I have same issue, 6'4", a1200GS, my seat is much higher than standard
If I tuck in behind the screen there is still loads of wind noise!
By tucking in your helmet is angled so far forward its aerodynamcis will have changed completely, no reference to sitting more or less straight. However, i tried it once, and found noise much lower. I can not believe air travels up from below the beak to helmet level. I think the next point is what the cause is.
Unfortunately it is more or less inherent on a bike of this style as you sit so far from the screen,the air re converges around your lid.
I believe is is the one and only explanation
The noise with the standard GS screen is almost certainly caused by the chin vent. Tape it over with duct tape and it is reduced significantly.
will try this next. It's obvious to me the turbulent flow enters at the bottom of my helmet (system6, or C2). Noticed already it changes significantly when putting my hand in certain positions below the helmet You can easily feel with your hand where the turbulent flow is, just move it uo an down etc in front of you
I bought the custom moulded ultimate ear plugs with built in headphones / I suffer from tinittus
same here, have the ultimate monitors and mild tinittus. Monitors went also back for probably same reason. Now, 2 years later, the right one doesn't fit properly. Shame as I now require new ones, and I don't think they can re-use the speakers. Sound is great though, I once tried a Cardo / speakers / foam plugs, sound wise terrible as it filters all high tones out
