K & N FUEL-AIR MONITOR

 
The K&N Fuel-Air Monitor is a precision instrument to help the performance enthusiast with jetting problems. This device will work on carbureted, injected, supercharged, turbocharged, or normally aspirated engines (2 or 4 stroke), unleaded gasoline, alcohol, or nitrous oxide.  It will not work with nitromethane or diesel fuels. The unit indicates lean, rich and correct mixtures using a bar scale. The oxygen sensor fitting needs to be welded to the head pipe collector. With a minimum of 9 volts power supply the monitor can be used temporarily mounted for performance testing.
