Hello and
Buffering?
Do you mean Buffeting? as when your head gets bashed around by turbulence.
Windscreens must match the size of the rider. So you may need to change the angle by adding a screen extension, or a taller screen, or a shorter screen. The standard mirrors do not help and many riders fit smaller mirrors on lower fittings ( Aprillia style). Some get away with packing out the upper or lower screen fittings with tap washers. On my K7V I fitted a "slipscreen" it was huge and it was fugly and only a little better.
