In town, at speeds from I'll say 30-50mph in 3rd & 4th gear, I experience that engine thing where it is like lugging then surging. It's hard to explain. I've been told that it's a common thing, but that a Power Commander is supposed to help with it? The thing is, my bike has a PC and it still does it. I've tried experimenting with gear selection, but I don't want to have to keep the revs high all the time to overcome it. Any thoughts or suggestions?
