  • Misunderstanding about the use of motor oil

    1. Less oil is "burning oil"

    Moderate consumption of oil is normal and inevitable. As long as the engine is running, the organic oil is consumed. Normal oil consumption is necessary to maintain the engine operation and will not cause damage to the engine. Note that the engine oil level is frequently checked. If the oil level is found to be below the specified minimum level, the oil should be added in time.

    2. Check the oil condition should be done during maintenance.

    The habit of checking the condition of the vehicle in time should be developed. For the use of harsh conditions, long idle time, frequent stop / start, low speed operation, it is more likely to cause an increase in engine oil consumption, so more attention should be paid to timely inspection and addition of oil.

    3. The oil consumption indicates that there is a problem with the engine.

    There are many factors in the consumption of oil. The viscosity of the oil, the quality of the fuel, the early running-in of the vehicle, the correct driving habits, and the length of the engine idling, etc., all cause different degrees of oil consumption. "Inferior oil" doesn't talk about it (that stuff can't be used at all).

    4. The oil gauge does not detect the oil, indicating that there is no oil in the engine.

    When the oil gauge does not detect the oil, it only indicates that the remaining oil cannot meet the needs of the vehicle. It is necessary to add oil in time, but there is still a lot of oil in the engine. For example, there are at least 0.6 liters of engine oil in the YBR125 engine. So you don't have to panic, but you have to add it.


  • What is the fuel consumption of a motorcycle

    Compared with cars, motorcycles have some "hands and feet upside down": the left hand controls the clutch and the left foot controls the transmission. The transmission is also divided into international gear and cycle gear according to different gear positions.

    The order of the international gears is 1-empty-2-3-4-5, and the neutral gear is in the middle of the 1st and 2nd gears. It is also the image of the 1st and 2nd hooks. This arrangement can effectively avoid misoperations. More common gear order.

    The order of the cycle files is: empty-1-2-3-4-5, up pick is upshift, down step is downshift, repeated cycles, simple and easy to remember is the main feature of this arrangement transmission.

    What is the fuel consumption of a motorcycle?

    In principle, the higher the displacement, the higher the fuel consumption level of the car. Take the 300cc displacement motorcycle as an example. The fuel consumption is about 3-4L/100km. The general model uses 92# gasoline. The oil in a box is about 100 yuan. It can run about 300-400 kilometers. Of course, different brands and different models. There will be some differences, but a motorcycle with a lighter body and a lighter burden can save more than half of the fuel cost of the car.

    Since the weight of the motorcycle is much lighter than that of the car, it is also necessary to pay special attention to parking and anti-theft. When selecting the lock, you can choose the chain lock or the disc lock according to the parking conditions. If it is a large displacement motorcycle, it is recommended to buy. Locks for hydraulic shear pressures above 16T.


  • Different methods of motorcycle classification

    Different countries have different methods of classification of motorcycles. International standards (ISO3833-1977) divide motorcycles into two categories according to speed and weight: dual-purpose motorcycles and motorcycles. There are two types of classification methods for motorcycles in China: one is divided into mopeds and motorcycles according to displacement and maximum design speed. The moped engine has a working volume of no more than 50 ml and a maximum design speed of no more than 50 km.

    The motorcycle refers to a two- or three-wheeled motorcycle with a working volume of more than 50 ml and a maximum design speed of more than 50 km. The other is divided into two categories: two-wheeled vehicles, side tricycles and three-wheeled vehicles according to the number and position of the wheels.

    It is customary to categorize by application, structure and engine type and working volume. If you only work in the city, a short-distance travel tool, choose a miniature motorcycle or moped with a compact speed of no more than 50 kilometers. Need to travel frequently between urban and rural areas, can ride two people, should choose an ordinary motorcycle with an engine working volume of 125 ~ 250 ml. If the road conditions are poor, high speed driving or general competition is used, the off-road motorcycle is used.

    According to the core configuration of the engine and clutch, different models have different classifications. This is like the turbine engine or dual clutch transmission that we usually pay attention to when selecting a car. It is one of the configurations and is not universally representative.

  • Check the tire pressure after long-distance motorcycle riding

    As the only part of the motorcycle that is in contact with the ground, the tire is the key to ensuring the safety of the vehicle and driving. It is also the second focus of the vehicle inspection. After long-distance riding, we need to check the tire pressure and the top and sidewall of the tire to ensure that the tire pressure is maintained at the standard value, and the top and the sidewall are free from damage and foreign matter and the wear of the tire. If the degree of wear of the tire has reached the mark of the maximum loss of the tire, it is usually the mark on the sidewall or the projection in the groove of the placenta, which needs to be replaced if it reaches the mark.

    Because road tires without drains lose their ability to drain on slippery surfaces, the resulting drop in grip affects handling and safety. During or after the journey, the tread was found to be pierced by sharp foreign objects such as nails. For example, vacuum tires should not be removed immediately, so as not to accelerate the gas discharge. Note that the quickest and most troublesome thing to repair tires is to use tire repair strips, but it is easy to damage the tire cord during reaming and cause secondary damage to the tire. It is recommended to use it in an emergency.

    When the motorcycle reaches a certain mileage (generally 3000km-5000km), the dust in the air filter will accumulate to a certain amount, thus hindering the passage of air into the engine. At this time, the engine intake may be poor and the acceleration may be weak. In addition, due to insufficient intake air, the amount of oil in the mixed steam is too rich, resulting in an increase in engine carbon deposit and an increase in fuel consumption.

    All air filters should be checked frequently to replace the paper air filter or the cleaning sponge air filter in an emergency, so that the air filter is kept clean. Only the engine intake is smooth, in order to achieve the best working condition.

    Today, most small-displacement motorcycles are equipped with engine metal mesh oil filters to filter large particles of impurities in the oil, and medium- and large-displacement motorcycles are equipped with paper oil filters for higher filtration. .

    Clean oil filter can filter the metal particles or sludge in the oil to reduce the internal wear of the engine. When the motorcycle reaches a certain mileage (5000km), the oil filter element needs to be replaced to ensure the filter effect of the filter element on the oil. The cleaning of the metal mesh filter element is more convenient, and the removal and cleaning of the surface impurities can be removed.
