Sorry to say this but my 06 280 is fine after trading in my 05 280. If anything I think I ride it better. It did take a few weeks for the suspension to properly bed in though.
I have fitted a Keihin carb which I didnt have before, but to be honest I think the Keihin improved the bike even more. Maybe you do have a serious fault, but all Uk bikes are PDI'd at the dealer etc.
Good luck with sorting it.
