On eBay under Honda 700xx, there is an entire bike being parted out. Engine, frame, plastics.......everything. I'm not sure if anyone is looking for anything but its there for the picking.
If you want it make him an offer. The guys name is Wes , He's a good guy and I have bought quite a few bits of him over the years. He sells good clean parts for differant quads and if he say's good condition , you can take it as being in good condition . Some other Ebay sellers say good and you end up throwing it the scrap when it arrives. I am talking to him at the moment about a few bits.lol @ seller wanting $3k for the engine.
