The Road King shocks are air adjustable via an air valve located on the right side of the bike just above the rear tire. Your Harley Davidson owner's manual will tell you what the shocks should be pressurized to depending upon the load on your bike (for instance - if you'll be carrying a passenger - the pressure should be a bit higher than it would be if you were riding solo). Don't even attempt to read the pressure unless you have the specialized hand pump that is used to pressurize the shocks. You can purchase this from Harley Davidson or via a third party online. The valve is a typical bicycle / auto air valve - but ... DO NOT attempt to pressurize it with anything but the specialized hand pump. Using anything else will risk over pressurization of your shocks and that's not good. The shocks hold a very small volume of air at relatively low pressure levels - so the hand pump is a must have.

SOURCE: air in rear shocks
Depending on your weight and if you carry a passenger as to the air pressure. I normally run about 14 but 24 if riding 2 up.
up to 150 lbs- 0
each addition 25 rider pounds > 150 lbs add 1.0 lbs
each additional passenger pounds > 150 lbs add 1.5 lbs
each additional 10 lbs of laggage add 3.0 lbs
Max Pressure 35 psi

The volume is less than about 1/2 quart - it's usually not measured going in since you fill the shock completely - there's no need to measure. Some guys assemble the entire shock, then fill with oil and cycle the shaft, then install the bladder cap last. My method is to install the shaft and seal head and the bladder, then put about 2 PSI in the bladder, then bleed through the compression cap. My method is a bit more complicated to explain, but it's effective at eliminating ALL the air from the oil and it keeps the bladder from being installed in a collapsed state.
As far as the nitrogen charge - 145PSI is stock. 130-160PSI is typical.

here is the table according to h-d a solo rider up 150 lbs. is 0 psi, 150-200 lbs is 0-10 psi, 200-250 is 5-15 psi,with passenger and rider up to 150 lbs is 10-15 psi,up to 200 lbs is20-25 psi, max weight is 20-35 psi good luck ride safely

Hi Patti, Road Kings have air shocks at the rear. You will need a FL touring hand pump and adjust the air pressure accordingly to your weight/load.
