RedRider Posted March 26, 2023 #1 Posted March 26, 2023 (edited) The Colortune allows you to see the color of your in-cylinder burn so you can set the carb mixture correctly. Not terribly difficult to use but really helps avoid the guesswork. It is essentially a spark plug with a glass rind around the outside allowing you to see the color of the burn. Light blue (IIRC) means a proper mixture. Really works well. Comes with complete instructions. Chances are pretty slim I will ever own a carbureted bike again so I'm letting this go. $50 + shipping.
