What are the symptoms of poor exhaust flow in a motorcycle's exhaust pipe?
1 Answers
Symptoms include: in severe cases, the motorcycle may fail to start, while in some instances it may start but struggle to accelerate or exhibit jerky acceleration. The exhaust pipe is part of the engine's exhaust system, which mainly consists of the exhaust manifold, exhaust pipe, and muffler. Typically, to control engine pollutant emissions, a three-way catalytic converter is also installed in the exhaust system. Below are methods to determine if the exhaust pipe is clogged: 1. The sound is somewhat muffled when accelerating sharply. 2. In severe cases, the exhaust pipe may turn red after a few minutes of acceleration. 3. The exhaust pipe can also be removed and inspected using an automotive endoscope. 4. The cylinder cut-off method can be used for diagnosis, by sequentially cutting off fuel to each cylinder to identify abnormal cylinders and damaged components.
