1975 550 K1, renovation underway. Rode it to work since September, now that it is cold I am tearing it down and tuning it up. Runs good, 12,000 miles, homemade manometer being finished, replacing the seat, will repaint soon. I didn't get a great deal on it ($1000) but it came with some extras. Lots of little things being repaired or replaced. Oh do I enjoy working on this bike, and what a great ride!
