2013 Road Glide with no engine mods
I ride a 2013 RGC, about a week ago there was a little bit of surging as I accelerated. My bike was at half a tank and had been sitting for a month. I topped it off with 93 Octane and it seemed to run fine until it got back to half a tank today. The engine light stays on as well. Thinking that it was only bad gas, I siphoned out most of the gas and refilled it 93 and Seafoam. I rode it around the neighborhood for a few and it started out fine but quickly started surging again. The only addition that I have done to it was adding an aftermarket breather last year. She has less than 16000 miles on her and was tuned up before winter storing last year. Does anyone have any idea about what could be causing this?
