What Causes Fuel Injection Motorcycles to Experience Poor Acceleration?

Reasons for fuel injection motorcycles not spraying fuel properly include excessively low motor speed, foreign objects between the ball valve and valve seat, and abnormal DC impedance values of the fuel injector coil. Excessively low motor speed: When the motor speed is too low, the fuel pressure in the fuel line cannot reach 200 to 250 kPa (the specified fuel pressure varies by model). Alternatively, if the fuel filter screen is clogged with foreign objects, the fuel pressure cannot rise. It is necessary to check the fuel pump's performance (including verifying whether the battery voltage is above 11V), the fuel filter, filter screen, and fuel delivery lines, and perform repairs or replacements as needed. Foreign objects between the ball valve and valve seat: A common cause is foreign objects lodged between the ball valve and valve seat in the regulator, resulting in low fuel pressure. A thorough inspection of the fuel pressure regulator's performance and fuel lines is required. Abnormal DC impedance values of the fuel injector coil: If the fuel injector coil's DC impedance values are abnormal, it may fail to operate. This can be confirmed by testing its electrical parameters (refer to the vehicle's repair manual for model-specific values). Another issue could be clogged fuel injector nozzle holes. Since fuel injectors operate continuously under high temperature and pressure, they require high-quality fuel. If the user opts for low-quality fuel to save costs, it can lead to deposits forming during combustion.

Does a Rusty Motorcycle Chain Need to Be Replaced?

A rusty motorcycle chain can be either replaced or derusted. Surface rust on motorcycles: When the chrome-plated parts on a motorcycle become worn or corroded by rain, they may develop varying degrees of rust. You can first dissolve ammonium acetate in an equal amount of water, heat the solution to about 70°C, then use a soft cloth soaked in the solution to scrub the rusted areas until the rust spots disappear. Afterward, wipe off any remaining solution with a dry cloth, and the chrome-plated parts will shine like new. Rusty motorcycle chain: First, clean the rear sprocket thoroughly. Spray some cleaner on a cloth and wipe it down. If it's very dirty, you may need to pour the cleaner directly onto the chain and carefully scrub it with a brush, allowing the chain to pass through the brush. After cleaning, remember to apply lubricant to both sides of the chain.

What is the fuel consumption per 100 kilometers for a 400cc motorcycle?

Generally, motorcycles equipped with a 400cc displacement engine have a fuel consumption of 6 to 8 liters per 100 kilometers. Starting: After cold starting the motorcycle, let the engine run for about a minute, then return the choke lever to the fully open position. Do not leave the choke partially closed, as this will cause the fuel-air mixture entering the cylinder to be too rich, leading to increased fuel consumption and reduced engine power. Starting off: Use a low gear to start. Do not open the throttle before engaging the clutch. When the clutch is in a semi-engaged state, gradually release the clutch while slowly opening the throttle to match the engine speed and the requirements for starting, ensuring a smooth take-off. Shifting gears: Master the timing of gear shifting and shift promptly. After starting off, if the road conditions are smooth and unobstructed, quickly shift from low gears to high gears in sequence. If you feel the engine lacks power, quickly downshift to a lower gear.

What is the reason for the front wheels not being able to climb the steps when reversing?

It may be a problem with the reversing method; you should approach the steps at an angle. Observe the ground clearance: It is essential to be familiar with your car's ground clearance. You can refer to the vehicle's configuration table or simply measure the height between the side skirts and the ground with a ruler. Being aware of this can help you avoid the danger of scraping the undercarriage. Reasons for tire blowouts: The occurrence of tire blowouts is often due to drivers forcefully driving onto curbs, which can lead to accidents. This action causes the thinnest sidewall of the tire to bear the force, inevitably resulting in a blowout.

Should You Wash the Car Before Painting?

There is no need to wash the car before painting. Including high-pressure car washing: Removal of dirt such as asphalt and tar, waxing for enhancement and mirror finish treatment, new car wax removal, refurbishment of wheel rims, tires, bumpers, and anti-corrosion coating treatment for the chassis. It also includes external decoration of the car body, such as decorating the roof, windows, surrounding body, and wheels. Automotive paint surface beauty treatments: Paint surface beauty treatments include car washing, waxing, polishing, sealing, coating, and painting. These can be categorized into oxidation film removal, overspray treatment, acid rain treatment, deep and shallow scratch treatment on the paint surface, partial panel damage treatment, and full-body painting. Interior car beauty treatments: Vacuum cleaning and protection of the dashboard, ceiling, carpets, floor mats, seats, seat covers, and door trims, as well as steam sterilization, deodorization of air vents, indoor air purification, interior cleaning, dashboard polishing, leather wrapping, interior deodorizing, and premium interior accessories. Engine beauty treatments include engine flushing and cleaning, application of gloss protectant, refurbishment, and cleaning, inspection, and maintenance of the air filter, fuel filter, oil filter, radiator, battery, etc. It also includes decoration of the driver's cabin and passenger compartment.

How Many Kilometers for a Motorcycle's Second Maintenance?

Generally, the second maintenance for a motorcycle is recommended at 8000-10000 kilometers. Tires: When purchasing, avoid buying tires with overly shallow treads or retreaded tires. It's also advisable not to purchase used tires. New tires are the best choice because tires are made of rubber, which ages over time, significantly reducing tire performance. Additionally, avoid applying oils to the tires as oils have an affinity for rubber, which can easily lead to tire cracking and deterioration, greatly affecting driving safety. Body Shell: Rainwater is generally acidic, and acidic rain can be highly corrosive to metals and plastics. If your motorcycle gets dirty from riding or is exposed to rain, remember to rinse the body with water to mitigate some of the damage from acid rain. Engine Oil: The first oil change after purchasing a new motorcycle is crucial. It is recommended to change the oil for the first time after 500 kilometers, the second time after 1000 kilometers, and subsequently every 2000-3000 kilometers (adjust appropriately based on driving conditions).
