burring sound

[JayDub]

I would take off the exhaust and shake it, tap it, shout and swear at it etc... it could be a stone fallen inside or even a weld broken on the baffle, its an easy job and you may get a clue - you may even refit it and the noise dissapears 

[ChillMan]

True, it could be some stone or something inside. It could possibly also be the screws where it's mounted - or even the screws at the opening of the exhaust.

This helped me understand how the shield is mounted:  (showing the exhaust without the shield - I didn't listen to the sound).

You people are my freaking heroes today. I bought my Tiger a few months ago and have been trying ever since to figure out if that noise was normal. The whole time, I was thinking the sound was coming from down in the drivetrain. After reading this, I walked out ad tapped my heat shield and voila! Broken rear-most rivet. Tied a piece of leather around it and took it for a spin and the annoyance has ceased. Thank you!!

That is brilliant, CO_885i! I have yet to get rid of mine and it really annoys me. :)
Was it a leather belt? What about heat?

that's what she said?

I put something in there. I cut an eraser/rubber into a wedge, and drove around... without burrrrrr!

Then the rubber melted a little into "newly chewed chewing gum"... if you know what I mean. And the burr was back.

Yup, it'd need to be something that can stand the heat.  A piece of silicon tubing would get you a result.

[ChillMan]

The eraser thing was just to test the theory. Plus I got a wonderful burrless half hour. :)

Tomorrow the bike goes to the workshop for brake/tyre, I'll ask him to redo the rivets as well.

Had that last summer.  Used high temp epoxy paste to stick it on.  Heat cures the paste,  sound hasn't come back.

Bike workshop fixed it today. Took it for a 100km trip afterwards today. NO MORE ANNOYING BURRING!

He wasn't too keen about this project because he said those rivets tend to spin when you drill, AND it is tricky to get the remaining parts out, once done. Still, he did it, partly because I did other work at the same time (front breaks/tyres) and it's the third visit with him this year. I might be back in spring for a 20,000 km service.

He didn't fit new rivets, instead screws and some part inside.
