I don't have any data to back this up, but I don't see how it could not help fuel consumption. The rpms really drop low at cruising speed with the JBS. My foot s barely on the gas at 20mph and close to 1/4 at 30mph. Gas mileage is hard for me to keep up with since I ride hilly, rough stuff with the occasional long gravel road thrown in. I don't ride on a paved road at light throttle long enough to get a good read on mpg.
