Jimkost sent me a message about my windshield back in November and unfortunately I just noticed I had any messages. Here's my response for anyone curious about the PlexifairingIII ... Sorry I didn't get back to you. Just saw your comment. As for the fairing slowing me down...I'm not a speed demom. 75 is as fast as I want to go but Hubby has had it over 100 with no problems. My gas mileage is never under 45 mpg city or strong headwind driving. Normal is 50-55 mpg . When we get to ride at higher than the sea level altitudes mileage and performance improve. I've seen 60 mpg several times! My bike is completely stock except the baffles have been punched and the heavy duty springs in the ACCTs. No marbling, ear shaves and no rejetting. It pops a little on decel but that's ok. It let's folks know I'm around! lol I tried a smaller windshield but didn't like it.
