How to operate the idle speed of the motorcycle, where to adjust the idle speed of the motorcycle

To put it simply, the idle speed can be adjusted by adjusting the size of the throttle opening. Open the left side panel of the motorcycle, and twist the idle speed adjustment screw clockwise to adjust the idle speed to increase the idle speed, otherwise, adjust it to a smaller one; Generally speaking, the lowest stable speed at which the engine does not shake or stall is the best idle speed.

In terms of operation, the correct way is to take the method of "one high and one low" to adjust the idle speed. The so-called "one high" means that when adjusting the mixture adjustment screw, we should try our best to increase the speed of the engine (the purpose is to make the oil and gas ratio of the idle oil supply system the best); The "one low" means that when adjusting the throttle screw, the engine speed should be reduced as much as possible (the purpose is to make the opening of the throttle smaller, so as to reduce the fuel supply to the oil supply system).

The specific adjustment method is as follows:

The first step is to prepare. When the throttle knob is completely relaxed, there should be a certain free clearance, the air filter should be installed, and the other components should be confirmed to be in good condition and the oil meets the standard. Then, start the engine to warm it up and open the choke door completely;

The second step is presetting. Adjust the throttle screw to ensure that when the throttle knob is completely relaxed, the engine can run at a certain speed without stalling;

The third step, one high. Adjust the air adjustment screws to increase the engine speed as much as possible;

Step 4, a low. Adjust the throttle screws to reduce the engine speed as much as possible (125 displacement 1400r m; 100 displacement 1500r m). The adjustment parameters of the mixture are not mechanical, even if it is the same model of the same batch, there will be differences, and the mixture screws of this car are screwed in and diluted and withdrawn in and concentrated.

As long as the engine runs smoothly, starts smoothly, accelerates smoothly, and the fuel consumption is normal, in addition, the color of the spark plug can be used to help judge whether the concentration of the mixture is appropriate, under normal conditions, the color of the spark plug should be brown, too black or too white is not normal, but the most common is too black. You can ride like this for a few days to observe, and if there is nothing abnormal, you can use it like this without adverse effects. The gas mixture screws of the scooter are generally screwed to the bottom and exit two turns.

However, the performance of mopeds varies greatly and needs to be adjusted according to the actual situation, and the same is true for other motorcycles.

Summary. First start the engine to warm up, and when the engine temperature rises to normal, adjust the idle screw, the idle screw is on the right side of the body, and it is best to remove a shield shield in front of the seat cushion, you can see it. Before the screw is flushed, there is a spring under the screw, and the tightening is to increase the idle speed, and loosen it to lower the idle speed.

The normal idle speed should reach 1600 rpm, and the idle speed of EFI motorcycles is slightly higher than that of other types of vehicles. If there is no tachometer, you can feel that the engine runs smoothly and continuously without interruption, and if the start is a little uncomfortable, turn it up slightly.

The idle speed of the motorcycle is adjusted in **.

The idle position of the motorcycle is on the carburetor, and there is an idle adjustment screw. Start the motorcycle first, let it warm up to normal temperature, and then rotate the idle screw with a flat-blade screwdriver to adjust. If the speed is high, slowly adjust it in the counterclockwise direction, and if the speed is low, it will be adjusted along the clock, and it is normal to adjust it to about 1500 rpm.

Well. 1.The first step is to prepare for the return of Chang.

Start the motorcycle. Take a screwdriver and find the location of the ** mark. 2.

The second step is presetting. Adjust the throttle screws so that the engine can run at a certain speed without stalling. 3.

The third step, one high. Adjust the air adjustment screws to increase the engine speed as much as possible. 4.

Step 4, a low. Adjust the throttle screws to reduce the engine speed as much as possible.

This kind of thing. <>

First start the engine to warm up, and when the engine temperature rises to normal, adjust the idle screw, the idle screw is on the right side of the body, and it is best to remove a shield shield in front of the seat cushion, you can see it. The screw is rushed forward, and there is a Weitang collapsed spring under the screw, and the tightening is to increase the idle speed, and loosen it to adjust the low idle speed. Normal idle finger circle speed should reach 1600 rpm, EFI motorcycle idle speed is slightly higher than other types of cars.

If there is no tachometer, you can feel that the engine runs smoothly and continuously without interruption, and if the start is a little uncomfortable, turn it up slightly. Right.

1. Check whether the air filter is installed, whether the other parts of the vehicle are in good condition, and whether the oil meets the standards. After the inspection, start the engine, warm up the vehicle, and open the choke completely.

2. Adjust the throttle screw to the point that the lever is not screwed, which can also keep the engine running and not turn off.

3. Adjust the air screws to increase the engine speed, adjust the throttle screws, reduce the engine speed, adjust the 100 displacement car to about 1500 rpm, 125 displacement car to about 1400 rpm.

