I picked up a 1977 CB550 Supersport at a garage sale a few weeks ago. I wasn't really hunting for one, but it caught my eye. I got it running, but it needs a tune up for sure. I did all the basic stuff, oil change, new plugs, adjusted the valves. I tried to adjust the cam chain tensioner, but the lock nut was frozen solid on the screw. Sooo... Off came the head and carbs. The carbs were very dirty, so I guess it's a good thing that I am taking the time to do it up right. Not sure if I want to keep it stock or turn it into a cafe racer. I am concerned about running out of warm weather up here in NY, but this should keep me busy all winter!
