What is the Colortune?
The Colortune has a clear spark plug that lets you look
into the combustion chamber while the engine is firing. The
colour of the combustion flame tells you if the mixture is
correct. With the carburettor mixture screw you can then adjust
the flame colour to get the correct mixture.
The Colortune has colour charts and comprehensive instructions
to carry out the job effectively. An effective flame colour
- diagnosis section is included in the booklet. Comes complete
with periscope for recessed plugs.
Take the guesswork out of engine tuning with the Colortune.
The world famous glass topped spark plug that gives you
a window into the combustion chamber so you can see the flame.
Why is this important? The flame's colour tells you the
richness of the air/fuel ratio. A yellow flame means a rich
mixture and a blueish white flame a weaker mixture. Usually
a bunsen blue flame is spot on.
The Colortune is so simple that anyone can use it. It works
on the principle that certain fuel mixtures burn with a certain
color.
The Colortune will work on both motorcycles and cars with
carburettors. Just adjust the mixture screw to get the correct
flame colour.
Also works on injection systems that have a mixture adjuster.
Mainly older injection systems.
The Colortune comes in 3 spark plug thread sizes.
