    Went for short ride yesterday, topped off fuel (about half tank) @ a gas station ive never used. Got 91oct. unfortunatly 10% ethanol. Rode 48 miles parked it for the nite road 1 mile to work (all normal) and on the way home for lunch began dying when off throttle and surging, but still idles at a stop. Could be bad fuel???? Help plz

    Ok so I had this problem and I replaced my plug wires and plugs so wabamm it fixed it only for a short period of time then it started happening again so I took it in to Hals Harley here in Wisconsin and they connected it to a computer and put it on the dyno and noticed a bunch of values in the ECM were screwed up from just over time and I've rode it for the past month and everything seems perfect.
