I never did any full throttle dyno testing and would need an MPGuino to really measure what is happening at part throttle cruise speeds. removing the air box cover was one of the first things I did to the bike so I don't even really have any comparison with fuel economy. Don't know if it helped me, hurt me, or just allows more noise to escape. Looking at the cut away photos of the engine again, it is a long way down through the throttle body to the valve. With the stock runner that is there, it may already be 14 inches total with the throttle plate near the middle. I will have to stick a piece of wire down in there to measure.
