This may or may not be of interest to you. When I bought my 1100, got the Silverado pkg. Well, the stock windshield sucked one bout a mile long
The buffeting was horrible! Put on a set of Memphis Shades lowers and they made a 180 difference!
Now I can light a smoke with the ol zippo (at reasonable speed) my ballcap cap don't go flyin off, ect. You get the picture.
Let me add that it took me a few adjustments to get it right, take a ride, adjust, take a ride adjust, till it is right on, just a wee bit of movement changes things a ton. Also, because of the turn signal bars, I ended up with the lowers turned upside down, got em perfect
Good luck with yours, think you will love what they do when you got em right.
