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.

I learned all I need to know about life by killing smart people and eating their brains.
