yeeeeeeehhhhhhhhaaaaaaaaaaaaaa! I cut my stock windshield down 3 inches and my mileage went up from an average of 40 to an average of 43.5 MPG...a benefit I was even thinking about : ) this is on the same identical ride to and from work I make everyday...same conditions, same speeds...I feel a little bit of a disturbance high on my head but it is actually helping me keep cooler, and I feel much less wind pushing me where I don't want to be or holding me where I don't want to be...I still look through the top inch or so of the windshield but I can now wipe the fog off when I need to or sit up in the saddle and see over it...I hesitated for a long time doing this but I am sure am glad I made that cut...
