Given to me by Mickey Dunlap...

Warm your quad up for a 15 to 20 min. Run it wide open with a load on it for 5 to 10 sec. Kill the motor and come to a stop. Pull the plugs out and look for the carbon to be burned off in the middle of the 90* corner of the ground strap. If the carbon is burned down around the corner towards the plug threads it is too lean. If it's closer to the tip of the ground strap it is too rich. Carbon line should be right here. The front is about a half jet richer then the rear which is fine. The white electro show that this #7 plug was a little hot for hard riding and was changed to a #8 that will cool it down 5*. It doesn't matter what color the plug is because with different fuels you will get different colors.
