And can you measure the amount as you add it? Or do you have to remove the springs and use a dipstick to measure it?
I've been running the Progressive LR springs with 15w Bel-Ray fork oil. 5'8, 190lb, have never bottomed the front end. Definitely abused it though.
If you drain the forks and replace the amount that you remove, you should be fine. Off the top of my head, I believe the book says: 430ml/cc per side, dry.
