I think many people would agree that the stock windscreen on the FZ6R is not great, and the Yamaha Double Bubble is only marginally better.
Previously, I tried cutting down my original screen by about 4" in order to lower the edge of turbulent air hitting my helmet, and that actually worked very well. The wind noise became very reasonable, as did the turbulence, but the wind blast against my upper body was increased. It was a good compromise for going less than 120 kph, but at speeds above that, the wind blast just became too tiring.
I documented this previous attempt here:

So in my never ending quest for windscreen nirvana, I've resorted to another drastic measure. I took my Yamaha Clear Double Bubble and cut a window out of the BOTTOM of it with a jigsaw.
Now why would I do that? Well, I've been researching ways to improve windscreens, and I learned about something called "laminar flow". By arranging air flow into orderly layers as opposed to letting it come over and around a windscreen in a chaotic fashion, it becomes much smoother and less turbulent.
Laminar LLC is a company that sells what they call "laminar lips" which are narrow strips that attach to your windscreen and smooth airflow. This phenomenon is explained on this page of the Laminar LLC website and it's pretty insightful:

On our bikes, you'll notice that behind the windscreen is a black, plastic, triangular area that echoes the shape of the windscreen, but is smaller. I got to thinking that by cutting out an area at the bottom of my double bubble, it would let air flow underneath which would hit this black "sub-windscreen", and the air would be pushed upwards, along the back of the double bubble. This airflow would meet the air coming above the top of the windscreen, and through the laminar flow effect, the resulting air coming off the top of the windscreen would be smooth and less turbulent.
Anyways, that's what I'm hoping. I'll be testing out the modified double bubble tomorrow and will report my findings. Let's hope this strange fix will finally result in a windscreen for our bikes that both looks good and is less turbulent.
Wish me luck!
