A few months ago my bike was running flawlessly when I decided to use it for some light track duty. I removed my undertail and swapped tail sections. Removing the undertail took away the rigidity and support of the ECM and PC unit on top of that, so it was bouncing a bit more.
Rode one session for 20 minutes and was fine but went back out fo the next session and after a lap or two the bike started running intermittenly on/off on one of the cylinders, not sure which one. Been just sitting in the garage since then until last night when I started looking around electrical stuff and found this first, output connector for the R/R.
