SM 125 clutch problem

So i recently went to switch the front sprocket on my gas gas sm 125 halley 2009 and by mistake pressed the clutch lever while the slave cylinder was off.
Some oil seeped out and i put it back together and have tried to bleed the system multiple times, reverse bleed with a syringe, new oil. Nothing... the clutch doesnt work at all. It feels like normal and has good pressure when i press the lever but it still won't work. I drove it the same day and have been the past 3 weeks. (its the same clutch as in an ec 125 and it uses mineral oil)

Don't know what im supposed to do right now, any help is appreciated.
 
It sounds like you still have air in the system. Air can hide in nooks and crannies like the banjo bolts.

First - I would take off the slave cylinder and tap it lightly while changing orientation with the hose end up to try to shake loose any bubbles so it can float up the hose.

Second - I would change the orientation of the master cylinder so the cover is level front to rear and at a slight upward angle on the outside. We are trying to make it easy for air to come out the hole in the master. With the cover off the master, tap the master cylinder with a plastic screwdriver handle or piece of wood while slightly depressing the clutch lever to see if you can get any air out of the master.
 
Could some part have fallen out? E.g. a small ball?

Its plausible but i didnt notice anything pop out, should there be a second ball that pushes the small rod in the middle? There is a ball on the slave cylinder piston, but that one is stuck there.

We have tried to air the system in all sorts of ways, so right now im thinking its not air in the system but something else.
