Shockpump test

 Damn my bad,i naturally assumed that it would take 50 psi to fill the pump regardless of pressures involved.

 It's not just the pressures involved, the volume is the reason for why it won't drop as much. Even if I filled the main air chamber with 200 psi the pressure wouldn't drop more than around 10-15 psi. It's not a certain air pressure the pump have to suck in to read, it's a certain AMOUNT of air. On a big volume chamber that certain amount my pump requires is a lower percent than on a small air chamber, like a piggyback.

 Imagine that the pump needs 50 cc of air and the air chamber on the shock is 50 cc as well. Then the pressure would drop to half (50%) when connecting the pump. If the air chamber on the shock is 150 cc (let's say it's 300 psi), the pressure would drop 75 psi (25%).
