You gotta get the angle right and hight right! I figured it out on my bike with how I like to lean back and sit for long rides! The wind hit the topish of my helmet and kept swooping over my head instead of going right over and creating a low pressure zone right behind it and bloing air from under the sheild OR from hitting me in the face and cousing turbulenceay!
I am looking for a bigger windsheild for the future though. One thats longer and bigger so I can keep more wind off me and streamline the bike more by increasing the angle! I found the bike fastish on the highways with the windsheild put on right!
