Fox performance 34 became shorter while riding

Hi,

My fox float performance 34 120mm fork had slighly bottomed while going down a hill. Once I was at the end of it I noticed the fork was still working properly but was half the size... it is now ~60mm.
It is a bit more than a year old

Anyone have an idea what might be technicaly the problem before I take it all appart?

Regards

Did you put air in it?

Did it.

Added a few PSIs as it was on the recommended pressure, just to see if it helps.
Then I deflated it all the way to 0 and filled it to the correct psi.

still 60mm.

This is difficult to diagnose not-in-person, but I'll give you a piece of advice:

Let all the air out of the fork, and with the valve core removed from the fork, can you physically compress and extend the fork to its extremes?

If you can't, and nothing else is wrong, you could have air trapped in the lowers (which as an explanation, does not rule out something else wrong...). Using a zip tie, carefully work it past the seals on the fork legs, taking care not to damage them. If you get a small sucking sound and the fork now extends all the way, well, that was it. Again, it doesn't mean there's nothing wrong, just that air got into the lower where it shouldn't be.

probably too much negative air. need to over pressure the postitive chamber so the fork is fully extended. then the air chambers will equalize. once equal slowly air down to release air
