Take your mirrors off and go for a spin and see what happens. I did. Look at the shape of the back of the mirror. My thought is the mirror is splitting the air from the shield and forcing it back to the rider. I swapped my mirrors and it changed the air flow. Before and after picts. Don.

Wind coming around the side...

Like Mike5100, I too have tried several windshields and brackets before purchasing the Madstad. Madstad is the only thing that seems to 'mostly' work. I'm also still thinking that 'gap' along the lower side of the shield needs blocking. I wonder if we could contact Madstad and see if they would build a custom shield for us that blocks this area, or is maybe is just about 2 inches wider on each side of the shield. On the Madstad website, the shields *alone* are surely less expensive than the entire kit.

I think this is actually worth asking.

I've mentioned this in several other 'buffeting' issues thread. The National Cycle VStream windscreens have a small wing that deflect air out along the bottom and away from the fairing and out away from the handguards. That in combination with the Batzen screen riser has removed all buffeting.
I used the sport touring version (N20058) but there is an even taller version on their site. I think the key is the shape and the flares at the bottom of the windscreen.
It might save you from having to fabricate your own solutions and likely has the same effect on turbulence.

I have the N20059 and haven't noticed any buffeting at any speed. I ride in summer with the visor on my helmet up, trying to get some air when it is hot - no problem at over 100kph. With no problems with buffeting I see no reason to worry about air dams over the fork tubes.

Yes, I can leave my visor open up to highway speeds with minimal noise and no buffeting.

I put a VStream on my NT700V, after trying a Cee Bailey, and it helped a lot with flow across my helmet.

I bought the sport and the touring (their tallest). I'm 6'1", on rally seat, none of them really worked great for me. They would probably work great for shorter riders. I have the Batzen bracket, and even with that I still get turbulance at the top of my helmet on the highway. The Touring windscreen was annoying cause it was right in my eyeseight.

This one seems better than the Batzen (though much more expensive), easier to adjust, and you can also pivot the top of the screen, which in my case would probably solve most of the turbulance...

ATAS is fine, no buffeting from screen or up through forks. Visor up ok.


Still running in so no long high speed runs yet.

I'm 6'3" and ride my ATAS with a dirt bike helmet with a visor, but no face shield or goggles. I don't notice buffeting. On My VStrom my head was blown around like crazy until I put on a taller screen and a madstad. My FZ-09 was noisy as all get out until I put an MRA screen on it. It all depends on where there is a concentrated or disturbed air stream in relation to your head.
