The windscreen on my Vectrix is too short to block the wind noise for my height. I noticed that when I ducked behind the screen, the noise was reduced significantly. Vectrix said nobody makes a taller windscreen for the bike, so I rigged up an extension. I clamped a clear helmet visor to the top of the windscreen with two sliding door/window locks from Home Depot. I had to hacksaw the locking pins to fit both plastic pieces inside the clamps. It looks fine and is rock-solid at 62 MPH. Now my ride is much quieter and less turbulent. Pictures are posted in the Photos section of http://autos.groups.yahoo.com/group/VectrixRiders/.
