So I purchased a windshield extension (see picture). Test rode it today and I'm not sure I like it. If I raise the windshield all the way, it cuts out the wind entirely. But I have to look right through the extension, which is wavy/distorted just enough for it to be annoying. Faco windshield is crystal clear but this extension is obviously not made that well.
So I guess I have to choose between noise and view.
FYI, on longer trips, I have earplugs in, so no big deal. But around town and running errands, I don't use earplugs.
