Just for the fun of it -- proper damping would be shown by pushing the forks down a few times as far as one can in quick succession, and have them rise to no more than their original height. The speed at which they rise is another factor, yet a might difficult for me to describe in words. The best I can say is the desired ascension rate is slightly slower than what one would witness if no oil was in the fork tubes. I know that is a might vague in words.
In that we have no front fork damping adjustment besides spring rate & viscosity,
trial and error is our method. At my weight of 240 lbs, I'm going to try 15 or 20 weight next time. I'm running 12 weight now. With around 15K miles on the fork oil, it's either worn out or way too light, as my forks rebound much higher than their resting spot.
