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.
1. It is recommended to check the high voltage assembly, electronic ignition, ignition coil, high voltage cap and spark plug. Aging of the above components can easily cause. failures.
2. Clean the main measuring hole and the additional measuring hole of the carburetor. If the main measuring hole and the additional measuring hole are not smooth, it may cause misfires.
3. The spark plug sleeve does not have enough current, resulting in insufficient electricity to burn the oil.
4. Check the air filter for dust.
5. There is a problem with the quality of the oil.
6. Release the clutch too quickly.
7. Shift too quickly.
Precautions for riding a motorcycle
1 When riding a motorcycle on a dirt road, the speed should be reduced. Since dirt roads are always uneven, high-speed driving will cause serious dents in the vehicle and shorten its service life. After long driving on dirt roads, the mounting bolts are easy to loosen. If you encounter a very rugged area, you can temporarily cut off the power and rely on the inertia of the vehicle to drive. At this time, the rider should support all his weight with his legs so that all the weight is transferred to the pedals and the body moves forward. Lean slightly and hold the handlebar firmly with both hands.
2. When you ride a motorcycle on a short, flat slope, it can roll down the slope at high speeds without having to slow down or shift into a lower gear. If you make a sharp turn after a climb or if theroad is unclear, you can climb the slope at high speed, slow down as you approach the top of the slope, and then continue driving after you can see the road clearly. When encountering long and steep slopes, high-speed running is permitted. If it is a variable speed motorcycle, you can shift to a lower gear depending on the engine power. Changes must be timely and movements must be agile. After shifting to a lower gear, you need to quickly increase the throttle and rush down the slope. When going downhill, if you find that there is a hilly slope in front of you, you can make full use of the inertia to roll down the slope while ensuring safety. When going downhill, if you have good visibility, you can shift into neutral and use inertia to descend to save fuel. When descending a steep slope, it is strictly prohibited to shift to panointed dead to avoid accidents caused by brake failure.
3. Try to avoid parking uphill, especially for motorcycles with stepped transmissions, which are more difficult to start uphill. After parking on a slope, disengage the clutch, brake the rear wheel with your right foot and land with your left foot to prevent the vehicle from rolling back. When starting on an incline, the clutch, accelerator and brake should cooperate well, increase the accelerator appropriately and gradually release the clutch. When you feel the driving force on the rear wheels, release the brakes and increase the throttle, and the vehicle will start smoothly. The main key to starting on a hill is when the brake is released too soon, the vehicle will roll backward; if the brake is released too late, the engine will stall. In short, the uphill start movement is relatively difficult and requires repeated practice and minuseful for achieving mastery.
4. When a motorcycle rides on a sandy road, because the sandy road surface is soft and the rolling resistance is large when the vehicle passes, the wheels will shake left and right and the handlebars will shake. be unstable. Therefore, it is necessary to slow down in advance and use both arms. Use force, hold the handlebars tightly, and do not use the emergency brake, especially do not use the front wheel brake to avoid sliding accidents.
5. Grooves often appear on dirt roads. When passing through shallow grooves, the vehicle must pass at an angle to the groove. If there is ice on the surface of the groove, the vehicle must pass vertically. , when you encounter a larger road crest, slow down first, refuel when the front wheels go up the road crest, and slow down lors the rear wheels cross the crest of the road.
6. When driving at night, the light is dim and visibility is poor. Driving speed should be lower than daytime driving and driving should be to the right of the center of the road. as much as possible. The distance between vehicles traveling at night should be increased, generally above 50 meters.
