Why Do Motorcycles Easily Stall in the Rain?

Common reasons why motorcycles easily stall in the rain include: water ingress causing short circuits in the ignition switch or right-hand kill switch, poor waterproofing of the ignition system's high-voltage cap leading to water ingress, or the overflow tube at the bottom of the carburetor being too long, causing water droplets to be sucked into the carburetor due to negative pressure, resulting in stalling. Precautions for riding a motorcycle in the rain are as follows: 1. Wear a helmet correctly: Always wear a helmet when riding in the rain, but avoid covering the helmet with a raincoat as it can obstruct vision and hinder head movement, making riding difficult. Riders who wear glasses should opt for a helmet with a windshield to prevent rain from wetting their eyes and blurring vision. If water accumulates on the helmet's windshield, simply wipe it off with your hand. 2. Navigating through waterlogged roads: Some roads may have large puddles due to poor drainage or low-lying areas. When encountering such conditions, first assess the water depth, which should be below the height of the spark plug and exhaust pipe to ensure the vehicle doesn't stall while passing through. If the motorcycle stalls and cannot be restarted, push it to a safe area and dry the spark plug and high-voltage cap.

If applied by a motor vehicle recycling enterprise on behalf of the owner, a duplicate of the motor vehicle recycling certificate is required; 5. Original and copy of the motor vehicle owner's identity proof; 6. Application form for motor vehicle suspension, resumption or cancellation of registration; 7. If handled by an authorized agent, the agent's identity proof and copy must also be submitted, and the agent must sign jointly with the motor vehicle owner on the application form for motor vehicle suspension, resumption or cancellation of registration; 8. For commercial vehicles, photos of the dismantled vehicle are required. The vehicle management office will complete the process within one working day if all documents are complete upon acceptance.

How to Forcefully Disable the Engine Lock?

Insert the ignition key into the ignition switch. The stop ECU command receiving coil emits electromagnetic energy, converts it into electrical energy, and temporarily stores it. Used to transmit the key code signal. After receiving the code signal from the key, the receiving coil amplifies it through an amplifier and transmits it to the stop ECU. The stop ECU compares it with the pre-stored identification code in the storage area. If they match, the engine can start.

What are common engine failures?

Common engine failures include: 1. Engine abnormal noise: Engine abnormal noise is divided into cold start noise and hot engine noise. During cold start, the oil pump cannot establish oil pressure and form an oil film immediately, causing parts to lack lubrication and produce noise; 2. Engine carbon deposits: Mainly caused by incomplete combustion during engine operation, combined with gummy substances generated from impurities in fuel and engine oil during combustion, which gradually form carbon deposits over time; 3. Frequently dirty throttle body: A dirty throttle body can cause high idle speed, poor acceleration, and engine warning light alerts; 4. Engine oil burning: Oil burning is usually caused by incorrect oil grade, aging or damaged valve stem seals, piston ring sealing failure leading to oil blow-by, or damaged oil separator/crankcase ventilation system.

How to Dispose of Replaced Tires?

Generally, scrap stations or repair shops will recycle them, and you can sell them for money, but the prices are usually low. It is recommended to hand over the old tires to reliable professional organizations for purchase, as these institutions have relatively complete mechanisms. Do not discard old tires randomly by the roadside or burn them casually. Tires are made of rubber, and if left exposed to the sun for a long time, they will emit unpleasant odors. Burning them is even more unfeasible, as they have a high melting point and produce thick smoke when burned, which often contains a large amount of harmful substances.

What is the normal tire pressure for the 2021 Corolla?

The tire pressure for the 2021 Corolla is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. For the 2021 Corolla, you can check the tire pressure by switching left and right on the buttons located on the left side of the steering wheel. First, press the left or right button on the steering wheel, and then the tire pressure numbers for all four wheels will be displayed on the right side of the instrument panel. Generally, a tire pressure above 2.8 bar is considered too high, and below 2.0 bar is too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates uneven wear on the central tread of the tire, shortening its lifespan; increases body vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of tire components, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to stay on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged while driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new one.

Where is the fuel tank cap switch of Geely and how to open it?

First, enter the driver's seat and then turn off the car. After the car is turned off, shift into the parking gear and then take the key out of the car. Walk to the driver's side of the car, which is the left side, and the fuel tank cap is located there. After approaching the fuel tank cap, gently press the fuel tank cap with your hand, and you will hear a pop sound, and the fuel tank cap will automatically pop open. If you want to refuel, you can proceed to do so. Except for refueling, please do not make any modifications to the fuel tank, otherwise, it may easily cause problems.
