KZ1100A3 Air shocks specs

I´ve OEM rear air shocks in my KZ1100A3, but when handling they have lost some oil from the air hose. Can anybody help me with some specs of this shocks, air pressure? oil level? Can I fill some oil again by the hose??

I think that's what I have on my bike, they say air pressure should be like 7 psi. Don't know about the oil. I don't even know what the adjustment knob settings are, wish I did! If you are losing oil from the air hose I'd think you have a leak though. I'd take all the threaded fittings apart and teflon tape them.
