Carburetor Tuning Made Easy by COLORTUNE

Carburetor optimum Air/Fuel mixture made easy by using a tool known as COLORTUNE, the basic and simplified ever tool used in a single cylinder engine for real time indication of whats happening inside the combustion.

Provided in the video is what the tool does. It indicates visually the color of the combusted material. Once the spark was created by the plug, it then ignite the mixture. This mixture will tell us what the actual color being generated inside to see also that the carburetor mixture needs tweaking. I know this can also be done by those old trick of hearing engine RPM goes up, and or spark plug color indication. The tool simplify all of that.

Thanks to the tool, Tuning single carburetor made it easy, for me.

A kawasaki FURY 125cc engine in the video is being tweak. It visit my garage for carb tuning. The bike is sluggish and fuel economy was poor. Without altering any at first, i removed the spark plug and installed the colortune plug in it. Started the engine, and there goes the ORANGE color spark visible at the plug window. A mere indication of a RICH side carburetor mixture settings. Without any visual indication, to know what is happening inside, we need to remove the spark plug, see the TIP color, adjust the mixture then run again. (old school died a long time ago). I just need to turn the mixture with this tool and as the engine rpm rises as i turn the mixture screw, so does the color indication inside from orange color turning to BLUISH white which is the optimize color of a near stoichometric mixture a carburetor must have. As easy as it gets.

There are too many who uses the tool. Search all over the net. It might help you too...VISUALLY.
