Masters, and seniors, please help me answer the questions of novice scooters. 20

If you don't understand anything, don't buy it unless it feels very cheap The easiest thing is to open it and feel it yourself Listen to the sound is not rubbish The sound is very smooth Not rough is better When idling Use a towel to block the exhaust pipe for a few seconds Listen to the sound of the engine If there is an abnormal sound It is the kind of metal knocking sound or something Normal mechanical sound is fine But the sound can't be too loud Block it for a few seconds Otherwise it will turn off The above feeling is no problem Just set up a big brace Give the big throttle when idling Give it slowly See if the exhaust of the car is still pure and transparent at high rpm If there is obvious blue smoke, it means that the car is burning engine oil Basically it is almost impossible Add a little more to the price of scrap iron If you have to buy it If it is black smoke, the problem is not very serious It is very likely that there is too much carbon in the car This is okay It may also be a problem with the carburetor This is not very serious If the carburetor is not damaged, it can be adjusted Generally there are these colors of smoke Hehe If it is green, it is hell haha.

If the above inspections are fine, you should first ask the owner when was the last time you changed the oil, if he told you a few days ago, the problem may be more serious, twist the oil cap next to the exhaust pipe, and look at it, and wipe the oil dipstick with paper first.

The premise of twisting the oil cap is to support the big support, oh, hehe, and then put the oil cap on the cover, it is directly covered, do not twist it in, and then take it out to see the oil level on the oil dipstick If it is in the middle of the oil dipstick or above, it is no problem If you can't measure the oil, the car must be burning oil, or the engine is leaking.

If the owner deliberately conceals the truth, for example, the original car is slightly burned engine oil, and the exhaust does not have obvious blue smoke, you can't see it, and you can't see that he changed the engine oil before selling the car.

For the above situation, you can remove the cushion and ask to remove the spark plug If the owner says that it will not be removed, find a car repairer If not, give the master 5 yuan After removing it, look at the color of the spark plug Mainly look at the position below the middle electrode of the spark plug Note that it is the middle position Not the outer ring See if the color is brick red If it is brick red, it should be very good It means that the carburetor and engine are not bad If it is black, it may also be a problem with the carburetor or electronic damper This problem is not very serious It's more likely that the oil is burned slightly, that is, there is too much wear between the piston and the cylinder.

If the middle is black, the outer ring is also black Of course, the outer ring is generally black Unless it is a new spark plug See if the outer ring is wet If the outer ring is wet, it will be very dangerous Use a lighter to light it first If it is gasoline, it can be ignited If it is not lit and it is still wet, you can basically conclude that this car burns engine oil That is, it is going to be overhauled Change the cylinder or something The cylinder is not expensive Domestic cars are generally solved within 100 Look at the price of your side Hehe But it is more troublesome If you carefully read these I hit more than 3 times Basically, you can go and see the car, hehe.

It's too much fuel to catch up with the 125cc gear. I don't feel like I'm riding it, it's like a train. The pedal looks too meaty, so you don't need it.

See how the car is in good condition? Don't use those accessories, start and try it to see if the engine has any abnormal noise, good luck.

First of all, you must know that second-hand cars are the king of oil consumption.

To determine the performance of a used car, the most direct way is to listen to the engine sound after starting, idle speed, and then increase the throttle and so on.

Finally, it's about riding your bike uphill, downhill, highway, to feel it.

Let a connoisseur refer to you.

1. The scooter is continuously variable and has no gear, which is as good to ride as an electric car. Riding a scooter, turn on the key after sitting in the car, with the rear brake or front brake, and then press the electric start switch, release the brake and electric start switch in time after starting the engine, and then slowly increase the throttle with the right hand, and the car can start slowly. After starting, in the case of gradually adapting to the speed of the car, continue to slowly tighten the throttle to increase the speed, pay attention not to be too quick when twisting the throttle, otherwise the car may suddenly rush out.

2. When you want to slow down on the way to ride, you can close the throttle and cooperate with the brakes, novices can only use the rear brake, do not use the front brake, and then cooperate with the front and rear brakes according to the situation after being proficient. If you want to stop, you can first close the accelerator and cooperate with the brake to slow down, when driving to the parking position, completely release the accelerator, and use the brake to stop the car, and close the key to turn off, and then use the side bracket or main bracket to stop the car, press the key down to the end and then screw to the left, you can lock the handlebar, pull out the key and leave.

Pedal motorcycles are generally infinitely variable speed, give the throttle and go. There is no need for clutch gear, the handle that can be turned back and forth is the throttle, first open the key, start the motorcycle, and straighten the direction Look ahead with both eyes, gently turn the throttle back with your hand, and don't turn the throttle hard at first. The motorcycle slowly moved around and began to accelerate slowly, and the girl's words should be taught by someone who can ride.

The boy will practice slowly on his own.

What about scooter common fault repairs? Let's take a look at more detailed answers below! Common faults of scooters, maintenance of mixed gas is too thick, the car will have the following faults, the exhaust pipe emits black smoke, no idle start, and the fuel consumption increases, and the above faults are checked, and the negative pressure pipe is leaking, whether the carburetor oil float surface is too high, and there are debris pads on the oil float needle, resulting in the mixture entering the combustion chamber is too thick, and the combustion is not sufficient.

If the engine is overheated due to the difficulty of starting the cool car, the poor idle speed, and the above faults occur, it is recommended to check whether the valve clearance is too tight, and you can also check whether the spark plug is vulcanized to determine. The battery is not used for a long time, the fault is in the low-voltage coil power generation poor rectifier regulator burned out brake switch return bad anti-theft leakage, under normal circumstances when the engine is running at medium speed, the charging voltage of the motorcycle is between, the maximum does not exceed, the charging voltage is too high and too low is abnormal. In most cases, it is related to damage to the regulating rectifier.

The engine works normally, but the power output is insufficient, the starting is the car shaking, after excluding the first point above, focus on checking the wear of the Puli disc and the wear of the clutch of the pulley, and the starting jitter is related to the wear of the clutch of the pulley. The transmission belt is often broken, and the fault is directly replaced in the simple lead lead pulley.

According to your description, the scooter suddenly stalls when passing over a watery surface, and then needs to slow the throttle when it collapses and then ignites, and a little faster it doesn't start properly. This could be an issue related to the oil supply system.

Here are some of the possible reasons for the issue:

Ignition Problems Caused by Moisture: Water can penetrate the ignition system and cause ignition problems. You can check the ignition coils, spark plugs, and other ignition parts for moisture.

If moisture is available, dry them before reinstalling. At the same time, make sure that the ignition coil and wire are firmly connected.

Fuel supply problems: Water can seep into the fuel system, resulting in an unstable fuel supply. You can check if the fuel filter is clogged with water, and it is recommended to clean or replace the filter. Also, check that the fuel pump is working properly and make sure that there are no water leaks in the fuel lines.

Air Filter Issues: Although you mentioned that the air filter is not flooded, it is still advisable to check that the air filter is clean and not clogged. If the air filter is poorly vented, it may lead to unstable combustion.

If the above methods still do not solve the problem, it is recommended that you consult a professional technician or send the scooter to a professional repair shop for maintenance, they will be more familiar with the specific scooter model and possible causes of failure, and give more accurate diagnosis and solutions.

Here's mine, I hope it helps:

The problem of the scooter suddenly stalling after starting after passing over a watery road can be caused by a number of reasons. Here are a few possible reasons for your reference:

1.Engine moisture: Water may have entered the engine part of the scooter, causing the engine to become damp, which in turn affected the operation of the ignition system. Moisture in the engine can cause the ignition spark to be unstable, resulting in easy stalling at start.

2.Fuel supply problems: Water may enter the fuel supply system, affecting the normal supply of fuel. This results in an uneven mix of fuel, resulting in incomplete combustion at the start, resulting in stalling.

3.Moisture in the electrical part of the vehicle: Water may have entered the electrical system of the scooter and affected the operation of the electrical part. For example, it may affect the normal operation of ignition coils, spark plug wires and other components, resulting in unstable combustion and flameout.

