I have used Laminar Lips on several very different motorcycles with some success. They will smooth out the airflow if they are set up right. They must be about the same height as the windshield, but the distance out from the windshield is critical. I place my hand between the lip and shield up to about my thumb, this turns out to be between 1 3/4" and 2 1/4. After attaching, do some testing and fine tune in and out. Anyone else try one of these Laminar lips on the stock windshield?
