Why is the motorcycle engine light always on?

Possible reasons include incorrect valve timing and poor sealing of intake and exhaust valves. Below is relevant information about engines: Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. External combustion engine: An external combustion engine means the fuel burns outside the engine. Internal combustion engine: An internal combustion engine, or reciprocating piston engine, differs most from external combustion engines in that the fuel burns inside it. There are many types of internal combustion engines, with common gasoline and diesel engines being typical examples.
When the motorcycle engine light stays on, I immediately think it might be a sensor issue. For example, the oxygen sensor monitors whether the exhaust system is functioning properly. If it gets dirty or fails, the signal becomes inaccurate, and the light stays on as a warning. It could also be due to clogged fuel injectors or worn spark plugs, leading to irregular ignition. The Electronic Control Unit (ECU) stores error codes, so it's best to use an OBD diagnostic tool to check the specific issue instead of guessing blindly. Delaying repairs not only increases fuel consumption but may also damage the engine. I suggest fellow riders start with simple checks: ensure stable battery voltage, fresh fuel, and secure wiring connections. If the light remains on, take it to a technician for inspection immediately—don’t delay, safety comes first. Regular maintenance, such as changing air filters and oil periodically, can prevent problems before they arise.
