Anyone else now getting pretty bad windshield buffeting with their aftermarket windshield?

[Simon Says]

Ok so the question sums it up, and I know this is an easy one to diagnose. I had an aftermarket windshield on my old V-strom 1000 years ago, and it had a large triangular-shaped cutout at the base of the windshield, and I'm sure that cutout did a lot to reduce buffeting on that windshield, since it was (from what I remember) at least 4" taller than stock. Of course I know that the V-strom was not exactly designed to be a high-speed machine, as long as you kept it below about 70mph, wind buffeting was minimal.

I have the Puig Z-racing aftermarket windshield (Z-Racing Screen - Puig Hi-Tech Parts) on my gen 3 Hayabusa (they only offer one model of windshield height). Puig says its 60mm (about 2.3") above standard/stock height, which is great for me because I'm kinda tall and skinny. However above about 90mph that windshield buffets A LOT. when I say "a lot" I mean its easily bouncing forward and back a good 2-3" continuously. Now I know a few of you are saying to yourselves "ok, first world problems!", while also telling me that this exceeds the legal limit of any U.S. highway by a wide margin. These facts don't escape me, just know that here in rural New Mexico, 90mph is legal-minimum speed limit to maintain a healthy distance from the clapped-out meth-addicts behind the wheel of their barely-running Altima's....

Now with that out of the way, I'm assuming with a great deal of certainty, that drilling a hole in the base of this Puig windshield should alleviate at least some, of my high-speed windshield buffeting. But I'm wondering if anyone with actual-scientific insight and knowledge could chime in. How large should the hole be? What shape should the hole be ideally? Are several smaller holes better than one larger one? and so on.... I'd rather not just start drilling holes randomly on this thing, and then later find out that I've thrown 130$ down the drain.

As always, any knowledge or helpful advice is welcomed and appreciated, I'm very grateful to the Hayabusa community and thank you all in advance!
Thanks again, ride safe, and God Bless !

Oddly enough while watching the Isle of Man I noticed most of their bikes have holes drilled about 2 inches up from the bottom....for what I can only assume is to alleviate buffeting.....

How was the stock windshield for buffeting?

My helmet has a big vent on the top that causes me grief at speed....

Not relative to the drilling of holes in the windscreen, but I added Part #14 (CUSHION (20X20X1) 47123-17K00) from this image to my PUIG windscreen to make things better. Cost was about $4.

i have that same screen, no problems that im aware of, theres no excessive noise or buffeting that i can think of, and yeah its taller therefore all the wind on my chin/throat is mostly gone.

[Nevr enuf]

You’re on a sportbike, you’re going to feel the wind, get over it.

[pcs]

have u tried switching the stock wind screen and see how that feels? im using the same screen and no issues even at speeds close to twice of what you are claiming. what helmet are you using?

[dcnblues]

Laminar flow is what you need to research. Find factory wind screens that used it. Many Goldwings I think, the Honda VFR 800 as well. And I'm sure there will be aftermarket small wings you might be able to screw on to the front of the screen. Hard to troubleshoot without your own personal wind tunnel. But I would definitely think that any kind of small Ridge at the base of the windscreen would cause turbulence flowing up the screen that may alleviate your problem. You could be unlucky and have a harmonic that would make it worse, but I think with experimentation you might be able to fix this pretty easily.

Back to stock as this keeps my head in clean air. If there was a screen that actually worked I would put it on for touring but have not found one. Has anyone tall cracked this?

[Sinister#4]

I went with the $$$$ factory taller screen, its better for tall riders for sure but I wish it was tinted a bit. Would really like a darkish tint "touring" type. Had the same issue on my K1200s tried about 4 different ones but the dang stock one was about the best for buffeting

[KPJ132716]

Got the same one and 9
9% of the time is great ..that 1% depends on the weather that day

[mysticblu999]

I have one of those and I peg the speedo all the time on my turbo gen 3 no problems

[LC4CARL]

When I went to a "sport touring" screen on my Gen 1, the buffeting at very high speeds increased vs the "double bubble." I've decided that I can live with the trade off.

[Busajunkie]

This is a WRS windscreen. Minimal buffeting at "higher speeds" with my AGV K6 helmet. Transparent although it may not appear to be. I've used the Zero Gravity on my Gen 2 but this one is better all the way around, IMHO.

Agree with this. I have the Suzuki touring screen and without this cushion that is on the stock windscreen there is too much play. This solved it for me. Wrapped it half on top, half on bottom to create a tight fit. No more play in the screen.
