The red indicator is the oil pressure status indicator. When the vehicle switch is turned on and the power is turned on, the oil indicator should be on, as shown in the red circle in the figure after flameout, the indicator will also be on, that is, when the engine starts running and the oil pressure switch is disconnected, the indicator should be off The oil pressure indicator is connected to the oil pressure switch When the oil pressure is too low, the switch closes and the oil pressure indicator lights up Therefore, the oil pressure indicator lights up when the ignition is on and the engine is off.When the engine oil lamp suddenly lights up during riding, stop the engine immediately and check whether the engine oil level is abnormal The pressure sensing of the oil pressure switch is not very accurate. According to the official manual, the minimum speed of the engine that can maintain normal oil pressure is 900 rpm. If it is lower than 900 rpm, the oil pressure may be insufficient, and this oil indicator will not light up, indicating abnormality It can be said that as long as the oil flows under a little pressure, the oil lamp will not light up.In short, as long as the oil indicator lights up when the engine is running, stop the engine immediately and check the oil

Why does oil flow out of the air filter? This is because the cylinder head has a breather valve for crankcase ventilation When the engine piston makes a downward stroke, the pressure inside the crankcase will increase The mixture of crankcase air and oil mist will pass through the cylinder head vent valve. The filter medium in the vent valve separates the engine oil from the crankcase air and allows the air to be sucked out of the hollow bolt of the air filter back plate and into the throttle. The filter medium in the vent valve can not completely block the return of engine oil from the steam mixed with engine oil, and can not be completely sucked into the engine by the throttle. If it accumulates for a long time, it will cause flow.
