I just saw a nicely restored 750 on ebay with an opening bid of 6250, but I doubt that guy will get any bids
I paid 500 for mine, and even though it was in a few pieces, the engine had been gone through enough to where I was comfortable with the rest of the work it required. I've put it back together, done some work to it, spent a few hundred on some parts, but if I HAD to sell it today, I would only expect to get 500 for it. thats the thing with these old bikes, you don't work on them to make money, you work on em cause it makes you feel good. in the end you get to ride something that makes you feel even better
