What is the reason why the motorcycle vomits and can t be refueled?

There are many possible reasons why the motorcycle can't add the throttle, and you can check the air cleaner separately.

Whether the carburetor is blocked, clean the air filter and carburetor, and check whether there is a problem with the mixing ratio, oil level, oil needle, damper, etc. of the carburetor, whether the quality of the carburetor itself is relatively poor, whether the gasoline oil quality is not good, and the spark plug.

Whether it is bad, high voltage.

Whether there is a fire failure, whether there is air leakage in the intake pipe and other hoses, and whether the ignition time is wrong, these are all common reasons why the country cannot add the throttle.

The main reasons why motorcycles can't refuel are as follows: clogged carburetor, improper mixing ratio, too small valve clearance, and lack of oil. 1. Carburetor blockage:

If the idle gauge hole is blocked, it is manifested as no idle speed; If the main quantity hole is blocked, it is manifested as poor refueling at high speed, which is the so-called lack of refueling. In this case, remove the carburetor and clean it to recover. 2. Improper mixing ratio:

When the mixing ratio is not right, the car will idle.

The motorcycle is difficult to start, the climbing ability is poor, the speed response is slow when the throttle is suddenly increased, and it is difficult to reach the maximum speed within the specified time or can not reach the maximum speed at all. The main causes affecting the acceleration performance of motorcycles are oil circuit reasons and high-pressure ignition.

Circuit. Cause. Mechanical reasons, human causes, etc.

First, the reason for the oil circuit.

1.Oil. The dilution of the mixture causes the gas to act on the piston after the ignition outbreak is insufficient, and the combustion time is prolonged, and the engine overheats and other failures.

It is judged that the cause of poor oil is poor acceleration during operation, and when the damper or pump oil is toggled by hand, the acceleration improves. When the thickened mixture is not used, there is a weakness of acceleration, and then we can. Say that the motorcycle is in a poor state of oil.

There are many reasons for poor oil, which can be mainly divided into the following points: (1) Carburetor reason: main oil needle withering:

Low; The oil level adjustment is too low; The main measuring hole is partially blocked; The carburetor interface is loose and leaking; The air filter is not installed; The fuel switch of the fuel tank is not well supplied with oil.

2) Poor sealing of the crankcase of the two-stroke engine: the oil seal of the crankshaft on one side of the generator fails and leaks; Air leakage on the seam joint surface of the crankcase; The joint surface of the crankcase and the cylinder leaks or the piston assembly direction is wrong (not assembled according to the mark, mainly referring to the two-stroke car).

3) Cause of the flute valve of the two-stroke engine: the flute valve is damaged; The rotary valve is reversed, causing the carburetor to backspray.

2. Oil-rich. The mixture is too thick and causes the motorcycle to increase at low speed.

Most of the cases are due to oil circuit problems, check if there is something buried in the carburetor, or if there is water or air in your oil.

There are many reasons that may lead to the motorcycle not being able to add the throttle, check whether the air filter, carburetor and exhaust pipe are blocked, clean or replace the air filter, clean the carburetor, and check whether there is a problem with the mixing ratio, oil level, oil needle, damper, etc. of the carburetor, whether the spark plug is bad, whether the high-voltage electricity is out of fire, whether the gasoline is not good, whether the gas distribution timing is wrong, whether the cylinder pressure is insufficient, whether the valve and intake pipe have air leakage faults, etc., which will cause the throttle to be unable to be added.

1. Failure of oil supply system.

At this stage, most of the motorcycle fuel supply system is carburetor, so we must first find the problem from the carburetor. Before finding a carburetor fault, you must make sure that the fuel is 100% devoid of water and that the air filter is not clogged.

2. Circuit failure.

Circuit faults can be solved by replacing spark plugs, igniters, and high-voltage packs.

3. Mechanical failure.

Mechanical failures, such as excessive valve clearance, wrong valve distribution time, etc.

Through the above inspection and maintenance faults can be eliminated, but when inspecting and maintaining, we must carefully observe the symptoms of the vehicle, which will allow you to take a lot of detours.

The reasons why the motorcycle throttle cannot be added are: 1. It may be that the mixture is thin or the oil cannot be added due to the lack of preheating after starting; 2. It may be a problem with the engine; 3. The carburetor is blocked or the mixed gas adjustment is unreasonable, the oil level in the carburetor float chamber is low, the valve clearance is too tight, and the spark plug is slightly broken and scattered.

The carburetor has some air intakes. It may be clogged inside.

The motorcycle can't be refueled when it's cold, and it can be solved without spending a penny, have you learned?

When the motorcycle increases the throttle and spit out, you can check whether the air filter and carburetor are blocked, clean the carburetor, and check whether there are problems with the mixing ratio, oil level, oil needle, damper, etc., whether the spark plug and gasoline are bad, and whether the high-voltage electricity has a high-speed fire failure.

Motorcycles can't add up to the big throttle, and this failure involves a variety of possibilities, including the engine itself, the intake and exhaust, and the carburetor.

There are many aspects such as fuel supply system, ignition system, gasoline oil quality, etc., and each aspect may have a variety of reasons, so it can only be investigated separately for these aspects, first find the specific cause of the failure, and then debug, repair or replace the problematic parts.

If the motorcycle can't add the throttle, the first thing you should check is the air filter.

