What Are the Reasons for a Motorcycle Stalling?

[RosalieDella]

Motorcycle stalling can be attributed to the following reasons: Excessively Rich Air-Fuel Mixture: Simply put, an excessively rich air-fuel mixture in the engine means that there is too much fuel being injected. This is usually caused by a faulty oxygen sensor or inaccurate air intake measurement. When this happens, the motorcycle stalls, typically due to ignition system failure or fuel system issues. Excessively Lean Air-Fuel Mixture: An excessively lean air-fuel mixture means that there is too little fuel being injected. In contrast to the above situation, if the needle seat and emulsion tube fall into the fuel bowl, the needle will not be lifted as the piston rises, resulting in insufficient fuel supply. This makes the mixture even leaner, causing it to fail to ignite.
