The vibes are not absolutely horrendous, and I can perhaps just get used to it. I rode Andy's 21 the other day (cheers, mate
) and while it was certainly quicker than mine (for the time being 
) it was not noticebly less vibey, so I guess it's just an NSR 'thing' - The Aprilia RS is similar. For me tho' It does take the shine off what is otherwise a great bike. I'll try the mounting bolts thing for the time being (thanks Jeff) and generally go over it all again to make sure everything is set as it should be etc. - but maybe I just need to wear two pairs of socks, stop being such a pansie and get on with it. 
Cheers
