What sort of tool is best used to inflate a set of variable dampers? The specs for my '86 FZ600 say to make them between 0 and 14PSI, with a standard pressure of 5psi. They need to be within 1.4PSI of each other.
Simple enough, and I will certainly experiment with different settings, but my question is this: How the heck does one inflate these things with any sort of precision? I've tried a hand pump, and even turned the regulator on my compressor down to 5PSI, and filled it that way. I can get air in, but when I remove the valve an indeterminate amount escapes during the valve release. It seems to be a different amount every time.
The air bladders are so small that even taking a measurement with a pressure gauge drops the pressure by ~30% or more.
There must be a screw-on attachment for a hand pump or compressor or something that lets me close the pin valve before I remove the pump from the valve stem, but my Googling skills have failed me. Searching here yielded no fruit either.
The valves are standard pin-type, just like on the tires.
Any help or links to an existing thread would be greatly appreciated.
