Out of curiosity, where exactly does the pair valve "port" exit within the exhaust side of the cylinder head?

Is it right at the end where the header meets the side of the head or near where the exhaust valve opens inside?

It's on the middle of the valve cover.

Thats where it starts but I'm talking about where it exits within the head

Here are some pictures of how the system works. It injects the air into an exhaust port.

Thank you! So this looks like an older design but I'm assuming its the same for the Gen 6 bikes. Looks like it exits right at the exhaust port and not where the header meets the cylinder head.

I don't know if it uses both exhaust valves. There wouldn't be much reason to do so..... but this is the general idea. An idea that really didn't need to be updated or changed.
