'02 WR426 ACV vacuum port question

1 post in this topic

In regards to the following method, I was wondering which port they are referring to plug? Is the port underneath the ACV cover or two of the vacuum hoses/ports that lead into carb near the ACV cover?

Method 2:

If you want to stay with the 75 PAJ (richer than the YZF) you have to open the circuit by leaving in the spring and diaphragm and plugging the vacuum port.
