Under normal temperature conditions (-5 °C or above), when the motorcycle engine fails to start normally after 2-3 starts, it indicates that there is a fault, and its fault is nothing more than the three major elements of circuit, oil circuit and cylinder pressure. As long as the oil circuit is unblocked, the circuit is normal, and there is a certain pressure when the cylinder is compressed, the engine can start and work normally. Under normal circumstances, because no pressure cylinder failure (mainly crankcase, cylinder leakage, piston ring wear and breakage caused, check cylinder compression is good spark plug hole, if they feel there is a violent impact, "pop" is heard, fingers Being pushed open, that is, the compression is good. Otherwise, it is necessary to "hospitalized"), and the engine can not be started very rarely. A large number of faults occur in the circuit system, followed by the oil circuit. Therefore, as long as we master this principle And try the following methods, under normal circumstances, you can quickly start the motorcycle.
1, can not start after a few days of parking
The knights have some experience. When the love 驹 is parked for a few days, it is quite difficult to start. The engine is breathing and breathing for a while and then rests still. How can it not start? Experienced people naturally try to start the engine in a cart-starting manner . This method seems easy, but there is still a little trick.
First of all, to determine whether the reason can not be started is the circuit problem or other problems, it is not difficult to distinguish, twist the car key to the [ON] position, check the speaker and headlights, if the speaker does not ring, the headlights are not bright, indicating the battery The power is running out. This is because the battery capacity of the motorcycle is small, and the battery is insufficient due to continuous self-discharge after parking for a period of time. This is not a big deal. As long as the motorcycle is started, the battery will be sufficient when driving for a certain distance. Of course, if the battery has been dead, it still can't be charged normally after it is started, it should be replaced as soon as possible. In general, in addition to the continuously variable pedal cars, motorcycles other by way of the cart can be started quickly starting the engine, the specific method is as follows:
First, do a few warm-up exercises to stretch the bones, avoid excessive force and strain the muscles; then push the motorcycle out of the parking position, ready to push at a distance of at least 10m straight ahead; then check the fuel supply system, fuel tank is there after sufficient fuel? gasoline whether the shape is set in an open position? ready to work, to straddle the motorcycle, the transmission gear attached two (generally 2 or 3 block most easily startup speed), when the engine is not rotating but linked The 2nd gear may be a bit of a hassle, as long as the motorcycle is shaken a few times before and after, it can be easily entered. After entering the second speed, when the clutch is engaged, and then straining the rock several longitudinal motorcycle, the motorcycle full use of its own weight of the piston ring and the cylinder wall lubricate, reduce starting resistance, while the crankshaft is avoided The top dead center or bottom dead center position that is difficult to start helps the car to start when the cart starts. Then, get off the car and lean on the left side of the car. Hold the two hands in the direction of the grip, keep the 2nd gear, pull the choke door up a bit, twist the car key to the [ON] position, hold the clutch lever at the same time with your left hand , disengage the clutch , slow. Slowly push the car forward. When the car reaches the highest possible speed, release the clutch and turn the throttle, then the engine will start. At the same time, immediately disengage the clutch and keep the throttle, and the right index finger and middle finger operate the front brake to brake the front wheel to stop the car. The right foot will hang the transmission in the neutral position, put down the parking bracket, let the car idle for 2-3min, you can start. If you are skilled, push the car forward 5m to start the engine .
2. The motorcycle cannot be started after the car is overturned.
It is inevitable that the motorcycle will be accidentally rolled over. After several hard work, the engine can't be restarted. In fact , the fuel in the carburetor is leaking. Just wait for 10 minutes and let the car re-flow into the carburetor float chamber. The oil supply system can work normally. However, the leaked fuel may accumulate in the intake manifold. If the engine is forced to start, the spark plug will be soaked and unable to ignite, and the engine will not start naturally. At this point, you will smell a strong smell of gasoline. You should drive the throttle to the maximum within 10 minutes of waiting, let the carburetor butterfly valve open as much as possible, so that too much gasoline will evaporate and the engine will be normal. Started.
