I agree with "singleminded" that the area he has highlighted is the main issue of air getting channeled up into the cockpit, the gaps in the head light would assist in this issue but IMO only very minor compared to under the headlight. But hey! try it! but i don't think it'll help much. A quick test would be to duct-tape the gaps up, go for a ride down the freeway then pull over (while still on the freeway) and take the tape off and then get going again and see if you can spot the difference.

I find on the days that buffeting is bad... i just suck it up! it's all part of the bike's character.. it's just the same as ya missus - gotta take good with the bad :eusa_shifty:. If i wanted everything to be smooth and wonderfull i would have bought a "Goldwing" :laughing7:

these 2 openings may just create a current drawing enough air to create turbulences.

anyone got a wind tunnel to make some tests ? :D :D

Some great ideas and designs here.
However, I would imagine a degree of air flow is required up through the forks under the fairing in order to fill the partial vacuum created behind the fairing when traveling at speed (which could cause other issues) and also vent enough headwind to help reduce any "barn-door" aerodynamics.
Could definitely do with blocking some of that wind off though!!

after all, a small spoiler on the screen makes a big difference, why a small opening wouldn't make one :)

I'll block them with duct tape to give it a try ;)

how did you go with this Zou ??

I'm of the opinion that the main source of turbulence is from the trailing edges of the screen, which tunnel the airstream directly into the sides of your helmet.Has anyone got not neccessarily a taller version of the screen, but a wider one to deflect air away from the sides of the riders head??

I did consider to attach some WindCOMB along the side and top edges of the windshield, just to see what effect it would have in reducing turbulence. Never tried it...

My screen is scratched so I figure If I wreck it then I will just get an MM screen in a replaCEMENT.

My plan is to drill 4 holes in my screen, near the top in a box pattern to give me a good fixing point then my idea is to get a big sheet of perspex and play around with different designs to see what works best.

My initial plan will just be a small flipper but obviously it will be easy to try a much wider version too.

Using rubber spacers I can also experiment with angles, will post when I know more

http://i1014.photobucket.com/albums/...swan/001-1.jpg I have an xtx and as you can see from the attached photos (one has been on here before), I have made a screen, I initially mounted the bottom of the screen behind the front spoiler and there was a forward suction of my jacket when on the move and some turbulence to the top of my helmet, so I moved the screen forward in front of the spoiler with a gap of about three quarters of an inch at the base, and ay voo as they say in France no suction or turbulence, but my visor when open on first click shuts at about 73 mph without fail. ---- Its probably the pressure behind the z screen thats doing the damage

some have tried this without success...

even without the screen at all, there is still turbulence ..
