My 09 Deluxe has an 18 inch detachable windscreen and wind deflectors (aka fangs). I still get a little turbulance buffeting over 80 kph. At 110 (I never exceed the speed limit  ) it is quite noticeable and would be really good if I could get rid of it. Any suggestions? I've tried blocking the gap between the headlight and the bottom of the screen but that made things a lot worse. So now I might try changing the angle slightly by putting a 10mm grommet on the bottom mounting bolts to push the bottom out, that should move the top 25mm back. Not much of a change though.

Does anyone have any ideas please.

maybe start with some ribbon to get a better idea of air flow.
