We have the new BRP screen and deflectors on Carol's and yes at certain speeds the aerodynamics cause the wind to swirl (ie: goes up and over the top and loops down and back underneath you). This would effectively grab some exhaust odor and bring it back up in front of you and its been noticed also. I have no idea if the amount is similar.
As for the "its a motorcycle its supposed to have wind", I'd perhaps change that statement to "some" motorcyclists like wind. The tens of thousands of Goldwings and full dress Harley Ultra's attest to the fact that not all motorcyclists like wind.
