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

[MacMia]

There are several reasons why a motorcycle may make a buzzing sound but fail to start: 1. The battery is old or dead. If the motorcycle doesn't start after two or three attempts, check the battery for issues. 2. In winter, low temperatures may prevent the engine from warming up properly. When starting a cold motorcycle in winter, turn the choke to the highest position, and after about 15 seconds, adjust it to the middle position to allow the motorcycle to warm up. 3. Spark plug failure, which can occur due to prolonged use leading to degraded performance. 4. Check if there is gasoline in the fuel tank. 5. Low temperatures can cause the motorcycle's engine oil to become more viscous, and in extreme cases, the oil may even solidify into clumps.
