Great write up and photos. Well done & thank you.
OP mentions a very important point about measuring fluid level not counting on quantity of ounces!
FWIW One can dive deeper into suspension tuning by increasing/ decreasing the oil level or changing fork oil weight.
From my memory HD standard oil is 10 weight and HD SE is 15 weight with other brands available in
increments of 2.5 weights up ranging from 5 to 20. Personally, to avoid seal blow out, I would not
raise the oil level more than 1/2 inch. Increasing oil level increases compression (resistance) dampening,
heaver weight oil increases (slows) rebound dampening. Progressive springs are an inexpensive must do IMO.
Again, well done & thank you.

Great points, and be super careful about too much oil, it can lead to chatter or worse, hydraulic lock of the forks.
See a full report on front suspension at this LINK. Good info on what to look for in better ride quality and better handling.
