The "The Riders Magazine (29th July)<http://www.ridermagazine.com/top-sto...irst-ride.htm/> review of the 2013 Burg mentions " Holes were added to the lower edge of windscreen to reduce turbulence, but the screen flutters at high..." The 'back of the neck' turbulence on my K7 Exec. (with a Givi D263 ST) is excessive at whatever height the screen is set. Can anyone confirm that "holes at the lower edge" reduce turbulence? Presumably the holes allow air through to reduce the low pressure behind the screen and thus reduce the amount of air rushing back to fill the void? If so, please give me the specs for the holes - diameter (mm please), number of holes, specific location in relation to bottom edge/support brackets etc. Any useful comments/recommendations would be welcome before I start boring.
