An improper air-fuel ratio can lead to poor engine efficiency, increased emissions, and even engine damage. A rich mixture (too much fuel) can cause incomplete combustion, resulting in higher emissions and lower fuel economy. Conversely, a lean mixture (too much air) can lead to overheating and engine knocking.
For the Kawasaki Vulcan 900 Custom, the optimal air-fuel ratio is crucial for balancing performance and emissions. This motorcycle typically requires a ratio close to 14.7:1, which is considered the stoichiometric ratio. At this ratio, the engine achieves maximum efficiency and minimal emissions, as the fuel is entirely combusted with the available oxygen. Adjusting the air-fuel ratio can improve specific performance aspects, but it should be done carefully to avoid adverse effects.
