hi guys as the title says how do you tell
is it the colour of your plug eg. the old brown paper bag colour is
what do you guys mean by plug chopping ?

cheers J
 
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
