steering-head bearing adjusting
The star nut is always visible from the side.
The procedure is in the SM. Basically...Loosen the stem nut and one set of pinch bolts (upper or lower, there is some debate, I don't believe it matters.), adjust the star nut with a thin tool such as a screwdriver or punch, torque stem nut, torque pinch bolts.

What you are trying to accomplish with the fall away test, is to see if the neck bearings are too loose, or too tight. Let's say you disconnect all cables and as soon as you lift the front wheel off the ground the front end immediately flops to one side or the other - your bearings are too loose. Conversely if you lift the front end up and it doesn't fall to one side or the other at all, even with a push; the bearings are too tight. Most bikes should not fall away from center on their own, but should fall away gently after being tapped off center about an inch.
I'm sure youtube has a video on it.

One of the trees has to be free to slide along the length of the fork tubes. I loosen the upper. I also tap the side of the tree in the pinch bolt area with a plastic mallet after torquing the stem nut just to make sure the tubes and tree aren't slightly cockeyed before I tighten the pinch bolts.
I recall seeing a good YT video several years ago. I'll see if I can dig it up.
Other people must like it, too. First result in YT search...
I don't go to this much effort, but also useful:
