You need to remove the plastic cap, and push down the metal button while removing the circlip with a couple screwdrivers. It takes a lot of force to push it down. I wedge in a 3/8" drive ratchet with 1/4" adapter and tiny metric socket between the handlebar and the button, and it'll sit there solid while you work around it:

Ok, thank you very much for this tip.

I'll try it this week-end.

What kind of oil use you in your fork ?

Many thanks, infrapista

Also make sure to loosen that upper pinch bolt. It will compress the tube enough to not let the cap pop out.

i use 20w fork oil for 200 lbs bloke
