Welcome Ryan. I have one of these little fours, and thoroughly enjoy it. Before you go to the trouble of pulling it apart, I would also suggest you get it running as well as you can, ride it, and enjoy it. It funny how these baby honda fours grow on you. Mine started out in a little bit better condition than yours, i.e. not quite as much surface rust, but it is running well and is a nice little bike to ride. Have fun.
