What Causes a Motorcycle to Make a Buzzing Sound but Not Start When Igniting?

[DiHeidi]

The reasons why a motorcycle makes a buzzing sound but does not start when igniting are: 1. The battery is old and has no power; 2. In winter, the engine has not completed preheating due to low temperatures; 3. Spark plug failure, caused by prolonged use leading to performance degradation; 4. There is no gasoline left in the fuel tank; 5. Low temperatures cause the viscosity of the motorcycle's engine oil to increase, and in extreme cold, the oil may even solidify into clumps. The methods to start a motorcycle are: 1. Use the main stand to prop up the bike on level ground; 2. Stand in the direction the kickstarter is pressed—if the kickstarter is pressed forward, face forward and step on it to ignite; 3. If the kickstarter is pressed backward, face backward and step on it to ignite.
