    Weirdness with Lefty SL lockout

    Hi guys and gals,

    I just picked up a distressed Lefty SL that I plan on having rebuilt. The lockout doesn't work in a way that I've never seen before.

    If I compress the fork suddendly (high speed compression), it locks out close to immediately - say 5mm of travel, with a bit of a clunk.
    If I compress relatively slowly (not painfully slowly, but not super-fast), it doesn't resist at all. Feels like an unlocked fork.

    Normally, when I see failed lockouts, I've never seen lockout working under high-speed compression only. Also, usually there was signifcant compression damping when in the "locked out" position, even if lockout wasn't fully working.

    Any thoughts?

    Sounds like a tired seal on the lockout piston. Oil is weeping past it slowly, hence the slow compressability.....
