I bought a '75 850T last summer and was never able to get it to run well. The right cylinder wouldn't fire at all. Checked all the obvious and a lot of people warned me about peeling chrome, as the bike had been sitting for a number of years. I finally had time today to remove the cylinder. To my untrained eye, it looks great! Can't feel any imperfections in the bore and there is minimal carbon buildup on the head and piston. I don't know if you you can tell from the photos, but does it look like these cylinders are already Nikasil coated. I was hoping to find a nasty mess, buy new cylinders, and ride off into the sunset.
