I don't know the quantity of oil to use, but I can tell you a bit about the air part.
If I remember right, pressure is 10 psi max. More than that and the seals start to leak. Also, best results come from using a hand pump. A compressor will fill too fast in some cases. I would start about 5 or so and adjust from there I think.
Hmm, maybe I should find a cb900 manual since so many use 900 parts.
The ride IS the adventure. The destination is just to get gas!
