Why Does a Motorcycle Get Louder the More You Ride It?
2 Answers
Motorcycles get louder due to foreign objects or an increase in the vehicle's own faults. Below is an introduction to the reasons why a motorcycle's sound becomes increasingly louder: 1. Causes of the noise: Noise is generally produced by vibration, collision, or friction of objects. If a motorcycle's engine is working normally, the sound during operation is minimal and harmonious. However, when the engine malfunctions, abnormal noises occur. 2. Common faults causing noise in scooters: (1) Loose timing camshaft bearings. (2) Severe wear on the working surfaces of the timing cam and valve rocker arm. (3) Broken rear clutch spring. (4) Improper belt selection or clutch acceleration lag, resulting in the sound of the belt hitting the casing. (5) Severe wear of the front clutch pulley weights. (6) Wear of the electric starter clutch (the abnormal noise is more pronounced during electric starting). (7) Incorrect ignition timing, causing the sound of valves hitting the piston (commonly seen in vehicles after maintenance).
From my over ten years of motorcycle riding experience, it's common for motorcycles to get louder over time. The main reasons include aging of the exhaust system, air leaks at exhaust pipe connections, or rust inside the muffler. Exposure to wind and sun over time can cause air leaks, making the sound much louder. Additionally, wear and tear of engine components, such as loose piston rings or increased valve clearance, can lead to more noise during operation. A loose or dirty drive chain can also cause clanking sounds while riding. Long-term neglect of maintenance, such as insufficient lubrication, can exacerbate component friction. If you continue riding, not only will the noise increase, but you may also risk engine damage or even a breakdown on the road. I recommend checking the chain tension and changing the engine oil every quarter, and stopping to inspect immediately if the sound gets louder. Prevention is better than spending money on repairs.
