What Causes a Motorcycle to Stall Automatically?

[VonZoey]

Motorcycle automatic stalling is caused by: issues with the sensor or intake system, requiring inspection and repair at a professional service shop. The four-stroke engine of a motorcycle operates through four cycles: 1. Intake stroke: The intake valve opens, and the piston moves downward to draw in the combustible air-fuel mixture; 2. Compression stroke: Both intake and exhaust valves close, and the piston moves upward to compress the combustible mixture; 3. Power stroke: Both intake and exhaust valves remain closed, and the spark plug ignites the combustible mixture, causing it to burn and push the piston downward, thereby generating power; 4. Exhaust stroke: The exhaust valve opens, and the piston moves upward to expel the combustion byproducts. The four-stroke engine continuously cycles through these four strokes during operation, requiring both fuel and air to function. Without air, the engine will stall.