Precautions for riding motorcycles:

1. Riding a motorcycle should also be listed, and have relevant documents, carry documents, now the traffic law is very strict, the traffic police will not only check the car, but also the motorcycle.

2. Try not to take the fast lane, the fast lane of high-speed vehicles will make you difficult to control.

3. Don't overload, the general motorcycle only carries two people, carries too many people, the weight is too large, it is easy to control, and it will be caught by the traffic police.

4. Driving a motorcycle is also to observe the rearview mirror, never look back to observe, and get used to the rearview mirror.

As shown in the figure below, the middle of the carburetor is the idle screw, clockwise screwing is to increase the idle speed, counterclockwise screwing is to lower the idle speed, the idle speed should be adjusted when the car is hot, the idle speed after the hot car can be at 1500 rpm, the idle speed is low or no idle speed when the car is cold, it is relatively normal to pull the damper to start and preheat it for a while.

MotorcyclesIdlingThe adjustment method is: useScrewdriversTurn the idle screw.

If the idle speed is too low, use a Phillips screwdriver clockwise.

Turn the idle screw. If the coil is vertical and the screw is at the bottom, if you look from above, you need to turn the screw counterclockwise. Turn the screw 1-2 times for fine tuning, or 3-5 times to significantly increase the idle rpm.

It should be noted that adjusting the idle speed requires the motorcycle to be started, which is convenient for judging whether the idle speed is appropriate. In addition, located carburetor.

The rest of the adjustment bolts on the machine can not be moved, such as the mixing ratio adjustment bolts, etc., incorrect adjustment will lead to insufficient power of the vehicle, guns and other failures.

What is Motorcycle Idling?

Idle speed refers to the speed of the engine when the engine is not active output, depending on the type of car and the amount of chaos and have different values, the so-called engine idle is when the throttle valve is almost fully closed, the engine is in neutral.

The lowest speed in the case, in layman's terms: idle speed is the working speed of the engine when the vehicle is parked and waiting!

Many friends who have bought a new car, when they buy a car, they can see that the merchant unpacks the car and packs it, and then starts it, and then uses a small change cone.

Adjust a small screw on the carburetor, and that's adjusting your car's idle speed!

After your patient running-in, after a few months or even 1 year of riding, you will find that the idle speed has changed a little bit from the beginning, which is the phenomenon of poor idling, which is mainly manifested in the three phenomena of engine rental without idling, idle too high, and unstable idling.

How to adjust the idle speed:

1. Rotate the mixing ratio screw in the positive and negative directions (here we are not confined to screwing to the low and then reversing the circle), until the engine speed is the highest, stop the rotation of the shirt, if you are not at ease, you can rotate a few more times until you are satisfied.

2. Rotate the idle screw counterclockwise to keep the idle speed as low as possible, and the ignition shall prevail.

3. Repeat the steps and adjust patiently, so that you can get a satisfactory idle speed by repeating it repeatedly.

After the idle speed is adjusted, ride for a long distance, under normal circumstances, the color of the insulating porcelain in the center of the spark plug should be brick red.

Open the seat cushion, and then there is a cover under the seat cushion, and when you open the cover, you can see the carburetor. There is a screw in the carburetor, which is made larger clockwise and smaller counterclockwise.

Tune in to the sound of "energetic and upright", there is no such lifeless, large and small idle unstable situation.

The rear wheels rotate slightly, but the rotation speed is very slow, with a slight resistance, and the yard stops.

After 4 to 5 minutes of hot cars, it is still guaranteed not to turn off.

Idling too low is not a good thing, it hurts motivation a lot. Especially in urban driving, the idle speed is too low but it costs fuel, and every time the electric starts, the car hurts the battery and the fuel consumption once.

The carburetor has two zigzag screws, one is to adjust the air intake and the other is to adjust the oil output, first screw the air needle screw to the end, and return it for 2 turns. The oil adjustment needle makes the idle speed appropriate. Then the left and right air control needles make the engine idle speed the highest (no gas pedal), and then adjust the oil needle to reduce the oil supply, so that the idle speed is appropriate, if you are not satisfied, you will do it again, it will definitely be OK.

The reason is: the most suitable air intake can make the idle speed the highest, and the oil needle can be lowered to save fuel.

It must be adjusted in the case of a hot car.

1.After starting the car, warm it up for 3-5 minutes;

2.Full reset choke;

3.Screw the idle speed adjustment limit screw to the engine speed of 1500 rpm - 2000 rpm per minute (if the car does not have a tachometer, it can be judged by feeling, slightly higher than the normal idle speed);

4.Slowly screw the mixture screws in or out left and right until the engine revs at its highest speed. The smoothest operation;

5.Adjust the idle screw so that the speed is 1000 rpm-1300 rpm. Or the idle range you want.
