  • Some rubber parts of motorcycle may corrode and age

    The oil will not be oxidized for a long time. It can be observed through the oil observation port to see if it has changed color. Generally, it is not necessary to change the oil again. In addition, the oil of the piston, cylinder head, cylinder and valve train has been slowly left to the bottom. It has not been lubricated for a long time, and the resistance is relatively large. It is not good enough to stabilize the idle speed. When starting for the first time, you can use the foot start lever to step a few times. Let the oil moisturize and then start the motorcycle.

    There is a cleaning agent for cleaning the motorcycleburetor. You can remove the spark plug, spray it from the hole of the spark plug, and reinstall the spark plug. Because it is easier to ignite than gasoline, it is easy to ignite. motorcycle start will be very helpful.

    After the motorcycle has been put on for a long time, some rubber parts may corrode and age. In particular, some joints are hardened, causing the engine to leak out of the cylinder and causing the inability to catch the motorcycle. At this time, these small parts need to be replaced.

    There are also some special cases. The motorcycle has not been used for a long time. Some rats ran in and broke the wires, or the joints in the connection area were oxidized, which was a fatal problem. Especially for the EFI motorcycle, there was no sensor line. Exclusion makes it impossible to get on the bus, and it is not very easy to find. At this time, it is necessary to motorcycleefully check whether the ignition and fuel supply signals are normal.

    Motorcycles can't catch fire, don't blindly beat the motorcycle, must rule out the reasons to solve the re-test, if blindly repeated taxis, it is easy for a lot of gasoline to run into the tank, wet the spark plug, causing the so-called "drown tank" phenomenon, this time let You think that the motorcycle is broken and you can't figure it out. Actually, remove the spark plug and wipe it off with a dry cloth.

  • The carburetor of motorcycle needs to be cleaned

    If it is an EFI motorcycle, it is often that the battery has not been charged for a long time, and the battery is seriously depleted. The lead plate is aging and decomposed. The electrolyte inside is evaporated and dried. It usually starts once a month and runs for about 10 minutes to charge. If the battery is broken, you can try adding some water. If you can't replace it, you will obviously hear the starter is weak.

    The motorcycleburetor motorcycle will also be unable to start due to battery depletion, and the treatment method is the same as that of the EFI motorcycle. In addition, the motorcycleburetor motorcycle, there will always be residual gasoline inside the motorcycleburetor. These gasoline and air will be in contact for a long time, and impurities will run in and oxidize into colloid. These gels will block the main orifice and the idling orifice. At this time, the motorcycleburetor needs to be cleaned before it can be started.

    Because the gasoline is degraded, even if the motorcycleburetor does not have the problem of blocking the hole, it is necessary to discharge the gasoline inside through the oil drain hole below, let the oil in the tank re-inflow into the motorcycleburetor, and then start the motorcycle. Although the EFI motorcycle has little oil left in the nozzle, if the parking time is too long, it will not be ruled out that the gel will block the nozzle. At this time, the nozzle needs to be removed for cleaning.

    The fuel tank to the motorcycleburetor or the line between the nozzles may also be clogged. It can be removed and blown with the mouth to ensure smooth use.

  • Regular oil changes and machine filter of motorcycle

    Motorcycle maintenance In addition to changing the oil and air filter, these points are also very important!

    The first point: machine filtration.

    Regular oil changes and machine filters are things that everyone knows, because motorcycles can easily reach high speeds, so there are many more maintenance time than cars, and they have been at high speeds. More, so the machine can also be cleaned together.

    The second point: air filter.

    The replacement of the air filter has been affected by the environment. The replacement time has not been determined. If the city is riding, it can be maintained at about 10,000 km. If it is in a place with a lot of wind and sand, the cycle will be shortened because it is empty. The filter is basically paper paste, but do not wash it with water when cleaning. Use air pump to blow off the soil.

    The third point: steam filtration.

    Steam filter is a gasoline filter. This has a big relationship with the quality of gasoline. If the quality of the gasoline you add is not very good, the fuel filter will play a role in filtering the impurities, but if it is so long, the impurity product Less time, it will be time to clean up.

    Fourth point: brake pads.

    The brake pads are very useful. As long as the brakes are used for riding, and the brake pads are also related to the safety of the vehicle, the brake pads must be very importantly maintained. Lao Wang recommends replacing them at around 30,000 kilometers. Or maintenance.


  • Motorcycle has the performance of resistance to the left and right vibrations

    The lower body is supported by the seat and foot pedals, while the upper body of the forward leaning is supported by the lower body. In order not to cause the upper body to fall forward, it is necessary to use the strength of the back muscles, that is, the lower abdomen is recovered, the waist is relaxed, and the back is "arched". This posture not only makes the upper body smooth, but also maintains the softness of the body. The elbow is in a semi-curved state.

    Only in this way can the wrist maintain a relaxed "free" state for softness and freedom. The lower jaw is lifted slightly, but it is never extended forward, otherwise it will force the wrist and shoulders, and affect the freedom of manipulation. Whether you are going straight or turning, don't consciously twist your body to "force" the motorcycle. This not only affects the meticulous manipulation, but also increases your fatigue.

    The more he is a motorcycle master, the easier his posture is, and he does not feel tired when driving for a long time or at a high speed. The reason is that the whole body is relaxed. Of course, it is not right to be motorcycleeless. The key is to relax in time. Because the motorcycle itself has the performance of resistance to the left and right vibrations, of course, this is also the role of your lower body, which is the "double knee clamping" effect repeatedly emphasized. In the long-term practice, people have summarized the importance of “clamping both knees” and repeatedly emphasized this issue in the driver training class. In addition to the knees, the inner side of the thigh can be placed against the fuel tank and attached to the side cover with the calf.
