Despite a tall windshield, the turbulent air is generating some noticeable wind buzz despite wearing earplugs so i thought, raising up the windshield should push up the turbulent air above the helmet.
I have tried bolting it up with L-brackets before, but the setup looked kinda flimsy so i took it off. Searched around for ppl willing to laser cut up some steel or alu plates, but eventually none is willing to do a small job.
So i happen to bump into a guy doing up 3D printing. some communications back and forth on the designs and here i am with 2 piece of risers printed out. Not bad for a first draft, but it raised abit too high up i guess. 8cm from the original mounting hole. i intended to raise up about 5-6cm actually. but anyway i'll just use it for the time being, until it breaks (if it breaks).
rider's view - a lil' bit obscured. so yeah, i might order another pair slightly lower than this, when i cant bear with it any more
Look at California Scientific shields. What they do is relieve the pressure behind the screen with an opening at the bottom. I assume it is engineered since a member here a few inches taller than 6' got one and he said it worked great. You may have a real good idea, but it just needs to bridge the bottom with a plexiglass piece that has an opening size/shape similar to the shield below. Of course, the openings could change with other variables to be perfect, but...
This is also what expensive Goldwings use too, so it must be a proven way to reduce pressure behind the shield. It's also pretty thrifty if it would work: a 3 piece plexiglass set. You could sell them on ADVrider
If I break my Givi Air Flow Scoop drilling on my shield putting it on, then I'll try one of those California Scientific since they have a model for the Vs. 650
The air flow opening is a pretty innovative way to control pressure I'd like to try. Of course I'd like to see the 2010 fairing shield's to see if it is near as fairing-like as on the 2015! The 2015 Vs. 650 California Scientific fits pretty much like a complete fairing kit.
Kawasaki Versys Windshields
The 2010 model screen is not as good cosmetically (but it does have better wind coverage
as the 2015 model, but not bad for the same technology; since it works without Stealth screen edging or expensive deflectors on the top of the screen or adjustable brackets (extra $$$.)
