Forking hell!

I have a set of rockshox recon silver 100mm travel forks (poploc versions) and have only owned them for about 2-3 months.

They were all well and dandy one say, then suddenly when I went to use the bike again the forks are really soft, and I can't put more than 75psi into them, however I can push the travel to full with little effort.

However the lockout still works how it should.

Have a blown an air seal or something??
Any help is appreciated

    Where is the air you are pumping in going?

    Sounds more like a faulty valve, if anything.

    Honestly have no idea, it does give a big blow off after I remove the pump, so could be the valve?!

    Or the pump. Are you screwing it on far enough?

    Shocks whilst high pressure, are very small capacity compared to say a tyre, so if you getting a blow off when releasing the valve, you could easily be dumping 30 or more PSI, hence soft forks.

    When you say you can't put more thhan 75 PSI, is that with the pump attached, or measuring after youve lost some air removing the pump?

    I know on my fork, an epixon with RS pump, the pump only needs to be screwed on until you feel a tiny bit of resistance on the thread, helps you pull it off quicker with less leakage.

    Thats after the pump has been taken off but the pump won't read any more aswell, I always screw the pump on pretty tight and never had a problem.

    Can you deflate the forks at all so that there is no pressure in there and then pump up to at least a reasonable value just to confirm that the shock pump is actually doing something?

    On the blow off when releasing the valve, I understood that that was just pressurised air in the pump hose, rather than air coming out of the fork? How would you tell if it was coming via the valve on the fork vs from the internals of the shock pump?
