Mike: I'm near Elmira.
Remove the two lower windshield mounting screws. Go to a hardware store, and find longer screws. While there, get two nylon spacers with center hole large enough for the screws. Spacers should be at leat 1/2" long. Reinstall with the spacers underneath the windshield. That will tip the windshield forward at the bottom, and back at the top. It will also allow more air underneath the windshield, which allows the airflow to "attach" to it. That may not be the correct explanation in fluidic terms, but you'll see the effect immediately. That experiment will cost a whopping $3.
You'll probably want to put the windshield in the highest setting after doing this, because the top of the windshield will now be lower.
You can do this with the original windshield, or any of the available options. I use the Windstrom, which looks like a backwards curve (the edges are forward, not back), and it works great. Zero buffeting.
You can spend more and buy the Mastad adjustable bracket to accomplish the same thing. To be fair, the Mastad will give you more adjustability.
