Just got back from a 3 day 550 mile ride. 4 of us rode some sweet roads along the northern tier of Pa. It was great weather and the kind of ride I dream of in the winter. All Harleys but my RG outshined them all on gas mileage. I was getting 45 mpg with my built motor. One buddy couldn't believe I did better than his stock motor Road King. When I told him I was running a 30 tooth tranny pulley, he just rolled his eyes in disbelief. I wish all rides were this good.
