Not bad, I got an 87 last year for $900, had some similar issues, I spent a
lot of time on ebay, FYI - the gas tank off the newer models will work and
gives you more room and looks good on the bike, here's a link to a
description of what you have to do differently to get it to work, not a big
deal though. I put a newer seat on mine too, much more comfortable, but not
a straight bolt on. ebay usually has seats as well.
I have one I bought back on 2001. Had to put a tank on it because the
original had alot of pin holes in it. I used one off of a '95-'98 honda
ace. It add more fuel capacity to my ride and fits without any mods.
