What is it worth cleaned up and parted out? I'm not familiar enough with the singles (yet!) to know if this could be the case, but the price some guys will pay for bevel twins just for the parts is surprising. (I'm looking for a single now, and no, I wouldn't have paid that much for that bike either)
My latest project is a '74 750 GT. I got it for $700, knowing full well I'd have more than what it was "worth" into it by the time I was done. The guy could have gotten more for it, but wanted it to go to someone who would fix it rather than part it out. From a financial view, it was a great parts bike and a horrible restoration project.
The way I see it, if I could have gotten him to pay me about $4500 to take it, I could have broken even on a rebuild/sale.

(Not including any value for my own labor of course!)

There are very few bikes that are worth restoring from a financial view. But this opens up the whole question of what a "restoration" really is, which is a whole 'nother topic. For most of the bikes I can afford, if it will be worth the money to "restore" then it doesn't need enough work to justify a restoration to begin with.
Reminds me of a comment I heard some years ago about estimating what a restored E-type Jag was worth. The guy said you should add up the restoration costs and divide by two. I don't think he meant it as a joke either...
