Using a vaccum guage

I ran accross "using and interpreting a vaccum guage" at www.secondchancegarage.com/public/186.cfm . This site leans toward vintage cars. Nothing is mentioned in my Clymers about diagnosis with a vaccum guage on my old KZ1000 C2. How come?

Because it has four individual runners instead of a shared intake manifold.

Stick an automotive vacuum gauge on one of the vacuum ports on your KZ and watch the gauge go crazy

I git it! Thanks for the enlightenment!
