What Causes Motorcycle Fuel Cutoff?
1 Answers
The reasons for motorcycle fuel cutoff are as follows: 1. Fuel supply system failure: When a motorcycle gradually decelerates and experiences fuel cutoff during operation, with the engine slowly stalling and noticeable power loss before shutdown, it is generally due to a fuel supply system malfunction. 2. Engine failure: If the engine produces loud noises during the fuel cutoff and stalling process, cannot restart after stalling, and the kickstarter lever shows minimal compression resistance, it indicates a blown cylinder head gasket or damaged crankshaft oil seal. 3. Incompatible ignition system: Some motorcycles feature dual or multiple cam lobes. Using a single-lobe ignition system may result in normal idle but inability to accelerate properly, essentially causing ignition failure.
