I too have had this intermitten problem the last couple of year and it very well could have started about the time I installed the LED headlights. Never really thought about that before.
It is a plausible theory. Some electronics can generate copious amounts of RFI, especially if not designed well. And every headlight kit and electronic gadget is different.
Just remember, in my case, I had no problems at all for years with my front TPS and my particular LED headlights. I am almost positive it was a bad TPS. Won't know for sure until I have several more rides. Since I am in a maintenance mode and it has been very rainy, it might be a while before I can post confidently that it is fixed (and with no relation to the headlights), but I place the odds at about 98% sure right now.
