Why Does the Motorcycle Make Loud Noise When Throttling Up?
2 Answers
The reasons why a motorcycle makes loud noise when throttling up are: 1. The loud noise may be due to an issue with the exhaust pipe—check for any cracks; 2. If the throttle response is slow, inspect the carburetor and throttle cable; 3. If the motorcycle vibrates excessively, vibration while revving in neutral indicates an engine problem, whereas vibration during riding requires checking whether the bearings of the front and rear wheels are worn or if the mounting screws are loose. A motorcycle is a two- or three-wheeled vehicle driven by a gasoline engine and steered by handlebars controlling the front wheel. It is lightweight, flexible, and fast, widely used for patrol or passenger and cargo transport, and also serves as sports equipment. Motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.
I remember when I was young and riding motorcycles, I often encountered this situation. When I accelerated, the engine noise was particularly loud, sometimes so much that my ears would ring. This was often due to issues with the exhaust system, such as loose exhaust pipe joints causing leaks, or a corroded muffler that could no longer absorb noise. It could also be caused by a loose or worn-out chain, which would double the friction noise at high speeds. When checking, first find a quiet place, let the engine idle to listen for the source of the noise, or use your hand to feel for leaking hot air at the exhaust pipe connections. A simple fix could be tightening the bolts or replacing the muffler component, which would make the ride quieter and smoother. This kind of noise isn’t just annoying—it could also be a sign of aging parts. If not repaired in time, it might lead to bigger issues, so I always address it early to avoid trouble. Regular maintenance, such as changing the oil and lubricating the drive chain, can effectively prevent such problems. Riding safety always comes first.
