Z200 Air/Fuel Mixture Setting

By BlueKnyght

The technique is based on the Stoichiometric Ratio, which is 14.7:1 or 14.7 air is to 1 fuel (read this). That is for every 14.7cc of air only 1cc of fuel is required to attain the highest combustibility of gasoline w/o being lean or rich. Meaning it is the finest tune for your Motorcycle engine EVER. Yup! It sounded as if you need to have a lot of measuring device to achieve this on your carb. In fact, it is the Stoichiometric Ratio that is being maintained in EFI or fuel injection systems where a lot of sensors is used to tell a computer how to attain the proper air-to-fuel ratio while running in different environmental conditions and loads.
