It kind of depends on what type of shield you have. I have a National Cycle Switchblade and it pulls down and forward toward the top of the headlight for removal. It comes off in about 3 seconds but requires a little bit of a larger gap that one that does not pull off.
Big Al is referring to the distance between the bike and the "nearest windshield." He's a purist and won't put one on the bike...
Great joke there man! :lol:
If you think you have too much space you can get some of the smaller foam pipe wrap to fit around the inside edge of the shield to fill in the gap.
