A 87 bike in peices for 500.00 is actually a really fair price. If it has a ton of aftermarket goodies on it then it is a steal but if it is mostly stock stuff then that is just a decent price. Stock parts are not really selling that well and if you were to put it together and took any consideration of your time for doing that then even if you could sell it for 2,000 you really are not making that much of a profit on it. If it was simply bolt it together with no parts to buy at all then it would make you a good profit. I would say buy it clean itup really nice and give it to the wife.
