I realize that the quantity of fork oil was not the problem, but, for the record, the proper way to ensure you have the correct amount of fork oil in the fork tubes is to measure the fork oil height with the fork spring removed and the forks fully compressed.
According to the FSM, the proper fork oil height for my bike (see signature) is 2.95 inches, or 75 mm.
I've never had the forks apart on my Savage, but here's how I measure fork oil height on my other bikes:
The vice grips keep the ruler from falling into the fork tube. Yep, BTDT!
