The motorcycle can t be refueled, and the gas pedal exhaust pipe smokes and makes a sudden noise? 2

If it's a four-stroke machine:Burning engine oil emits blue smoke, but there is also a situation, that is, because the cylinder pressure of the machine cylinder is too low to start, in order to increase the cylinder sealing degree and improve the cylinder pressure in the gasoline tank added too much oil, in this case white smoke is often emitted.

If it's a two-stroke machine:White smoke from burning engine oil, and then there is damage to the crankshaft oil seal, so that the gear oil is sucked into the crankcase and added to the combustion, and a large amount of white smoke will also be emitted, accompanied by a smell of gear oil.

1. When the exhaust pipe emits blue smoke, first check whether the oil level is too high, because the oil level is too high and easy to cause the oil to go up. When checking the oil level, do not check the engine just after it stops, and check it again after 10 minutes of shutdown.

2. If the oil level is too high, the excess oil should be released in time. If the oil level is normal, for engines that have been used for a long time, check the possibility of increasing the gap due to the compression pressure of the cylinder and the wear of the piston, piston ring and cylinder, and the increase in the gap will cause the oil to go up.

3. If the above situation occurs, the piston ring should be cleaned or replaced. When the wear of the cylinder barrel is serious and the gap between the piston and the cylinder barrel exceeds the specified value, the cylinder is bored and the piston is replaced. For engines that have just undergone an overhaul or have had their piston rings replaced, it is common for the oil to be channeled due to the wrong filling of the inner and outer cuts (or chamfered corners) of the piston rings.

If this happens, the piston ring should be reinstalled.

4. Black smoke from the exhaust pipe to check the concentration of the mixture. After the symptoms of malfunction, first check the carburetor damper. When the engine is working normally, whether there is a phenomenon that the X longitudinal mechanism is stuck or malfunctioning and cannot be closed or opened, if so, it should be repaired or replaced.

The effect of installing an exhaust muffler on the exhaust pipe is as follows:

The motorcycle exhaust muffler can exhaust the exhaust gas when the engine is running, reduce the noise and temperature of the exhaust gas, and eliminate the flame and spark in the exhaust gas.

It can improve the exhaust efficiency, increase the engine power, if the carbon deposit is formed during the exhaust, the cross-sectional area of the exhaust gas channel will become smaller, causing the difficulty of exhausting, and the vehicle power will decrease, therefore, the carbon deposit in the exhaust muffler should be removed according to the regulations.

There are two types of motorcycle exhaust mufflers: box type and barrel type. The former has a good effect, but it is not easy to remove carbon deposits, and is more used in mopeds, such as Jialing CJ50 Yu moped and Xingfu XF50 Yu moped, etc., the latter not only has a good sound reduction effect, but also is easy to remove carbon deposits.

When the motorcycle is driving, there is a sudden failure, the throttle cannot be added, and the exhaust pipe emits black smoke, which is likely to be in the carburetor, and the main volume hole is loose.

Hello; There are a few points that you check one by one, 1Look at the timing right, 2See if the valve is leaking. 3.Clean the carburetor conditioning mixer.

The motorcycle throttle can't be added, and the exhaust pipe emits black smoke! What causes this situation?

Well, now that you can't get it, you just go and fix it, it's so annoying, you have to go to the store to buy the things you go, and you don't take the things. I feel like it's good to go back and fix it.

The mixture ratio is too strong! See if your filter is clogged?

There are many possible reasons for the failure of the motorcycle without adding the throttle, you can check whether the spark plug is bad, whether the high-voltage electricity is out of fire, whether the air filter and carburetor are blocked, and carefully clean the carburetor.

And check whether there are problems with the carburetor mixing ratio, oil needle, damper, etc., whether the gasoline is bad, whether the valve and intake pipe are leaking, etc., etc., these may cause this situation.

Precautions. 1. Don't go to the car wash shop or let others help wash the car, the car wash shop seems to have complete tools and operation specifications, but the problem of poor efficiency in its pursuit of efficiency also exists, and it will also make the cremation plug and various lines malfunction.

2. Be sure to cool down the hot car before washing. Suddenly washing the engine, exhaust pipe and other parts with cold water, the principle of thermal expansion and cold contraction is clear to everyone, which will destroy the oil seal of each part and cause oil leakage in the engine. It will also cause the chrome plating layer at the junction between the exhaust pipe and the engine to peel off and rust oxidized.

Dear, hello, when the motorcycle is small throttle, the exhaust pipe suddenly sounds, the related reasons are as follows?

The first vehicle spark plug gap is too large caused by this phenomenon, it is recommended to check the spark plug first, if the gap is too large, it needs to be replaced in time.

Second, if the carburetor is too dirty or the throttle is too dirty, it is recommended to clean the carburetor and throttle.

Third, if it is an EFI vehicle, it is recommended to clean the fuel injector and add some high-grade gasoline or fuel additives.

What is the reason for the sudden sound of the exhaust pipe when the motorcycle has a small throttle?

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, dear, the car master exclusive technician to serve you, attentive, careful, dedicated to the Xun Bureau of your car to answer your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this service helpful. If it helps you, we look forward to your likes and attention.

I wish you a happy New Year's Day, hello, when the motorcycle makes the car small throttle, the exhaust pipe suddenly sounds, and the relevant reasons are as follows? First, the spark plug gap of the vehicle is too large to cause this phenomenon, it is recommended to check the spark plug first, if the gap is too large, you need to replace the second, the vehicle carburetor is too dirty or the throttle is too dirty caused by this phenomenon, it is recommended to clean the carburetor and throttle Third, if it is an EFI vehicle, it is recommended to clean the fuel injector, add some high-grade gasoline or fuel additives.

