What Causes a Fuel-Injected Motorcycle to Stall When Accelerating?

[McRosalie]

Here are the reasons why a fuel-injected motorcycle stalls when accelerating: Idle speed too low: When accelerating, the sudden increase in air intake causes the air-fuel mixture to become too lean to ignite, resulting in stalling. In this case, the idle speed can be adjusted appropriately. Choke switch not closed before cold start: Accelerating at this time can also cause the engine to stall. If the motorcycle's choke switch is not open, this situation can be ruled out. Carburetor fuel supply issues: For example, a clogged fuel filter or a damaged float chamber switch can cause insufficient fuel supply. When accelerating, the fuel level in the carburetor float chamber drops, but the subsequent fuel supply cannot keep up, leading to stalling. This type of fault usually results in a brief increase in RPM before stalling when accelerating.
