I don't even think a true NACA duct works here or is even necessary. I'm talking about harnessing the "ram effect" of the air stream to compress air and have it flow faster out of the rear sides, and possibly top, of the windshield to counteract the negative pressure immediately behind the windshield.

The hood is necessary to help gather a large volume of air.

BTW, I found that bending polycarbonate requires some complex techniques. So that's out. I'll see if I can rough something together from something found online.

Sorry if this has been suggested before. I'm around 5'11" and I have no problems with the stock screen whether I'm wearing a full face or a MX lid.

But a friend of mine who is probably around 5'9" and wears the XD lid was having problems. Another BMW owning friend lent him I believe it's made by Touratech, wind deflector that clamps on to the GS windscreen. Problem solved.

I am 5-10, XD, stepped/gel seat on a 05 model, tried the TT thing-no good for me. I just did the 2 NACA duct thing last night. That was pretty easy, but have not taken it out for spin yet.

My screen looks like a cheese grater, I've cut 4 1/2" off but I'm still getting some noise.

Noise Levels
What's the price? In my opinion, severe noise levels. This is a deal killer for me. Whenever I wear the XD behind a short fairing or on an unfaired bike, the noise caused by the top vents is pretty much unbearable. And don't forget, we always wear correctly inserted earplugs when we ride (See the wBW Earplugs and Hearing Protection page). I can't imagine how much louder the noise level would be without earplugs...
