bought a used yz125 and the mono shock was blown, i thought.... I read they had nitrogen in them (this one obviously empty) so i aired it up(was going to buy a new one anyways) but its holding air and not leaking it out?

maybe previous owner was a dummy and let the nitrogen out?? and the shock is still good?? the air makes it feal better could use a stronger air compressor though .. any thoughts..i've done front forks but have never messed with a rear mono shock
