Just swapped the stock screen for a mini-euro, and when removing it, all screws on my new bike were from finger-tight to loose. Both the screen and mechanism flex, but I'm sure mine was doing it a lot more due to the loose bolts. Remove the plastic covers, and tighten the middle bolts, but not too much. Just enough that you compress the rubber gasket behind the screen enough for the bolts not to become loose. Then reinstall the covers and tighten those 4 bolts the same way. Whatever flop you have after that will be normal. But expect more than other bikes. Haven't ridden with the mini-euro yet, but seems rock-solid compared to what the stocker felt. It's thicker too. If you want to know how it compares, send me a PM in a few weeks. I don't come to the forums often anymore. Hope this helps man. Good luck.
