It does a much better job than the stock and I can still lift it up a notch.

Givi also sent my Air Flow scoop adapter so I can use the air compressing scoop on this screen: but they didn't send any instructions! And it always arrives on Saturday so you can't call them up

I will probably have to put larger nylon screws for the AirFlow scoop added for sure. Just the larger shield says don't go over 62mph in head windsj, which is kind of like flipping a coin on the expressway (the great air channels.) If I get it all sorted out, I'll post the information here. AirFlows screens are the ultimate and you never really need to adjust it for any speeds or any wind direction.
