Why is the motorcycle engine overheating?

Introduction to the causes of motorcycle engine overheating: Overloading operation: Avoid overloading operation and stop to rest, minimizing engine idling time. Adjusting ignition timing: Adjust the ignition timing and avoid setting it too small. Incorrect fuel mixture ratio: Do not use industrial cleaning gasoline without anti-knock agents. Prepare the fuel according to the specified ratio and avoid having too little lubricating oil in the gasoline engine. Adjust the carburetor and fuel mixture ratio to prevent the mixture from being too rich or too lean. Carbon deposit issues: Clean the cooling fins or remove carbon deposits. A motorcycle is a two- or three-wheeled vehicle driven by a gasoline engine, steered by handlebars for front-wheel turning. It is lightweight, flexible, fast-moving, widely used for patrols, passenger and cargo transportation, and also serves as sports equipment.

How to use a newly applied ETC?

Newly installed ETC cannot be used immediately. The ETC device needs to be successfully activated before normal use. ETC activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth On". If "Tag Invalid" appears when inserting/removing twice without the electronic tag attached, this is normal and won't affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth and open the corresponding mobile APP (usually there's a download QR code on the electronic tag), then enter the device activation interface. Click "Device Connection" and wait patiently for the "Connection Successful" prompt. After successful connection, upload a photo of your vehicle's front to complete activation.

What Causes Oil Leakage in Motorcycle Carburetors?

Motorcycle carburetor oil leakage can be attributed to the following reasons: Foreign matter adhering to the contact surface between the needle valve and valve seat: The needle valve and valve seat control the fuel intake and require strict sealing, with high surface smoothness. If foreign matter adheres to the contact surface, it will cause poor sealing between the needle valve and valve seat, resulting in oil leakage. Foreign matter mainly refers to impurities and condensed gum in gasoline. To prevent such faults, users should pay attention to regularly cleaning the gasoline filter and using high-quality gasoline. Needle valve wear: During use, the needle valve wears due to long-term erosion by impurities in gasoline and contact with the valve seat; uneven adjustment at both ends of the float causes the needle valve to bear lateral force and wear. Needle valve wear leads to poor sealing with the valve seat, resulting in oil leakage.

How to Properly Use Lights When Driving in Foggy Conditions?

Methods for correctly using lights when driving in foggy conditions: 1. Turn on both front and rear fog lights; 2. Activate the hazard warning lights (double flashing lights); 3. When visibility is poor, also turn on the low beam headlights. Precautions for driving in foggy conditions: 1. Use vehicle lights appropriately in heavy fog; 2. Pay attention to speed limits; 3. Apply brakes frequently and gently during driving; 4. Use the horn often; 5. Be mindful of the choice of driving route; 6. Pull over to the side of the road when necessary; 7. Utilize defogging techniques for the front windshield; 8. If stranded due to heavy fog, wait until visibility is fully restored before driving. The main purpose of turning on fog lights and hazard warning lights is to make it easier for other drivers to notice your vehicle, thereby avoiding rear-end collisions and side-swipe accidents.

Why is the engine light on and the transmission also having problems?

The reasons for the engine light being on and the transmission also having problems are as follows: Sensor issues: Including water temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to come on. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light coming on. If the owner does not perform regular maintenance and has poor driving habits, it will increase the burden on the engine's operation. Oil quality issues: The oil quality mentioned here includes fuel and engine oil. If the owner does not add gasoline as required, it will cause engine wear over time.
