Yes, this makes sense. Mirrors are too rarely mentioned as the cause of turbulence and wind noise. I discovered on my '01 FZ1, after switching multiple windscreens to no positive effect, that using CRG bar end mirrors instead of the OEM mirrors almost completely solved the problem. Of course you have to like bar end mirrors, which I ultimately never did. Alternately mirror extenders can sometimes help too, though not a cure-all.
