From what I see your name has already been drug threw the mud. The fact of the matter is you advertised the bike as something that it wasn't and the only way to make it right is give him his stuff back , take your bike back, and next time know what your selling before you list it for sale. Just because you didn't know what you were buying when you got it doesn't mean it's ok to do the same to someone else. He should be totally refunded and then it's your problem to sort it out with the guy you got it from if your not happy. That's just the fucking way it is.