4.Scooter construction problems: The structure of some scooters may not be waterproof enough, which can easily allow water to enter critical components, causing the start to stall.

In order to solve this problem, it is recommended that you follow these steps:

1.Park your pedal in a dry and ventilated place and try to evaporate the moisture.

2.Check the ignition system and fuel supply system of the scooter for moisture, and if so, clean and repair it in time.

3.Check the electrical parts of the vehicle for moisture and, if necessary, dry or repair.

4.If the problem persists, it is recommended to go to a professional car repair shop or workshop for inspection and repair.

Please note that the above are only some suggestions, and the specific reasons for Zheng Shu need to be examined in detail according to the actual situation. If you don't know much about vehicle repair, it is advisable to seek the help of a professional to ensure that the problem can be properly resolved.

It's not easy to work hard to code words, if my help to you, please be timely, thank you!

According to their own situation, first delineate a price range, carefully think about what the main bicycle to do (commuting or playing) and then choose the model, after the model is selected, look at the parameters, look at the workmanship, if there are conditions, it is best to test ride, you can find the shortcomings.

A scooter is a vehicle between a motorcycle and a car, and is a popular means of transportation. The inventor is Senior Engineer Corradino d'Ascanio. Sometimes people also transliterate it as Sukda.

The scooter is called "Wenche" in Taiwan, and correspondingly, "Wuche" refers to cruising cars, off-road vehicles, sports cars, etc., while Cantonese-speaking regions such as Hong Kong are accustomed to calling it sheep. Scooters are divided into many kinds according to their form and use: such as children's scooters, handicapped vehicles, gasoline scooters, folding scooters, golf carts, mini scooters, three-wheeled scooters, and so on.

A new car requires you to screw all the screws once! After that except for the security there is no more!

Watch your money! Don't fool the boss!

First of all, master the correct driving position. Of course, at the beginning, the posture is inevitably wrong, but if it is not corrected in time, it will form a quirk after a long time, and it will not be able to change it if you want to. The so-called driving skills are not an unfathomable technology, but a basic operation skill.

First, keep your body balanced. Because the body is not steady, it cannot be manipulated easily. Of course, it is also necessary to keep the motorcycle balanced and stable.

Second, even if the balance is stable, don't hold down the handlebars too hard. Because of the excessive force, it is difficult to easily maneuver without a look, and it cannot fully develop the inherent performance of the steering mechanism of the motorcycle. Third, it allows the body to move freely.

That is, you can change the posture of the body according to the needs of the operation, or add weight to the pedals or saddle. Or change the posture to reduce the weight of the pedals and saddle to achieve the balance of the car body in different states.

The left and right feet step on the ground at the same time, grab the left handlebar with the left hand, grasp the brake handle with five fingers at the same time, grasp the right handlebar with the right hand, and press the start brake button with the thumb of the right hand at the same time, when you hear the motor start, let go of the brake, slowly refuel with your right hand, and put your feet on the pedal. When the motorcycle has been started, it is necessary to control the direction of the car, pay more attention to the surrounding environment while driving, if you are a novice, the speed is not too fast, everything is safety-oriented. In normal times, we should pay more attention to the maintenance of motorcycles, and frequent oil and air cleaners are very important in the daily maintenance of scooters.

About 2000 kilometers to change the air filter, 1500 kilometers to change the first oil. In addition, the gas state of the tire is also very important, and it is necessary to always insist on whether the tire is out of air in order to replenish it in time. When driving on the road, you should also choose a flat road, if it is potholes and poor road conditions, it will increase the fuel consumption of the motorcycle and will also cause harm to the car.

The scooter has no gear, moving, generally the left hand brake for the rear brake, the right hand for the front brake, a small part of the pedal rear brake to use the foot, other buttons are no different from other motorcycles, when riding, sit on the point, both feet low, the left foot retracts the bracket and press the start button to ignite the motorcycle, light throttle, the car will slowly go forward, then you can raise your feet, try to master the balance, proper throttle, feel completely balanced after putting away your feet on the pedal, you can set off.
