Plexifairing GT for 919
For those who are considering a Plexifaring GT for your 919, be aware that the lower glass "legs" of the shield are intended to tuck behind the turn signals. While this works, it is a tight fit and limits the flexibility of positioning the shield.
To make it work for me, I cut off about 2 inches of these lower legs so that there would no longer be any part of the shield behind the turn signals. This gave me flexibility to tilt the sheild back a few degrees. This allows me to tune the airflow better to my liking. Cutting was easy. Just carefully used a coping saw with a fine blade and then smoothed edge with dremel and a sanding drum.
This shield is pretty big. It cuts such a big hole in the air that it creates a large low pressure area in front of the rider. At 70mph +, this low pressure area was so great that it actually pulls the rider forward!
Doing the cutting and tuning described above allowed me to reduce this low pressure area considerably.
