It leans over more on the stand with the air ride aired up, so I air mine down when I park and when I fill the tank. Takes just a second, especially if you're still sitting on it. I have found that if you air it up standing over it, it airs up a lot faster, so I do that before I sit down and take off and always do it with the engine running so it has more juice. I've ridden a ton of miles with it on the bump stops as well, and haven't ever had an issue with the fender (and I've checked it). For the guys who have, maybe they were the wrong stops or not installed correctly? I have a K9, maybe different models need different stops?
It does handle better with the air ride aired up though, I originally got it so I quit dragging my V&H Big Radius pipes. Those are long gone, but I can lean further with the air ride up and always do that before I hit the twistys.
