Hi Sam. There are some good threads around here including a couple stickies on plug reading. A true "plug chop" actually refers to making a test run and then removing the plug and cutting off the threads to look at the lower part of the insulator for color. Personally I just use a flashlight and magnifying glass. Read up!

black=to rich
white= to lean
tan=just right

take your bike out where you can open it wide up

put a new plug in and go wide open thru the gears and hit the kill and pull the plug and check it
