If you tighten the bolts too quickly, in the wrong order, or too tightly, you risk cracking the screen.

How do I properly attach the windscreen to avoid breakage?
About Wind noise
One of the main reasons people try a different screen is to mitigate the noise of the wind coming across the screen. Here is where the noise comes from, listed from quietest to most noisy:
1 Fairing-protected air: Fairing-protected air is the most quiet, but it is difficult to keep completely in the quiet bubble of still air (especially your head/helmet) without crouching low or going very tall on the windscreen.
2 Clean air not stirred up by the fairing: Clean air is not nearly as quiet, but is easy to achieve. For many riders, sit up straight or remove the windscreen and whoomp, there it is.
3 Dirty air: Dirty air is the worst and can cause severe buffeting. Dirty air hitting the helmet is a significant source of deafening wind roar. This is often an unintentional by-product of raising the windscreen to the point where dirty air displaces clean air at helmet level.
Scale on this picture is not intended to be 100% accurate, but it gives a general idea. Different bikes have varying wind flow characteristics, different height riders sit in different positions relative to the airflow, YMMV, yadda yadda, blah blah blah.
