Nice find.
Tank alone is worth $200. I just sold my 83 200x A few months back. I had it for over 25 years. I was in the process of restoring it. Engine was in great shape and ran perfect. It was the rest of the parts that were a pain to find and when I did they wanted way to much for them. Tank, plastic and tires was all it really needed but that would of cost me more than I paid for the bike. I ended up selling it to a guy that was restoring the same bike and he needed a motor and suspension parts. He offered me $800 so I took it and used that to buy my Hawk. Ebay has a lot of engine parts. You just have keep checking everyday and you find what you need.
