This kit, including the Ø52mm Air/Fuel Ratio gauge with its mounting, a 4-wire lambda sensor, and the necessary wiring (only the weld-on nut available on this site is missing), allows for carburetor adjustment across all operating ranges of your engine. Adjusting the mixture screw is useful for idle and emissions for your technical inspection, but it does not affect the full-load circuit. With a reading ranging from 10 to 20, from very rich to very lean, the displayed stoichiometric ratio will allow you to best adjust your carburetor by changing the air, fuel, and progression jets on equipped models.
