Yeah, I understand the bike is heavily modified. The guy said he had a shop do the work and he non-opped it afterward because he hates the look and he's offered to sell it for rather cheap at $800 or so. It looks like almost all of the stock parts are there including the stock tail section, radiator shroud, and headlight.
I wouldn't be looking to return it to stock, so I am not too concerned with that. I'll probably have some sort of tail section welded back on and replace the seat with a basic flat seat to fit two people. Right now I am a bit short on money, so I can't afford to be too ambitious after getting it running. I would probably set aside $700 or so to get it street legal and safe.
