RM125 1986 Rear Shock Pressure?

[Toolboy]

Gday all,

Currently completing a rebuild of a RM125 1986 and would like to check the pressure of the rear shock.

The shock looks in good condition though I cannot find any info of what the pressure would be???

It would be dry nitrogen that they use to pressurise??

Thanks
