Hi all, trying to help a friend with his forks (rockshox dart 2), out riding last weekend and the lockout on the forks seems to have stopped working, leaving the forks locked out constantly. if anyone can shed any light onto why this is and how to fix i would be grateful.

Possible that the cartridge has shifted, try removing the lockout lever and re-fitting it one flat further around so that it’s able to turn a touch further. Other possibilities include all of the oil in the damper having leaked into the lower, causing it to lock, but it’s likely that you’d have noticed reduced travel earlier.
