I've removed the engine bars and bash plate but the vibes are still present.

Once the tank is near empty I'll remove and remount it to see if that is the problem.

This is seriously giving me the hump after almost 13000 miles and daily use the vibes were never an issue, it now feels like the main bearings are going which they aren't of course.

I can't think what other cause there could be, any pointers appreciated chaps?
