Exploring the wind issue yesterday in preperation for my big trip in June, Did 90MPH indicated for a couple of miles. and the rest at 70 to 80
        
 
         I found it almost a dead calm if leant on the tank behind the screen but will have looked like a teenager on a fizzy
        

 It therefore needs a bigger screen, of that there is no doubt. 
         
        
 My adjustable one is designed but not had time to make it yet so will buy something for the short term.
