where its connected to the engine.

I will get a picture tomorrow when it's light, but does anyone have any idea if i can repair it, or if it would just be better off buying a new exhaust system.

The thing is pretty rusty, which lets the bike down overall as everything else is in great condition.

Its a 1999 model.

EDIT: It is still buzzing quite a bit, not as much but it is still there and really loud too.

Cheers

Just in case you need a replacement, as it sounds that a welded seal between the downpipe & collector has been broken and so probably requires someone to weld it or you could try some exhaust pipe sealant. splash some water on the area where you think it is to find where the air is seaping out while running the engine and turn off engine and patch it, if you can.

Righto, i have replaced the gasket. Seems to be ok just now. Couldnt hurt buying a new exhause though Thumbs Up

It was late last night and i wasn't thinking much so i didn't think that i could just replace the gasket. duh!

but yea, its all good now. I just need to take it easy from now on instead of redlining it on every gear trying to get some power out of the CG.

Thanks for the help anyways.
