Why is it such a big difference from my Sportster with no screen? Is it because the wind is concentrated as opposed to hitting you everywhere equally? I never had a wiind noise concern with my Sportster, but the Street Glide had my ears almost bleeding. Yeah, I got rid of that ridiculous 4" screen after some hearing damage...got a 9" Clearview with the recurve feature (great piece). Now, I think I need to change my 3/4 helmet for a half helmet because of the reverb thing going on in it. I also have custom ear plugs (which seem to increase that drumming effect). Face it, I'm confused. Any help would be greatly appreciated.
