I have a 2009 Kawasaki Vulcan 1700 Classic with a Kawasaki OEM quick release windshield that is 21" high. The wind noise is unbearable. After 2 trips of 10 hours each my ears ring loud for 2 days and I am wearing EAR PLUGS. No adjustment on this windshield. I have tried different helmets both full face and 1/2 helmets (no help). I have fabricated a piece of Lexan and attached it to the windshield with clamps to make it 2 1/2" higher (no help). The only thing that helped a tiny bit was to block the 1/2" opening above the headlight. Cannot use Kawasaki OEM lowers with this windshield. The noise really takes off at 55 mph and above. Makes me not want to ride. Any suggestions ???????????????
