Hi, my first post here! Hopefully its not a dumb question :/
When air pressurizing the forks, should the wheel be off the ground or not? Neither manuals specify.
More info:
Two of my CBs ('81 CB650 & '81 CB750C) have air assisted forks and I've maintained the pressure range on both to spec: 10-16 psi
In both of their Clymer manuals, the parts specifying adding the air pressure, differ. On the 650, the front wheel is removed and on the 750 manual the bike is on it's center stand. I'm a literal person, so for pressurizing the 650, I lifted the front wheel off the ground, and for the 750 I put it on it's center stand when pumping up.
Added weight on the forks obviously increase the air pressure, so when pumping I can't assume their pressure readings are consistent when matching to their matching specs. As it turns out, the 750's suspension is decent, and it feels that the 650 is too limp. Simple physics would suggest this.
One final point... Both CBs have clip-on handlebars. This weight distribution to the front is greater since my posture leans forward and my body weight is on the front instead of the center like the manual expects. With this said, I decided to add the max (16psi) to both forks. I'd prefer to go more but I don't want to break the seals.

Thanks!
