Set oil level instead of quantity, its easier to make adjustments.
For fork re-build (from 'dry') its between 172.5cc to 177.5cc ( CB900 175cc) ATF
For oil change, 155cc.
Check oil level with springs out, forks compressed and make sure its he same in both legs (probably around 5.5"~6.5")
If you want forks stiffer at 3/4+ travel, increase oil level about 1/2"~1"
