What are the symptoms of a motorcycle engine misfiring?

[StDelaney]

Motorcycle engine misfiring symptoms include severe engine vibration. Specific manifestations of motorcycle misfiring: Observe the exhaust pipe outlet; the exhaust gas flow shows obvious intermittency, accompanied by severe exhaust pipe vibration, and a distinct "popping" sound can be clearly heard. The main symptom of misfiring is severe engine vibration. This occurs because one or more cylinders are not functioning, disrupting the engine's balance. When the crankshaft reaches a point where a cylinder should ignite and produce force to push it, the absence of this force causes the speed to drop. When the next cylinder ignites and provides thrust, the speed increases, leading to unstable RPM and engine vibration. Causes of motorcycle misfiring: The most common cause of motorcycle misfiring is a damaged spark plug, which fails to ignite, preventing the cylinder from burning and resulting in misfiring. Another possible cause is a faulty fuel injector, which either fails to spray fuel or sprays poorly atomized fuel, leading to incomplete combustion and misfiring.
