A guy I know on A Bandit forum I'm also on, and who is a member here who has a C10 as well as a C14, told me how he had bad buffeting and noise problems with the stock wind screen, so he played around with shortening it and ended up cutting it down to where it's 11.5" from the top of the black area on the bottom of the screen to the top of the screen, and he said worked out great for him.
The screen on that came on the C10 I'm resurrecting is really scratched up, so I am going to first ride it stock and then play around with cutting it down and see what how it works, and if it makes improvements over the stock height screen, I'll look around at buying another screen in better conditions to cut down and use.
Here's a picture of his shortened screen.