Check the air filter and carburetor and exhaust pipe for blockage.

Whether it is soaked in oil or blocked and cannot be ventilated, clean or replace the air filter, clean the carburetor, and check whether there is a problem with the mixing ratio of the carburetor, the oil level, the oil needle, the damper, etc., the concentration of the mixture can only be just right, too thick or too thin may cause the throttle to be unable to be added. Check whether there is a problem with the damper or if it is not used properly, but if it is just that the cold car can't add the throttle when it just starts, but the throttle can be refueled normally after the hot car, then there is no problem, and the damper can be pulled when the car is cold.

Check whether the gasoline in the fuel tank can flow normally, whether the fuel tank switch and gasoline filter and oil pipe are blocked, and whether the gasoline oil quality is not good. Check the spark plugs.

and high-voltage electricity for high-voltage lines.

If the high-voltage electricity is abnormal, check whether there is a problem with the spark plug, high-voltage bag, igniter, magneto, ignition switch, electric door lock, flame-out switch, etc., and whether the line between them is faulty. Check whether the valve timing is wrong, whether the cylinder pressure is insufficient, whether there is any air leakage in the valve and intake pipe, valve arm and camshaft.

Whether there is insufficient intake and exhaust air due to wear, etc., these may cause the oil to be infilled.

Summary. When the ignition energy is not enough, the spark plug is lost, or the ignition coil voltage is low, and the mixture cannot be ignited, this situation will also occur, you can replace the gasoline filter and spark plug and then try again, or the same problem, clean the carburetor or check the gasoline pump, and the ignition coil. Due to the high speed of the motorcycle, the compression ratio of the engine is also larger, and the gasoline of the national standard must be used, otherwise the fuel label is not enough to cause deflagration at high speed, which will affect the power output of the engine and greatly shorten the service life of the engine.

The motorcycle can't afford to refuel, and after 4,000 turns, it vomits and is powerless.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

When the ignition energy is not enough, the spark plug is lost, or the ignition coil voltage is low, and the mixture cannot be ignited, this situation will also occur, you can replace the gasoline filter and spark plug and then try again, or the same problem, clean the carburetor or check the gasoline pump, and the ignition coil. Due to the high speed of the motorcycle, the compression ratio of the engine is also larger, and the gasoline of the national standard must be used, otherwise the fuel label is not enough to cause deflagration at high speed, which will affect the power output of the engine and greatly shorten the service life of the engine.

The fault of the motorcycle is not oiled, which is divided into not on gasoline and not on the engine oil, and the lack of gasoline is the problem of the fuel supply systemThere are mainly gasoline pumps, fuel tank switches, oil pipes, gasoline filters, carburetors or throttle injectorsand other issues; without oil,The main reason is that there is too little oil in the engine, or the oil pump is damaged, and the oil filter, filter or oil passage is blockedcaused. It is necessary to repair according to the specific fault and situation.

If the motorcycle is not supplied with gasoline, check whether there is no gasoline in the fuel tank or too little gasoline, if there is too little gasoline, it will also lead to poor fuel supply or the fuel tank can not produce oil. Check whether the vent of the fuel tank cover or the one-way valve between the fuel tank vent pipe and the carbon tank is blocked, which will cause a vacuum to form in the fuel tank and affect the normal oil output of the fuel tank. Check whether the fuel tank switch is used correctly, whether it is in the closed state, and pull the fuel tank switch to the auxiliary tank position when the oil is low.

Check the fuel tank switch and gasoline filter and oil pipe for blockage, carburetor for blockage, clean the carburetor, and checkWhether the nozzle hole of the carburetor is blocked, whether there is a problem with the mixing ratio, oil level, oil needle, damper, etc., whether the cylinder pressure is too low, whether there is air leakage in the intake pipe and other hoses related to the engine, carburetor, negative pressure fuel tank switch, secondary air supply system, etcThese may also cause non-oiling.

If there is no oil in the engine, check whether the oil in the engine is gone or too littleWhether the oil pump is damaged and the pressure is insufficient, whether the oil filter element, oil filter screen and oil channel are congested or blocked, and whether the oil channel is leakingOil ducts are found in the engine case, cylinder block and cylinder head, as well as crankshaft and some transmission shafts, if they are blocked by foreign objects such as impurities, it will also cause the engine to not get oil, resulting in wear and damage to engine parts, and in serious cases, it may also cause the engine to lose its maintenance value and be scrapped.

There are several reasons why the motorcycle oil can't be refilled: 1. > the throttle line is stretched straight; 2> The throttle valve in the fuel tank is blocked; 3> Maybe the tank is out of gas at all.

The motorcycle can't afford to refuel, and it's hard to start; It's usually dirty here, you know? We just need to open the carburetor and see that there are two screw holes, and we can just clean the inside and solve the problem.

See if the grease nipple or filter is clogged.

Summary. Consultation Record · In this case, the throttle is normal on the spot, and it is boring to run, so you need to check whether the spark plug is caused by a problem, remove the spark plug and take a look, if the gap is too large or blackened, replace the spark plug directly.

Ride at low speed and vomit.

At. In this case, check the spark plug first.

Is the teacher normal?

This spark plug is useless.

I don't think there's any gap at all from **.

This spark plug needs to be replaced.
