Tried everything with my recently purchased 07 Ultra Classic trike. Went to a LRS 14 and looked thru the windshield, tried opening and closing the lower vents but their is just too much wind flowing under my face shield. My helmet has a face shield that pushes right up into the upper part. Even tried riding with no face shield. No matter the conditions, there is a lot of turbulence behind the windshield hitting me in the face. Makes no sense as there is the bat fairing and it has deflectors on the bottom part then there is the windshield itself. Think a full face helmet is the only solution.:gah:
