I need to sit down and graph the two curves related to air pressure to come up with something the average guy can use. Someday.
For now, basically you take 0 air pressure for a 150 load. Max air pressure for the GVWR of the bike. That will give you are starting place.
The other curve is with regard to road surface. If the road is smooth the second curve is not needed. As the road surface degrades, more air is needed to keep the ride.
Most people just do seat of the pants adjustment. If the rear bottoms out, add more air. If when you have the bike loaded down you now don't see through the same spot on the windshield that you used to, add more air. If the bike gets wallowy in turns, add more air.
