How to adjust the throttle cable after installing the carburetor on the motorcycle

There are grooves on the outer element of the throttle, and there are convex nails in the carburetor, which cannot be dropped. If the circlip falls off, you must match one, otherwise the main oil needle is easy to fall off. The circlip can also adjust the height of the main oil needle, which can save fuel.

I forgot to install the return spring, so the throttle valve can't return, and after installing it, it can be returned.

Next to the carburetor of the scooter, there is a semi-circular or disc-like thing, which is used to install the throttle cable, just clamp the end of the throttle cable in the hole in the disc, and just snap the throttle cable into the slot.

There are two throttle lines on the carburetor of motorcycles, both of which lead to the throttle handle on the right side of the handlebar, and the top one is the throttle line, which is responsible for controlling the throttle valve and the oil needle, that is, controlling the throttle. The one next to it is the accelerator pump line, when the throttle is screwed sharply, the carburetor can be sprayed with a stream of oil to the throat to improve the acceleration during rapid acceleration, this accelerator pump only works when the throttle is screwed sharply, and the normal driving is to tighten the throttle or the slower normal throttle is not working. Cars equipped with this kind of carburetor should be careful not to tighten the accelerator sharply when parking, otherwise gasoline will be injected into the cylinder and cause flooding, which will also waste gasoline.

There are adjustment screws at both ends, some are at one end, the outer wire is looser, and the gap is 3-5 mm.

The steps to install the motorcycle throttle cable are as follows:

1. Pass the throttle cable through the carburetor first.

Put the cover, then put the spring on the throttle line, and then extend the throttle cable through the throttle valve (the tube you said) hole, pull it out of the groove next to it and go around to the bottom, and release the head of the throttle cable into the Mekong groove at the bottom of the throttle valve.

2. When loading the throttle valve into the carburetor, pay attention to the small slope of the throttle valve.

Over there towards idling.

Screw, drop a long groove towards the side of the carburetor with a raised point in the carburetor, and then tighten the cap, and you can see the throttle valve falling to the bottom from the throat of the carburetor.

3. Open the lid of the plunger, and then pass the throttle wire through the middle of the spring of the plunger cover.

4. Pass the plunger hole of the throttle line, and then lock and fix it with screws to complete the installation.

Motorcycle carburetor.

The height of the oil needle of the throttle valve plunger is by adjusting the circlip on the oil needle.

Adjust the height of the oil needle by moving the circlip position. The adjustment of the height of the oil needle will affect the amount of combustible mixture provided to the engine, and then have an impact on the power, fuel consumption, etc., and because the oil needle is a cone, when adjusting its height, the impact on the oil supply of the carburetor is relatively large. Generally, a carburetor has only one suitable position for the height of the oil needle, and most of them have been adjusted and set at the factory, and there is no special situation that does not need to be adjusted.

If it is really necessary to make adjustments, it should also be carried out by repair personnel with professional maintenance experience, combined with the actual situation.

When the carburetor and motorcycle leave the factory, the circlip that adjusts the height of the oil needle is generally set in the middle grid, and the buried oil needle generally has five grids, that is, five adjustable positions, and the middle grid is suitable for most carburetors and motorcycles. If you change the position of the oil needle circlip without authorization and adjust the height of the oil needle, the low position of the oil needle may cause poor oil supply, insufficient throttle power, and the car will be cowardly. If the position of the oil needle is raised, it will cause the failure of excessive oil supply and excessive concentration of mixture, and will also cause failure to add throttle, insufficient power and large fuel consumption.

That is to say, the concentration of the mixture can only be just right, too concentrated or too thin is not possible, and there is only one suitable position for the height of the oil needle, and it is not possible to artificially change it high or low.

Only a small number of carburetors need to readjust the height of the oil needle due to the inaccurate factory setting, so remove the throttle valve plunger, remove the oil needle and its circlip, and adjust the position of the circlip in the oil needle groove. If you need to adjust, it is generally to move the circlip down by one grid, that is, to raise the height of the oil needle by one grid, but this requires screen experience and test drive, combined with the actual situation of the motorcycle to adjust. In addition, if it is a national three.

Emission of motorcycles, the carburetor oil needle can not adjust the height according to the regulations, but some carburetors for environmental protection standards, may be limited by the oil supply and caused by poor oil supply, so that you can add a thin copper pad under the oil needle circlip, so that the oil needle can also be raised a little higher, improve the situation that the throttle can not be added at a certain speed.

The oil needle of the motorcycle carburetor will also affect the mixing ratio to a certain extent, but generally can not adjust the fuel consumption through it, it can only be set to Tuqing in a suitable position, if artificially adjusted up or down, it may cause abnormal conditions. If the increase (refers to the adjustment is too high) will cause the mixture to be too thick and burn badly, and the low (too low) will cause the oil to be added, because the engine can not work normally, and will not achieve the purpose of fuel saving, so if it is adjusted in the case of normal vehicle conditions for more fuel efficiency, it is basically not able to achieve the purpose, and it will affect normal driving.

If the oil needle has not been moved, it is generally not its problem, and the oil lowering roller needle may cause the throttle to be added.

