Another one about Risse Genesis shocks

[zonoskar]

In my Rocky Mountain Edge TO I have a Risse Genesis shock that doesn't have the correct pressure and also there's air in the oil chamber. I found some manuals about how to service the shock, but I don't see a valve to deflate the shock. I took some pictures of what I think should be the valve, it might have snapped off?

Or is this something weird/obscure? I expected a shraeder valve of some sorts. I tried sticking a screwdriver in there, but it wouldn't budge. If I press something pointy in the hole, it appears to bounce, maybe there's some rubber in there?

I thought it was a schraeder valve to pump these up. Might be an older/modded football needle type port. Looks like the shock shaft has been sanded/abraded previously. I can see many fine scratch marks at diagonal angles in the pictures? Maybe the reason for the air loss?

I think the scratches you see are not real scratches, at least I cannot feel them and they are not real obvious on sight. I think the flash of the camera just highlighted them.

The air valve is the old football needle type, make sure you lube the needle when trying to inflate it. I have this type of valve on a Lawwill leader fork fitted with Risse shock, It didn't hold air for long, so I made some new valves using cured Sikaflex & I've not needed to add air for well over 2yrs.

So it's like the Rockshox Mag21, right?
