This is interesting, but not a problem. If it was, I'd consider wearing a Kevlar kilt .

I've noticed the same thing about the air down low. It mostly seems to get blasted off at knee height, presumably by the effect of the rubbery rubbin nubbin fin on the side there.

Making them out of plastic or even aluminum should not be too hard but matching the color could be.

I think the trick really is getting the size, placement and number of the generators correct.

Red Green was on to something using duct tape. It can be formed like the aluminum foil but comes with its own fastener. BTW be sure to use the real 3M tape. Accept no imposters!

The clear stuff is used to replace windows with.
I personally find that it acts too much like a giant fly trap though.

OH YEAH - i noted those prices. That's because they're TSO'd FAA approved. I've been looking for a source such as for experimental aircraft. I did find some aluminum ones for $2.

These polycarb ones would have been perfect but sadly this co. appears to be out of buisness:

I'm close to breaking down and making them up myself.

You are absolutely correct - size, #, & placement will be critical.

My thinking is a 1" size, 8 per side will be a good start.

Anyone up for taping (w/duct tape of course) strips of yellow yarn all over and getting some one to video drive bys so we can determine how the air is flowing

suspend reality as often as possible

I'm assuming you have an interest in aviation, contacts with aircraft owners or access to airfield?
It could be possible to use prop blast as poor mans wind tunnel. Would be easier than drive by video I'll bet.

Turbulence

Big B - sorry, but this is a head shaking, double-vision affair at 60 mph for those of us afflicted - not a "little" issue.

Allonsye - way to go! Keep up the good work. Looking forward to your results.

I got back from my trip and now sick with flu, so experimentation has been temporarily put on hold. Actually, VG's are used in aircraft to make wind "stick" to surface curvature; normally used to increase stall speed and low speed manuverability. In your application I suspect you're redirecting the air flow which achieves the desired effect.

I was considering some type of "wind wing" such as used on my Gold Wing and other touring bikes to completely send air around rider in cold weather. With that set-up I would have the option of changing air flow, particularly when in hot weather and speeds less than 60 mph when maximum air flow would be desired to keep me cool.

When all else fails, twist the right wrist!

Big B, I've got to agree with the "...head shaking, double-vision affair at 60 mph for those of us afflicted..." comment from WeeVGone. I love my K5 DL1000, but the excessive buffeting originating from "down under" is driving me to consider other bikes.

I found the below info: http://www.markfelling.com/id384.htm

"I made Vortex Generators from 3/4" x 3/4" Clear platic 90 degree angle material used to cover sheetrock wall corners available from Menard's. (Idea from John Finly - Q200) Quantity (1) 8' strip will cover a 22' wingspan canard if placed with 6" centers at a cost of about $2.50, 2 strips for 3" centers. I used metal shears or "tin snips" to do the cutting and rounded off edges / burrs with a utility knife. 34 pairs are needed for 6" centers, 66 pairs for 3" centers."

I've never seen the "plastic sheetrock corner thingies" he's referring to, but I think I may have to check into it...
