I have a pump I will sell you cheap!!! I took the POS shocks off my bike. Worst shocks I have "EVER" been on. Reminded me of my hardtail Knuck. I had Terry Cable shocks installed at Sturgis. Fantastic. Almost got Ohlins but glad I didn't. Made the ride home so much better. Cant believe Harley puts that kind of crap on a new bike. That's my rant for the month.

 

i have a Bagger-Werx 07-012 hand pump from amazon. Very good product. It won't loose air when you disconnect it and it won't over pressurize your shocks around $38.

 

If its going from 0-50 in less than a few pumps you either have a block somewhere (hoses not connected to shocks) or you haven't screwed down the fitting enough from the pump on the receiver.

More than likely its not attached enough and you need to screw it down some more. The other problem would likely cause you to pump forever and never get there.
