Surely you'd get alot more money back on it by breaking it? You've got alot of highly desirable bling on that bike afterall. *Bagsy the radiator!*.

People will be more likely to readily pay good coin for individual rare parts to enhance/finish their own projects. Its just the hassle and time involved in shipping things off one by one i guess. And the heart break of seeing your project effectively coming to nothing after all this time and effort.

I agree with the general consensus that you could reasonably expect to get £3500 for it.

Personally i encourage you to keep it, if money is too tight now just store it and pick the game up again later. As awesome as it would be to have a proper RS250 (rather than just an NSR roadbike made to mimic one) i still think you'd always regret selling your current bike due to the emotional investment that i'm sure you will have made in it. I know i certainly feel attached to my bike after all these years of modifying, garage and track time - its certainly a constant source of enjoyment and that afterall, is what its all about.
