I'm 93.7% sure that you have the exact same shocks on your bike as my '84 ZN1100. If so, turn the right side adjuster clockwise to reduce pre-load and turn the left side adjuster counter clockwise to reduce pre-load.
The shocks have a usable air pressure range of 8.5psi to 43psi with a mean of 25.8psi. Where you set your shocks depends on your personal preference but to give you some idea, I am 200lbs. (of lovemaking machine) and I like a medium firm ride. I have the pre-load set to 4 with 25psi air pressure. I've played around with the settings quite a bit and this is what works best for me.
Someday, in my dreams, I'll install some good modern shocks with variable rate damping to keep up to the my front forks that have cartridge emulators installed but I think I have to go at least $600 to enter that world.
