Replacing M5 orifice

[Kurt 14]

I need to install a larger orifice in the M5. I pulled the retaining clip and removed the control knob. I'm assuming I now need to remove the black piece with the two flat metal pieces attached? I have no idea what these parts are called. Sorry.

Does this black piece simply unscrew? Am I on the right track? Better safe than sorry.

Thanks.

Never mind. I found out how it goes in. Goes in from the other end. Duh...One of those days ya know?

I have a m5 andinstead of using those little colored things we just mixed our soap to how it flows.

it is a lot easier
