Keith, Welcome! You definitley found the right site for are your questions. I'll start by answering your Roadster Screen question. I also have one and experience the same affects that you do. I have seen a mod done on another bike where they made new brackets where the shield fastens to the top of your forks.The brackets were made longer to push the angle of the shield up, thus moving the wind flow higher above your head. I rode the bike and there was quite a difference. there's also other things you can do also, just take a little time on this site and research it for other options. There's a nice
tool kit on
web page Enjoy and Ride Safe!
