If it's white or ash colored, it's lean.

Black or sooty, it's rich.



Aim for a nice tan or coffee color with a even burn ring around the insulator.

^^^^^^HAHAHAHA...funny guy.



From Hondatrailbike's website:



Do a plug chop - run it at high rpms and then kill it and check the color of the plug. Based on your plug reading, you may need to move the needle clip or go with a different main jet depending on if it is running rich or lean. When running properly, it should have a nice light brown plug color. If not familiar with how to read a spark plug or make basic carburetor adjustments such as moving the clip or changing the main jet, we highly suggest picking up a Clymers Manual as it covers these routine procedures.
