So I finally bought a tall windscreen for my GTS250. I was tired of being cold in the morning. I got the Faco tall windscreen from scooterworks.com
I am very happy with it. The screen does not act like a "sail" as I have read in previous discussions, except in speeds in excess of 75MPH. Here are my pros and cons...
PROS - (1) rode in 40 degree temps and was warm as can be (2) much quieter, I accually heard my motor at 60mph! (3) I can now ride without glasses or goggles (4) It does not look nearly as goofy as I imagined, I kind of like the look. (5) There is a higher top speed, and has less shimmy at higher speed. I had to keep checking my speedo to make sure I wasnt speeding too much.
CONS - (1) fitment around the headlamp is not ideal, it is a close fit and if the screen shifts it makes a horrible squeek, which in turn will wear through the paint. I have temporarily used some felt tape at the contact point, but will eventually file down the screen... (2) There is a whistle around 65MPH but it is not unbearable (3) The screen does not protect the hands that well as the picture suggests, my fingertips get cold easily.
I hope this helps anyone planning on purchasing a tall windsreen, I know it was difficult to finally pick mine.
