I have been averaging under 40 since my ECU recall work. Well, After doing the major service on the bike, I can say that I saw 47 MPG on an 80 mile leisurely country ride. Calculated at the fuel pump. I reset the average when I fueled up prior to the 80 miles and actually saw in the 50s, but that was barely opening the throttle and holding it steady on flat terrain at 50 MPH. When I climbed some long hills the average dropped.
