I have a Cee Baileys screen on my Strom. It's just a tad higher than the stock S10 screen but no turbulance. The difference may be in the "letterbox slot" that's cut into the lower part of the Cee Baileys. I figured I have nothing to lose by trying a similar slot on the stock S10 screen, since if I can't fix the turbulance it's getting replaced anyway.
Checkswrecks kindly offered to help me with it, since he's done a bit of work making screens before. The tidy part in the pics is his work, the ugly stuff is mine. When we'd finished with his part, we agreed it "passes the 10-foot test". Well now, it just about passes the 20-foot test!
It's hard to say if there is an improvement from a short ride around the beltway, but I get the sense that it's a bit smoother. I think most of the buffeting is coming off the sides rather than the top, and if that's the case this won't do much.
But if it does I have some ideas for cleaning this up and keeping the screen. It may be that I made the hole too big - I'm no expert but I get the feeling that velocity is more important than volume for the layer of air coming up the inside of the screen. So I'll ride for a while like this, play with the size of the hole, and report back. If it turns out to be a good mod I'm sure others can do a much neater job than me...
