my point is dont, its a bad fork, that isnt worth the adjustment. there is no air adjustment, as my friend has the same fork. hey suck. he went of a curb, and bottomed it out...
I've got the same fork and I say just experiment. Put a bit of air in, feel the fork. If it's too soft, more air, too hard, less air. Find a spot it feels good and go for a ride. At the end of the ride if you were bottoming a lot, more air. Get the idea?
