What does it mean when the motorcycle oil can light comes on?

[Hallie]

Here are the detailed explanations for the motorcycle oil can light illumination: 1. Excessive oil viscosity: The viscosity of engine oil is related to its quality. Higher viscosity indicates better high-temperature resistance of the oil. Always use the oil grade recommended for your specific engine. 2. Pressure relief valve blockage or improper adjustment: To prevent excessive oil pressure in the lubrication system (which would increase engine power consumption and cause oil leaks at sealed connections), pressure relief valves are installed in the main oil gallery or oil pump. These valves limit the oil pressure to stay within specified values. A faulty pressure relief valve can cause abnormal oil pressure, triggering the oil warning light. 3. Insufficient oil quantity: Reduced oil pump output or air ingestion in the pump can lower oil pressure. This leads to inadequate lubrication between the crankshaft and bearings, as well as between cylinder liners and pistons, accelerating wear. 4. Engine overheating: Excessive scale in the cooling system, poor heat dissipation, prolonged overload operation, or delayed fuel injection timing can all cause engine overheating. This accelerates oil aging, deterioration, and thinning, leading to oil leakage through clearances, pressure drops, and illumination of the oil warning light.
