I don't share most bikers' concerns about windshields.
I have generally had no windshield, from 1963 to 1993. In 1993 I bought a CB750 with a huge windshield. I felt as if I was plowing the sky with a bathtub, and I am sure that sail cost me a lot for extra gasoline in 55000 miles.
So I was accustomed to a windshield far bigger than the one on the Wee-Strom, but still familiar with the sensation of having no windshield.
I moved the windshield up to the middle position a couple of days after buying the DL650, and decided I would change it again if I didn't like it. It stayed there for thirteen months, and over 12000 miles, most of that during a long trip from the Great Lakes to the Pacific Ocean and back.
During that trip, I had a lot of crosswinds on I-80. They really tugged at me and made me lean upwind, because my load was so topheavy it was comical. At that time I was unaware of anyone's problems with any windshield on any bike, and I felt no discomfort at all from the windshield. My chief problem was fatigue in my right hand from fighting the throttle return spring. So I held the throttle with my left hand when there was nobody near. No problem.
I changed the windshield to the lowest position a couple of weeks ago, because lots of people have complained about turbulence with the stock windshield, and I want to see what the fuss is about.
Yesterday I rode 150 miles in lovely weather, and I had no problem with turbulence, or anything else for that matter; it was a delightful ride.
I still have no idea what turbulence they are complaining about. Yeah, I notice the wind. After all, I am outside, and that's where the wind is, and when I move, I encounter more wind. I imagine I will notice a difference between the middle and lower positions when I ride through heavy rain, and perhaps I will alter the position again.
I hope Newfoundlander responds to this thread. He is an insightful fellow with lots of experience with no shield, a little with the stock Wee-Strom shield, and lots of praise for a snazzy new shield he got from Europe.
If you will whistle me up a storm, I will go out and paddle through it, and report on my experiences with the windshield at its lowest position.
