I am at 50K miles and just drained my fork oil. Two things to note: 1) 10 ounces drained out of each leg and 2) when I went to remove the fork cap bolt, I found them to be quite loose - no where near the requisite 60-70 ft/lbs of torque. As a matter of fact, the left side was merely hand tight. I replaced the old oil with 10.7 ozs. HD SE Heavy weight (15wt) oil.
