Power valve arm GasGas EC 123 05

[Wilmer]

Hello, I'm going to change a gasket on my GasGas EC 125 05. The gasket I'm going to change is the clutch cover gasket. So I'm going to just take the side of and change the gasket and then put everything bak on. I've come so far that the side is now lose but I can't take it of bacause the powervalve arm sits on the clutch cover. My question is how can I get it of? I'm a little bit afraid of the power valve ''settings''. With settings I mean how mutch the power valve moves and so on. I don't have any knowledge of power valves.

Here is a few pictures so you can se what I mean.

If you wonder why there is no nut on the powervalve arm is because I took that of and tried to do it that way but that didn't work...
