I've always measured oil level with the fork compressed, springs removed and rebound piston rod fully UP. [my old KX manual shows it this way] My new bike's manual hints at setting the level with the rebound rod in the fully DOWN position but doesn't actually specify. Neither Eric Gorr's nor Race Tech's lit. mentions the [proper] rod position when measuring and the difference in oil levels is 20mm -depending whether the rod is up or down. Which do you think is correct? [These are conventional right side up cartridge forks - KDX 220]
