Just bought a 1975 CB550. It runs pretty good, so far. Looking to do a proper restoration one area at a time, e.g. the front end, the rear, cosmetics, etc. The bike was painted a nice grey with black accent before me. I was lucky the tires, rims seem brand new and the paint is flawless, but it needs a new chain, valve adjustment, carb sync, and some other minor stuff.
I'm sure I'll have tons of questions, so bear with me as I go through my restoration with all the cool forum peeps I'm ready to meet
