My RP23 has functioned flawlessly for the last 2 years.
I’ve always been a set and forget – I don’t play with sag or propedal beyond the initial installation.
I’ve noticed now that my sag increases everytime I use it.
I’m either endulging in too many festivities or this thing has a slow leak.
I’m not sure if temperature has anything to do with it either.
I’ve not heard of this before – do they leak?
How can I check before putting it in for an expensive service.
Its never been serviced at all with moderate usage but I did take it to mojo 3 months ago who tested it and said it was working fine.

Check the valve is screwed into the body tight and the removable core is tight (you will need a core remover, they are built into the caps on Slime bottles)

You may find air is leaking between the positive and negative chambers.

thanks will try

You can do an air seal service yourself, seal kits are available from mojo and there’s how to vids on you tube, but as above..check the valve core first

You wonder why it’s leaking but haven’t serviced it in two years? 🙄
It’s to be hoped you haven’t wore the anodising away…these things need to be kept lubed.

It needs a proper service. End of story.

An aicam service/lube will freshen it up, but after 2 years it needs a full job doing. Try LoCo Tuning, they’re better value than Mojo.
