What are the reasons why a motorcycle has electricity and fuel but won't start?

Motorcycle has electricity and fuel but won't start due to: 1. Circuit failure; 2. Fuel pipe blockage; 3. Carburetor malfunction; 4. Dry spark plug; 5. Battery depletion. A motorcycle is a flexible and fast means of transportation, driven by a gasoline engine, and is a two-wheeled or three-wheeled vehicle controlled by handlebars to steer the front wheel. It is lightweight, flexible, fast, and widely used for patrol, passenger and cargo transportation, and sports equipment. A motorcycle consists of an engine, transmission system, running system, braking system, and electrical instrumentation equipment. The transmission system of a motorcycle is composed of primary reduction, clutch, gearbox, and secondary reduction.
I've seen this issue of motorcycles having electricity and fuel but failing to start many times in repair shops. Usually, it's not a major problem, with the key issue lying in the ignition system. Spark plugs covered in carbon deposits or with worn electrodes won't produce sparks, and loose or aged high-voltage wire connections can also be the cause. On the electrical side, fuses are prone to blowing, especially during the rainy season when dampness causes short circuits. Don't overlook the fuel system either; a clogged carburetor or a faulty fuel pump can prevent fuel from entering the cylinder. I recommend starting with the simple checks: see if the spark plug is sparking by pulling it out and checking its color. If there's no spark, inspect the high-voltage wires and ignition coil. Don't jump to compression issues right away; those are rare. For safety, make sure the bike is stable before attempting to start it. Regular maintenance, like cleaning spark plugs and checking fuel lines, can prevent most troubles. Hiring a professional mechanic to fix it with a small investment saves both time and effort.
