New vibrations!

[proteinsdef]

Hi everyone.

So I am riding along in the most horrible weather this morning, rain, 50mph gusts and 4 degrees C. I am on the motorway when I feel a sudden vibration through my feet. Its not a harsh vibration, but its noticiable. It only occurs from 30mph to 45mph and dissapears after that. It doesn't matter if I am accelerating or slowing down. Its not the brakes and there are no warning lights for the engine which seems fine and was only serviced 1000 miles ago. I have done 6000 miles so far. There doesn't seem to be any loss in performance, but its hard to tell with a heavy wind against you!.
Has anyone experienced anything similar?.

Well went out and had a good look. Turns out the top bolt of the exhaust has come out and is likely bouncing down the motorway somewhere. The exhaust is vibrating like a good un when the engine revs, so hoping a new one will sort the issue.

Would this work??
