Motorcycle engine warning light illumination is caused by issues such as poor valve sealing, fuel pump circuit malfunctions, and intake system blockages. The specific reasons are as follows: Poor Valve Sealing: Incorrect valve timing, leading to inadequate sealing of intake and exhaust valves. Fuel Pump Circuit Malfunction: Poor performance, short circuits, or burnouts in the fuel pump due to circuit issues, resulting in insufficient or halted fuel supply. Intake System Blockage: Blockages in the intake system, such as in the air filter or mass airflow sensor, preventing complete fuel combustion. Engine Detonation: The primary cause of engine detonation is excessively rapid combustion. Detonation generates excessive impact forces on the pistons, causing wear on the cylinder walls.
