According to the Honda web site that opening, at least on the Gen 6s, is there to provide some low speed ventatlation air for the rider. I suppose in Vegas you could put a piece of tape over it to see if really makes any difference.
I beg to differ.. The vent is there to alter the flow of air over the top of the screen and actually gives better wind protection than a solid screen. It's an aerodynamic thingy.:blah: Rod
Got this off the Honda Owners Link web site: http://www.ahm-ownerlink.com/Prod_Main.asp "Air flowing through a central air vent under the front windshield provides cool air to the rider at low speeds and increases rider comfort at higher speeds." Appears we're both right.
