1. Check the spark plug
When you encounter this situation, the first thing to check is the spark plug. There is a spark plug sleeve in the vehicle tool. spark plug and insert it into the high voltage connector. On the cap, attach the metal part to the cylinder block to test for fire. If there is no fire, you can replace a spark plug and try again.
2. The motorcycle cannot start after reversing and waiting for tens of seconds.
It is inevitable to crash while riding a bicycle, but many people try their best to lift the motorcycle after a crash and find that it cannot start. Typically, this situation occurs in cars equipped with carburetors. Reversing will cause fuel to leak into the carburetor. You just have to wait tens of seconds for the gasoline to flow again into the float chamber of thecarburetor. and the fuel system can work normally.
3. Check the high pressure packaging and the high pressure cap.
If you replace the spark plug with a new one, or remove it from another normally operating motorcycle and install it on the defective vehicle for testing, and there is no still no fire, you need to check if the high-voltage cap is loose. With vehicle vibration, the high voltage cap will loosen easily and the high voltage cap should be tightened before starting the test.
4. Clean the nozzles of each pipeline of the carburetor
When we accelerate suddenly when the car is hot and idling, especially the vacuum carburetor (CV type), it will cause mixture If the air is too thin, it will turn off automatically. At this point it is necessary to clean the nozzles of each carburetor pipe,then accelerate smoothly and gently after starting, try to avoid rapid acceleration and avoid artificial transition faults. If the motor burns out while accelerating at high speed, the main influencing factor is that the high voltage and current formed during high speed acceleration make the high voltage flameout protection in the stabilizer rectifier of voltage comes into effect and the motor turns off.
5. Repair the electrical system
Except for running out of fuel, most faults caused by sudden stalling while driving are caused by the electrical system. The emergency kill switch is defective and may cause a circuit break and stall. Defective ignition coil. If the ignition coil connector becomes loose and misfires, check each connector and remove oil stains to ensure stable contact. Defective trigger coil. LThe trigger coil wire connector is loose and misfiring. Plugging it back in and trying to strengthen the connector can solve the problem urgently.
High speed misfires are primarily related to ignition system components. The high voltage assembly (including the high voltage cap) and the igniter should be mainly checked. In case of failure, the magneto stator coil. and the wiring between them should also be checked, if the mixture is too rich, the air filter is clogged or the spark plug electrode gap is incorrect, the car may not be able to apply the accelerator, but it will not cut off. the fire. You can also maintain, clean and debug the carburetor.
