What Causes Fuel Cut-off in EFI Motorcycles?

The reasons for fuel cut-off in motorcycles are as follows: Fuel supply system failure: If the motorcycle gradually slows down while riding, the engine slowly shuts off automatically, and there is a noticeable lack of power before shutdown, it is generally a fuel supply system issue. In this case, check whether the fuel in the tank is exhausted. If there is sufficient fuel, check whether the fuel switch is turned on. Cylinder head gasket damage: If the engine makes a loud "popping" sound during shutdown and cannot be restarted afterward, and the kick starter feels very weak in compression, it can be determined that the cylinder head gasket has been burned through or the crankshaft oil seal is damaged. Remove the valve cover for inspection. If the cylinder head gasket is damaged, replace it with a new one. Oil seal damage: If the cylinder head gasket shows no signs of damage, check whether the crankshaft oil seal is damaged. Remove the parts outside the crankshaft oil seal and take out the oil seal for inspection. If the oil seal is damaged, replace it with a new one.

Is 60 km/h considered fast for a motorcycle?

On flat roads, 40-60 km/h is the economical speed range for motorcycles, offering a balance of safety, fuel efficiency, and minimal wear on the vehicle. Most standard motorcycles can reach speeds of 80-120 km/h. Racing motorcycles can exceed 300 km/h, while scientific test motorcycles (specifically designed for speed testing) can achieve up to approximately 700 km/h. Additional information: The break-in period for a new motorcycle is around 1,600 kilometers. Oil change intervals: During the break-in period, keep speeds below 45 km/h for the first 500 kilometers and perform the first oil change. From 500 to 1,000 kilometers, do not exceed 55 km/h and change the oil a second time. From 1,000 to 1,600 kilometers, keep speeds under 80 km/h and perform the third oil change. After this, change the oil every 2,000-2,500 kilometers. During normal operation, it is also advisable not to exceed 90 km/h.

Should You Apply Tint Film to a Sunroof?

Sunroofs are generally made of tinted glass, which already provides some level of UV protection. Applying tint film to a sunroof can increase the glass thickness, and if not installed properly, may lead to difficulties in opening and closing the sunroof or affect its sealing performance. Therefore, it is generally not recommended to apply tint film to a sunroof. Here are the details: Standard Sunroof: For a standard car sunroof (not a panoramic sunroof), it is advisable not to apply tint film, as the glass usually already has UV protection and heat insulation properties. Adding film would be redundant and may even distort the light coming through the sunroof. Additionally, the increased glass thickness from the film could cause operational issues if the installation is not done correctly. Panoramic Sunroof: However, for panoramic sunroofs, applying tint film is recommended. Due to their larger surface area, panoramic sunroofs absorb significantly more heat—two to three times more than standard sunroofs—making it necessary to control the temperature inside the car. That said, not all panoramic sunroofs are suitable for tinting. If the sunroof glass is already tinted, avoid colored films to maintain the vehicle's aesthetic. Similarly, if the sunroof has black enamel dots, refrain from applying film.

What Causes the Locking Phenomenon in Electric Tricycle Brakes?

Tricycle brake locking indicates that the brakes are too tight. Here is relevant information: Drum brakes: Two semi-circular brake shoes are installed inside the wheel hub. The "lever principle" is used to push the brake shoes, causing them to come into contact with the inner surface of the hub and generate friction. This produces sufficient friction to reduce the wheel's rotation speed, achieving the braking effect. Disc brakes: A brake caliper controls two brake pads to clamp the brake disc on the wheel. When the brake pads clamp the disc, friction is generated between them to reduce the wheel's rotation speed, allowing the vehicle to slow down or stop. ABS Anti-lock Braking System: Most modern vehicles are equipped with an ABS anti-lock braking system, which ensures that the vehicle maintains directional control while braking without skidding or sliding. The principle of ABS is equivalent to manually creating intermittent braking, but this intermittent braking technology operates at a higher frequency and faster speed. Therefore, when a vehicle with ABS encounters an emergency, the brakes must be firmly pressed down in one motion.

What are the hazards of starting the engine without pressing the brake?

Except for models with one-button start, most other models can start the engine without pressing the brake. Strictly speaking, starting the engine without pressing the brake will not cause any damage to the car. However, for manual transmission models, if the gear is not in neutral before starting, the vehicle may lurch forward during ignition and collide with objects, causing damage. Additional information is as follows: Starting a manual transmission model with the brake pressed: This is the default operation method. Early manual transmission models could hardly ensure that the gear was in neutral and the clutch was fully depressed when starting. To prevent the dangerous phenomenon of the vehicle lurching forward during startup, it was common practice to press the brake when starting. With the advancement of technology, many manual transmission models now have sensors installed on the clutch pedal, preventing the vehicle from starting unless the clutch pedal is fully depressed. Therefore, current manual transmission models require both the clutch and brake to be pressed before starting. Essentially, automatic transmission vehicles will not experience lurching during startup as long as they are in P (Park) or N (Neutral) gear. However, people have brought the habit of driving manual transmissions to automatic transmissions. Gradually, some automatic transmission models have also been designed to require the brake to be pressed for startup.
