Has anyone installed a Rifle "Sport" fairing on a 1987 K75 Standard?

I have the BMW accessory windshield on it now.At speeds 60 mph and lower I have no helmet buffeting,

but over that speed it becomes annoying. I have added an extension to the windshield top resulting in the performance

I have now. Without the extension it's considerably worse. Tried a Laminar Lip as well to no avail. I'm wondering if I'm someone

has put a "Sport" on their bike and what the results have been.

Thanks, Tim.
