Very true,
Now for the "Air Gap" and why it is actually important (even more so if you run USD forks with the down stops removed)
What it does in the forks is act as an "Air Spring" and when set correctly is what stops the fork travel (or "bottoms" them) before any mechanical bits hit each other.
On standard forks it isn't as critical but if you feel the front bottoming under normal conditions, then raise the oil level 5-10mm
If you don't use the entire suspension travel, lower the level by the same amount.
Keep the adjustments small and write down what you have done so the next time you won't need to do it all again.
This is also why you see the zip tie, or whatever you guys call them, on the fork tube.
It is an easy way to keep track of you total front suspension travel.
Now on USD forks, this is much more critical especially on reworked forks with the down stop removed.
These are removed as they stop the fork travel about 20-25mm sooner than they need.
The down side is if you do bottom the forks without them, you can damage the valves,
Also I find it just too much of a PITA to measure the level in USD forks as it requires taking the cartridge apart to get the spring out and with as heavy of springs that I run and cut top out springs it can be a challenge to break them down by yourself.
So the first time I set the level and kept track of how much fluid was used and now just fill them by volume.
And when you make your Air Gap adjustments, go 10cc at a time and like all things write it down in, as we used to say in the Corps, your D.O.P.E. book (Data On Personal Equipment).
While it can be a bit of a pain to get the gap set right, it is a one time thing and once you have "Your" numbers, you should be good until you mod something.......
