Why does the motorcycle engine fail to start and make abnormal noises?

Motorcycle engine failing to start and making abnormal noises is caused by fuel line blockage and insufficient engine pressure. The following is a detailed introduction to the motorcycle engine: 1. Fuel line blockage: There is a drain screw at the bottom of the carburetor. If oil flows out after loosening it, it proves there is no problem, preventing the need to clear the fuel line. 2. Insufficient engine pressure: Step on the kick starter with your foot to feel the resistance. If there is no resistance, it means the engine is damaged and needs an overhaul. If there is resistance, this cause can be ruled out. 3. Check the spark plug: This is the most common reason for failure to start. If it is blackened or the spark is too large, replacing it can solve the problem.

How to Deal with Blurry Windshield in Rainy Weather?

Here are the solutions for dealing with a blurry windshield in rainy weather: 1. Use the air conditioning system: Turn on the fan and cooling switch inside the car, so that the cold air blows onto the glass, quickly dispersing the fog with fast and direct results. Alternatively, turn on the heating to make the glass temperature the same as the interior. Using warm air to defog may initially make the fog on the windshield heavier, but after a while, the warm air will dry the fog away. 2. Utilize the windows: Open the sunroof or windows to allow air convection inside the car. This helps the interior temperature gradually match the outside temperature, causing the fog to dissipate. If the weather is not too cold, you can also keep the sunroof open while driving to maintain the same temperature inside the car, making it less likely for fog to form again.

How to Solve Excessive Fuel Injection Pulse Width?

Solutions for excessive fuel injection pulse width are as follows: 1. Check if the oxygen sensor and coolant temperature sensor are aging: Excessive fuel injection pulse width usually needs to be considered in conjunction with idle speed. If the idle speed is high and the pulse width is large, it is generally caused by inaccurate signals from the throttle position sensor or coolant temperature sensor. If the idle speed is normal but the pulse width is large, it is usually due to a faulty oxygen sensor. 2. Inaccurate closed-loop data received by the ECU: Among these data, the oxygen sensor and coolant temperature sensor are the main factors, though the intake pressure sensor and throttle position sensor cannot be ruled out. You can use a Bluetooth OBD scanner to check the vehicle's internal conditions or have the data rechecked by professionals at a testing station.
