I have had an issue with mine running on one side for 2 years and haven't figured it out yet and I am a mechanic. In my case it has to be something in the harness I haven't found. Unfortunately I have many other things to do and have not had much time to work on it. My problem started after it sat for a year because I broke my wrist and had to have surgery. If it was one of my antiques it would have been running again in a couple hours at most. I have been looking at Harleys because I can get parts locally, my Triumphs the closest place is over an hour away and I have found I can't get certain things already for my 04. I have been riding Triumphs for over 40 years, never thought I would consider a Harley. Dog, that one side not running sounds like a bad CDI or one going bad. I have an OEM unit that was a Triumph warrentee replacement. It is the bone stock one for the 270 motor. It is just sitting on the shelf in my shop. If that would help sort your engine, let me know.
