After reading this thread I realized that I had not yet checked my tire and shock pressures as the Trike is only 3 months old...I know, poor excuse.
Anyway I went to check them, and all three tires and the shocks were well below the recommended pressures. So I first tried a small compressor that I have in a rolling cart. It was kind of a PITA to maneuver it and the trike, plug it in, uncoil the hose, and find the chuck. Then the readings that I got after inflating, adjusting and re-inflating were all over the place and seemed kind of sketchy.
Then I remembered besides the Moto Pump I will carry on the Trike for long rides, I also have an Air Man battery powered hand held digital pump that I have never tried. *According to the directions you can set the pressure that you want, screw the no air loss hose onto the tire valve and pull the trigger. It will pump until it gets up to the the set pressure, and then automatically turn off. To my pleasant surprise...it did just that
easy peasy
Now I am right at 26 on the rears, 36 on the front and about 26 on the shocks, set with a HD hand pump and gauge.
