I would try to diagnose the source of the leak. Most likely a simple fix, hose clamp somewhere. Then the general condition and the "extras" determine value. I would think somewhere between 1 and 2k.
I would start it up, warm it a little by driving around the block and then let it idle and warm up completely and watch if and if so from where the coolant comes.
If it's a serious problem, like head gasket, I would not pay much because you may need to change the engine which will cost you 500 - 1000 plus the labor to do it. It might be better to part the bike out and sell the farkles, wheels etc.