In addition to the black spark plug reducing the mixing ratio of the carburetor, other things such as blocked air filter, bad gasoline, aging spark plug or wrong calorific value, weak high pressure, frequent low-speed or short-distance driving, high oil level of the carburetor, improper use of the damper, aging of the carburetor or problems with the main measuring hole and main nozzle.

The main oil needle factory is in the middle of the grid, if the oil is big to put down then it will be a grid, small to mention a grid, this should be combined with the adjustment of the mixture, the idle speed is not good, the acceleration power will be abnormal, in a word, poor oil and rich oil are not the best state of Sunzhou dry mountain, if you have experience to adjust it carefully, if you don't know much about the carburetor to let the professional repairman deal with it, this is a small problem.

What I'm trying to say is how to install the throttle cable with the accelerator bar? It's mainly with an acceleration bar, and when you lift it a little, you can still say what he was like, and the line will be pulled to whatever position.

The replacement of the motorcycle throttle cable requires disassembling the carburetor plunger and throttle handle, and the specific operation steps are as follows:

1. Disassemble the seat screws for throttle installation.

3. Remove the pull cable.

4. Open the lid of the plunger.

5. Take out the plunger.

6. Replace the cable with a new one.

7. Install the upper head.

8. Tighten the handlebar.

9. Install the plunger.

10. Install the plunger back into the carburetor and it's done.

There are many different types of motorcycles, and although there are different ways to change the throttle cable, they are basically the same. To change the throttle line, remove the throttle handle sleeve and the carburetor cover respectively (vacuum membrane type does not use), compress the throttle valve and spring, remove the throttle cable from the throttle valve, and then pull out the old throttle line, and then replace the new throttle cable according to the original routing direction. The plunger of the carburetor has a direction, if it is a plunger carburetor, there is a long groove on it, and it should be aligned with a protruding pin in the carburetor when installing, or a ramp at the bottom of the throttle valve should be placed in the direction of the idle screw.

If it is a vacuum membrane carburetor, the installation direction can generally be judged according to the shape of the vacuum membrane and the top of the carburetor. After installing the throttle line, adjust the screws on the adjustment line, adjust the free stroke of the throttle to less than 5 mm, and then start the engine, turn the handlebar left and right, the throttle does not go up and down with the rotation of the handlebar, and finally check that the throttle cable is installed properly, and there is no danger of being scraped by other things.

The plunger has a direction to be right, otherwise it will be a flying car.

It is necessary to remove the upper cover of the carburetor, take out the return spring and throttle valve of the throttle valve, pass the throttle line through the groove and spring on the throttle valve, fix the solder joint of the head of the throttle line in the groove at the bottom of the throttle valve, and load the throttle valve into the carburetor according to the angle (pay attention to the positioning pin, otherwise the throttle valve will not fall to the bottom), and then install the upper cover of the carburetor.

Mu has a way to explain to you, the culture is low and the words are poor, so there is no way to describe it. The sound is particularly loud, indicating that you are stuck on the accelerator. The carburetor bucket was raised.

Find a motorcycle repair master to give you a little money. You can watch it from the side. That's how I learned.

If it fails, it is not installed, and the medicine looks like that kind of car, and there are many kinds of carburetors, and the throttle line is different.

Summary. Dear, I am glad to answer for you, the motorcycle throttle cord installation method is to pass the throttle cord through the upper cover of the carburetor, put the dan spring on the throttle line, and then pass the throttle cable through the throttle hole, and pull it out from the slot next to it to the bottom; Load the throttle valve into the carburetor; Open the plunger cover and pass the throttle through the middle of the plunger cover dan spring; Pass through the plunger hole of the throttle line and lock it with screws to complete the installation.

The method of installing the motorcycle throttle cord is to pass the throttle cord through the upper cover of the carburetor, put the dan spring on the throttle line, and then pass the throttle cord through the throttle hole, and pull it out from the groove next to it to the bottom; Load the throttle valve into the carburetor; Open the plunger cover and pass the throttle through the middle of the plunger cover dan spring; Pass through the plunger hole of the throttle pipeline, lock it with screws, and complete the installation.

Motorcycles are light and flexible, fast, widely used in patrols, passenger and cargo transportation, etc., motorcycles are divided into street cars, road racing motorcycles, off-road motorcycles, cruising vehicles, station wagons. A motorcycle is a nimble and fast tool with an internal combustion engine. The motorcycle was the world's first motorcycle invented by the German Daimler.

The installation method of the motorcycle throttle cable is: 1. Pass the oil world positive and scattered door line through the upper cover of the carburetor, put the spring on the throttle line, and then extend the throttle line from the throttle valve hole, pull it out from the groove next to it until it goes around to the bottom, and release the head of the throttle line into the groove at the bottom of the throttle valve; 2. When the throttle valve is installed in the carburetor, pay attention to the small bevel of the throttle valve facing the idle screw, and the long groove towards the raised point in the carburetor and fall to the bottom, and then tighten the cover. The two lines of the motorcycle are leading to the throttle handle on the right side of the handlebar, the top is the throttle search line, which is responsible for controlling the throttle valve and the oil needle, and the next to the clear seepage is the accelerator pump line, which can make the carburetor spray a stream of oil to the throat when the throttle is tightened sharply, so as to improve the acceleration during rapid acceleration.
