The wrong way to maintain a motorcycle

Motorcycle maintenance methods are basically the same as cars, but many seemingly correct maintenance methods are actually wrong. Let’s take a car as an example to see if there are any mistakes in your daily maintenance of your car.

1. Wash the car under the scorching sun-hurt the paint

Many private car owners like to wash their cars under the scorching sun, believing that the water on the car body can be dried soon after washing. In fact, it is wrong. When washing the car under the scorching sun, the convex lens effect formed by the water droplets will cause the uppermost layer of the car paint to produce a local high temperature phenomenon. Over time, the car paint will lose its luster. If waxing at this time, it is also easy to cause uneven color of the car body. Therefore, it is best to wash and wax the car under sheltered conditions. If it is not guaranteed, it is best to choose it in the morning and evening when it is cloudy or sunny.

2. Too much oil-malfunction

When the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will be poorly lubricated due to the small amount of oil, aggravating the degree of wear, and even causing a bush-burning shaft accident. However, if there is too much oil, the crankshaft handle and the big end of the connecting rod will be violently agitated when the engine is working, which not only increases the internal power loss of the engine, but also increases the oil splashing on the cylinder wall and causes the oil burning failure. . Therefore, the oil in the engine oil pan should be controlled between the upper and lower engraved lines on the oil dipstick.

3. The bolt is too tight-permanent deformation

There are many fasteners connected with bolts and nuts on automobiles, and it should be ensured that they have sufficient pre-tightening force, but they should not be over-tightened. If the screw is overtightened, on the one hand, the connecting piece will be permanently deformed under the action of external force; on the other hand, the bolt will be stretched and permanently deformed, and the pre-tightening force will decrease, and even cause the phenomenon of sliding buckle or breaking.

4. The new battery does not charge-shorten the lifespan

The first charge of the battery is called the first charge, and the first charge has a great influence on the service life of the battery. If it is not charged, that is, if it is used directly with "water", the capacity of the battery is not high and its life will be shortened; if it is directly charged, it will also shorten its life. Generally, the initial charging of the battery is after filling the electrolyte, and then it can be installed and used after charging with a small current for about 1 hour.

5. Random addition of equipment on the car-affects driving safety

It is understandable that car owners pursue comfort and luxury, but some car owners install various equipment in the car by themselves. If this modification is not handled properly, it will often adversely affect the performance and the convenience and reliability of the car, and it is easy to leave sequelae. Or affect driving safety.

6. The cooling water temperature is too low-wear the engine

In the hot summer weather, in order to prevent the temperature of the water-cooled engine from being too high, the cooling water temperature is required to be as low as possible; some drivers simply remove the thermostat in order to achieve the purpose of cooling. These practices are wrong.

Water-cooled engines are both afraid of heat and cold. If the cooling water temperature is too low, it will worsen fuel combustion, increase fuel consumption, aggravate wear, increase oil viscosity, and reduce engine power. Tests show that when the cooling water temperature is 40-50 degrees Celsius when the car is running, engine wear will increase by 60%-80%, power will be reduced by 25%, and fuel consumption will increase by 8%-10%. Therefore, the temperature of the engine cooling water is not as low as possible. Generally, it should be controlled between 80-90 degrees Celsius.

7. Long-term non-use of the car or short-distance use of the car-damage to the machine parts

Some people are usually "reluctant" to drive, and only drive out to play during holidays. In fact, this way of using a car is very harmful to the car. The surface of transmission parts such as engines and gearboxes will rust because they are often in direct contact with the air, and batteries will also affect their service life due to long-term natural discharge. The best way is to run the car every few days for 30 to 40 minutes. In addition, always using the car for short distances can also hurt the car. The car is moving at any time but can't drive far, which is an important reason for the injury.
