Spartan, the [dedicated] buffeting thread is under the Wee-Strom specific banner. The reason for that has not been made public - I can only guess that perhaps the more powerful exhaust pulses of the 1000cc Vee-Strom are indirectly and beneficially altering the frontal zone airflow, to the extent that few if any Vee-Strom riders suffer from the problem. ;-)
If I may summarize the "buffeting thread" like this :-
For people of middling height, like you and me, riding the Wee-Strom, the stock windscreen usually produces an unpleasant headshake at high frequency - really an aerodynamically-induced vibration (rather than the low-frequency buffeting that you get in an open-top car or even in a sedan with the windows down.
For me, it is a horizontal oscillation which is enough to produce a horizontal blurring of the scenery (at cruising speeds). This spoils the enjoyment of the scenic experience : as well as being mildly unpleasant in itself.
High, middle or low positioning of the stock screen makes little difference.
Riders try all sorts of expensive or tricky "fixes" for the buffeting - with indifferent success.
The most common fix : using the Madstad screen mount to replace the stock mounting points. The Madstad permits the stock screen to be adjusted for angle.
In my own case, I achieved 90+% success, only when the screen was at its lowest position and tilted back as far as it would go.
And there is a problem with Madstad - a problem on dirt roads : it rattles worrisomely when traversing really harsh roads (corrugations & frequent pot-holes). Despite tightening everything to the max, each harsh bump produces a rattle severe enough to suggest impending breakage of the mount/screen - if conditions were to persist.
So I choose to ride "screenless" if the trip involves leaving the bitumen or leaving well-groomed dirt roads.
The Wee specific thread is the one I found. Not exactly thrilled when I read through it.
"aerodynamically-induced vibration" is the appropriate description of it and should be commonly used. The word "buffeting" does not really describe it because most people (including me) associated it with slow frequency side winds. Perhaps here, it had a different meaning because of the common experience BUT to an outside or newbie, it means a different thing.
I was over at Vicious Cycle and tried a few windscreens. I don't like the taller ones because I'm forced to look through them then over them that I do now. I'm not an expert on aerodynamics, I would hazard a guess that the air is breaking up (eddies?) and catching our helmets in it. What I don't understand from reading some post is how it's there at a range of speeds. I would assume that changing speeds would change the shape of the air stream. I do understand that it's complicated to fix because the air stream can change with speed and can be affected by many things.
I'm not going to do anything about it right now because I only felt it for a few second and when there was a rapid change in wind direction. I don't know if it will be present at higher speed or when I'm passing cars or more likely, trucks.
I got it for a few second and was annoyed, I couldn't imagine riding with it for hours on end.
Not thrilled about all this and not what I bargained for......
