I make no claims for credit or originality, I found the link to this buried in a recent thread about lyriks, but its such a simple and effective mod it deserves highlighting. If you dont use the floodgate feature, removing it improves the small bump sensitivity and plushness of the fork. It takes a couple of minutes and is reversible.
Couple of points:
SRAM say dont use PTFE tape.
If youre going to do it take the opportunity to change the damper oil rather than syringing out old stuff so you dont lose it. For older forks its 112ml of 5wt, which is an oil level with damper removed and fork fully compressed of 73mm below the top of the stanchion/crown.
SRAM seem to have made similar mods in the newer DH damper by all accounts.