EFI motorcycles only need to clean the fuel injector.

The EFI motorcycle is mainly to clean the throttle and idle motor, as well as the fuel injector.

Do EFI motorcycles have a gasoline filter?

If I have a gasoline filter, do I need to replace it?

If you want to use a gasoline filter, you need to replace it with a new one.

Does EFI motorcycle have a gasoline filter?

Most EFI motorcycles have a gasoline filter.

Where is the specific location of the gasoline filter, on the motorcycle.

And where is the idle motor?

The gasoline filter element is located next to the gas inlet of the vehicle on the connecting pipeline of the gasoline pipe and the high-speed motor is located next to the gas inlet of the vehicle.

As soon as the scooter throttle, the exhaust pipe will emit black or smoke, which is generally due toThe concentration of the mixture, the exhaust valve is not closed tightly, the ignition time is late, the gasoline oil quality is not good or the combustion is not sufficientcauses. Almost all of these causes involve multiple parts and multiple possibilities, so they need to be checked separately to find the specific cause of the failure, and then repair them as appropriate.

Check for over-concentration of the mixture due to various reasons.

Check whether the air cleaner is soaked in oil or blocked, whether the mixing ratio of the carburetor is too concentrated, whether the oil level and the height of the oil needle are too high, whether there is a problem with the electronically controlled damper and whether it is always in a thickened state, whether the main measuring hole and idle measuring hole are too large or fall off, whether there is a problem with the main nozzle, whether the carburetor itself is too poor or seriously aged, etc. Check whether the negative pressure fuel tank switch is damaged, it cannot be automatically closed after the ignition is turned off, or the gasoline seeping from the suction pipe of the negative pressure fuel tank switch causes the mixture to be too thick or flooded, etc., which will cause the mixture to be too thick, resulting in black smoke from the exhaust pipe of the scooter. In addition, check whether the quality of the gasoline is not good, whether there are other things mixed in the gasoline, etc.

Check if there are any problems with the valves, ignition time, high voltage, etc. Impulse

Check whether the valve clearance is too small, or the closure is not tight due to carbon deposits, wear, ablation, etc., especially the exhaust valve is not closed tightly, which will cause the fuel mixture that has not been fully burned to form black smoke. Check whether there is a problem with the ignition, magneto, etc., or the improper installation or fault of the camshaft, etc., resulting in the ignition time and late gas distribution, which will also lead to the failure of the motorcycle exhaust pipe with black smoke. Check whether there is a problem with the spark plug, high-voltage bag, igniter, magneto, etc., or whether the wiring between the electrical components of the ignition system is in poor contact, resulting in high-voltage weakness, which may also cause poor combustion and black smoke from the exhaust pipe.

The motorcycle throttle can't be added, and Zheng Zheng does black smoke with the balance pipe! What is the cause of this situation?

The motorcycle throttle cannot be added and there is a sudden sound, which is a symptom that the mixer is not easy to ignite when the car is cold, and only need to push the Japanese wrench at this time.

Turn on the Zephyr and it will return to normal, the specific operation steps are as follows:

1. Turn the car key to the right to turn on the power.

2. Press the one-button start button to start the vehicle.

3. Push the Japanese wrench to the left.

<>5. The motorcycle is running normally.

Precautions. 1. It is normal to open the cold car and open the wind.

2. The hot car should be turned off and windy.

The motorcycle throttle can't be added and there is a sudden sound, and the professional master will teach you to eliminate it.

Summary. There are the following reasons:

1. If the mixture is too thick, if it is a plunger carburetor (110cc engines are mostly ordinary plunger carburetors), screw the mixture screw to the end and then withdraw it for a circle and a half.

2. If the carburetor leaks oil, it may also be that the oil level of the float chamber is too high, and it will also cause the mixture to be too thick, so the carburetor should be disassembled and carefully cleaned and adjusted.

3. Check that the damper cannot be reset, and the mixture will be too thick such as black smoke and cannon when the hot car is driving.

4. Whether the air filter is blocked or soaked by gasoline and engine oil, and the air filter is not breathable, which will cause the mixture to be too thick.

Tip: Go to a repair shop to check the repair.

The sound of the motorcycle ignition has changed, and there is no exhaust and black smoke.

Hello; I am your automotive consultant, a special guest teacher, and the cumulative service has exceeded 10,000 people.

I've seen your problem, I'm sorting out the material for you, it will take a little time to type, please wait. 

There are the following reasons: 1.

Go to the repair shop to check the repairs.

Is there anything else you would like to consult? If not, please give me a thumbs up. You can also follow me. If you have anything to consult in the future, you can feel free to consult me. Have a great day, thank you.

The motorcycle does not catch fire, but there is a sound, the sound is not right, and the exhaust also emits black smoke.

Follow the preceding points to troubleshoot. Normal is caused by the above reasons.

The repairer said that there was a problem with the engine.

It is recommended that the above points need to be excluded. There will be no problems with a normal engine. If there is indeed a problem, it is caused by the clutch of the engine burning out.

Can that be fixed? Probably how much.

There is maintenance, ** normal is about 100 150.

Let's just ask a few questions about the above.

If you climb a hill, you won't feel very unmotivated?

If you feel very unmotivated, it is likely that the clutch is worn.

It's always been the first gear, the second gear throttle is also big, when I stepped on the neutral gear when I turned, I hit the accelerator, picked the second gear, and walked directly, and when I walked, I couldn't fire and emit black smoke.

That is most likely the clutch, and it is recommended to replace the clutch.
