Good point. I usually hate getting putting prices on things I like. If my bikes were all worth exactly what I paid for them ($350, $850, and 50 silk screened T-shirts to be exact) I'd be a happy man, since while it would mean my estate would be a few dollars less, it would also mean that such machines would still be in the price range of riders young enough to still get some thrills out of them, not collectors. But all the same, I haven't the slightest inlking of a clue what a KR is worth - I mean, whether $200, $2000, $20,000 or $200,00 - and it would help me make decisions (like $50 sporty brakes or $800 factory race) if I had at least had a ball park figure.
Better quit now! If you start thinking in terms of value then there will always be a compromise. Should I go for the factory race brakes, or are modified Sportster ok? You know, that kind of thing. I say build what you like and forget the value. Unless it's to be a trailer queen or museum bike in which case this is lost on you.
