Exup system Yamaha FZ1N 2007, default position of the valve?

Hello friends, I have recently bought Yamaha FZ1N 2007, and I've have stock muffler on it, with the EXUP system on it. But it seems to me that valve in the EXUP doesn't work properly, can someone please tell me what is the default position for EXUP valve, open or closed?

In the ownership manual says when we turn the ignition on "The operation should be carried out as a 3 second drive in the full open direction, 2 second stop, and 3 second drive in the full close direction", and logically speaking, if the valve need to be back to close position, isn't that a default position?

But on the other hand, everyone on the internet or the forums tell different story, that the valve default position is open?

can someone please help me?
