Just an FYI for folks with Viragos which have the inconsistent problem of running on one cylinder. After a lot of debugging it ended up being a bad TCI unit. I sent it off to ......
Dave's TCI Reconditioning Service

...... I sent it out on Monday and had it back on Friday. He turned it around fast and when I got it back and installed it the bike ran the best ever!! Not a miss. I will warn you to ensure the coil wires are tightly connected. With all the on and off when I was working on it I loosened the connections and that made the problem worse.
Just thought I'd let folks know.
