There are several reasons for insufficient fuel supply after motorcycle ignition: 1. Lean air-fuel mixture: This results in insufficient gas thrust on the piston after ignition, prolonged combustion time, and engine overheating. The indication of a lean mixture is poor acceleration during operation. When manually adjusting the choke or pumping fuel, acceleration improves, but without enriching the mixture, acceleration becomes weak again. 2. Poor sealing of the two-stroke engine crankcase: Air leakage due to failed crankshaft oil seal on the generator side; air leakage at the crankcase joint surface; air leakage at the joint between the crankcase and cylinder or incorrect piston installation direction. 3. Reed valve issues in two-stroke engines: Damaged reed valve; incorrectly installed rotary valve causing carburetor backfire.

Will I get points deducted if I stop halfway through driving past a red light?

Driving halfway through a red light and then stopping will not result in points being deducted, as this does not count as running a red light. The traffic rules for traffic lights are as follows: 1. Motor vehicle signal lights and non-motor vehicle signal lights: When the green light is on, vehicles are allowed to pass, but turning vehicles must not hinder the passage of straight-going vehicles or pedestrians; when the yellow light is on, vehicles that have already crossed the stop line may continue to pass; when the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle signal lights or pedestrian crossing signal lights, non-motor vehicles and pedestrians should follow the motor vehicle signal lights. When the red light is on, right-turning vehicles may pass if they do not hinder the passage of other vehicles or pedestrians. 2. Pedestrian crossing signal lights: When the green light is on, pedestrians are allowed to cross; when the red light is on, pedestrians are prohibited from entering the crossing, but those already in the crossing may continue or wait at the centerline. 3. Lane signal lights: When the green arrow is on, vehicles in the lane are allowed to proceed in the indicated direction; when the red cross or arrow is on, vehicles in the lane are prohibited from proceeding.

Do Used Cars Need to Be Depreciated?

Used cars need to be depreciated. A used car refers to a motor vehicle that has been registered with the public security traffic management authority, is still in service before reaching the national scrapping standard or within its economically useful life, and can continue to be used. In English, it is translated as "Second-Hand Vehicle" or "Used Car". Below are methods to check if a used car has been in an accident: 1. Check the glass production date: You can look at the production date of the glass, as normally, glass is not replaced. The glass date is usually in the format of numbers + dots, where the numbers represent the year and the dots represent the month. 2. Check the wear and tear on the frame: If the car has been involved in a major accident, the body frame will have varying degrees of dents and misalignment. Therefore, the extent of wear on the frame can indicate whether the car has been in a major accident. 3. Check the screws: You can inspect the screws on the hood, the radiator support, and the door connections. If any of these screws show abnormalities, it is almost certain that the car has been in a major accident. 4. Check the maintenance records: You can visit a 4S shop to inquire about the maintenance records. Any accident car that has been repaired at a 4S shop will have a system record there.

What Causes the Reversing Radar to Have No Sound Alert?

Reversing radar not producing sound alerts is due to a malfunction in the buzzer. Here is the relevant information: Principle of the reversing radar: The reversing radar emits ultrasonic waves through ultrasonic sensors, and these waves reflect back after hitting an obstacle, which are then received by the ultrasonic sensors. The controller calculates the distance to the obstacle based on the time taken for the ultrasonic waves to be emitted and returned, finally alerting the driver through rapid warning sounds from the buzzer. Main functions of the reversing radar: Accurately measures the distance between the rear of the vehicle and the nearest obstacle; emits rapid warning sounds when reversing to the limit distance to alert the driver to brake; repeatedly emits voice warnings to alert pedestrians.

What Does Insufficient Engine Oil Pressure Mean?

Insufficient engine oil pressure indicates that the engine oil is too thin, resulting in oil pressure below the standard value. The lack of engine oil may be due to low oil storage, which requires timely replenishment to avoid insufficient oil pressure. It could also be caused by overly viscous oil, preventing the oil pump from drawing in the thick oil, leading to insufficient oil pressure. In such cases, the oil needs to be replaced. Engine oil, or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers, mainly used for lubricating internal combustion engines.
