Gentlemen I can tell by your air loss after filling that you guys aren't using the Harley Air pump. This is the only tool that should be used to air up those shocks. This pump has a zero loss feature when you disconnect it from the shock. You have a $20,000 bike pony up for the HD air pump.

I ponied up and it still loses a lb. when I unscrew it. I say a pound because by the time I get it hooked back up it's down 2 lbs..... Hiss on, Hiss off.
