Reasons for Engine Stalling When Accelerating While Idle is Normal

[VanGia]

The reasons for the engine stalling when accelerating while idle is normal include: the mixture in the engine being too rich, causing stalling; or the mixture in the engine being too lean, leading to stalling. Below are the expanded details: Engine stalling due to overly rich mixture: Simply put, an overly rich mixture in the engine means there is excessive fuel injection. Common causes for an overly rich mixture could be a faulty oxygen sensor or inaccurate air intake measurement. When this happens, the motorcycle stalls, usually due to ignition system failure or fuel system issues. Engine stalling due to overly lean mixture: An overly lean mixture means there is insufficient fuel injection. If the needle seat and foam tube fall into the fuel pool, the needle won't rise with the plunger, thus failing to supply enough gasoline. This makes the mixture even leaner, likely preventing ignition of the mixture, naturally causing the engine to stall during operation.
