What wind noise?
I did try riding the bike briefly w/o the windshield when I changed over from the stock to the taller one - nearly blasted myself off at 75mph and the noise was LOUD. There is sure to be a lot of wind noise however you look at it, because there are so many variables (windshield type, body shape and size, jacket type, helmet type, air density, wind speed and direction). I have more wind noise with the taller wind screen than with the stock, but less buffeting on my head because I'm short (5'7"), which is a trade-off I can live with. A good pair or earplugs makes all the difference, regardless of helmet type. Actually, I feel the fz is the quietest sport-type bike I've ever ridden.
