The carburetor synchronizer allows you to stabilize the power system of a motorcycle or other equipment. The need to use such devices is due to the fact that over time, any system begins to function asynchronously. This causes increased detonation, leading to accelerated wear of the power unit. The device for leveling the power supply can be made independently. Consider the stages of manufacturing the unit, its capabilities, as well as the correct adjustment and testing of carburetors.

Signs of asynchrony

The use of a carburetor synchronizer may be required in the following cases:

• There is an increase in fuel consumption.
• Idle setting is off.
• Excessive vibration is felt when the engine is running.
• Black smoke coming out of the exhaust pipe or shooting sounds.

If after cleaning the carburetor the indicated manifestations do not disappear, synchronization of the individual elements of the assembly will be required. You can perform this procedure yourself. It is enough to know the order and some subtleties of the manipulations.

Synchronizer carburetorshands

First, you will have to purchase the necessary materials and fixtures. Among them:

• Manometer or its vacuum equivalent. You will need as many appliances as the carburetors will be processed (usually 4 pieces).
• Fuel lines. They can be replaced with a regular dropper. Selection by quantity is done in the same way as with measuring instruments.
• Wooden block measuring 400150 millimeters.

Then it remains to attach the measuring instruments to the bar, connect the hoses using special fittings, the carburetor synchronizer is ready.

Next, the device is calibrated. All hoses from pressure gauges are connected to a source of discharged air, after which the readings of the instruments are compared with each other. If there are discrepancies in the readings, twist the arrow of the corresponding pressure gauge in the right direction. Now you can proceed directly to the synchronization of the unit.

Toolkit

To set up several carburetors operating in the same fuel system, it will be necessary to carry out certain preparatory work. To carry out the manipulation, the following devices will be required:

• Directly carburetor synchronizer.
• Set of screwdrivers and wrenches.
• Rag.
• Gloves.
• Fuel tank equipped with a fuel outlet.

This simple set is available to every user. Then you can proceed to the mainworking.

Sync

After preparing and cleaning the carburetor, the synchronization process itself begins directly. It is carried out in several steps. Since the work consists in setting the same values \u200b\u200bof the discharge of the air mixture at idle, you will have to adjust the throttle valves of each element. In this regard, open access to them will be required. To do this, remove all parts of the motorcycle that make it difficult to access the required elements.

Then the fuel tank is dismantled. Instead, a substitute is placed with special taps, to which the carburetor synchronizer will be connected. If there is an air filter, it is also desirable to remove it. This will improve the efficiency of the upcoming procedure.

Main Stage

This stage is the most responsible. Each fuel hose that is available in the motorcycle carburetor synchronizer design is connected to special channels. The main thing is that the connection is airtight and connected to the necessary channels intended for synchronization.

Plugs are found and dismantled on the carburetor body. Connect the synchronizer and start the power unit. After the engine has warmed up, it is adjusted for minimal fluctuations at idle. You can find these indications in the instructions from the manufacturer of the serviced equipment. Pay attention to the pressure gauges. If they are identical, nothing else is possibledo. Otherwise, adjust the position of the arrow to the desired parameter using special screws designed to adjust the throttle.

Important points

You already know how to make a DIY motorcycle carburetor synchronizer. When setting up, there are certain things to keep in mind. First, the process is carried out between a pair of adjacent elements, and then between the other two parts. That is, if there are only two carburetors, only one screw will have to be adjusted to the desired position. If there are four elements, first adjust one screw between adjacent elements, and then another one to synchronize the pairs with each other. Further settings are made in the same way.

As a result of the procedure, the readings of all measuring devices should be equal. Then synchronization can be considered successful.

Features

When creating a do-it-yourself carburetor synchronizer, you need to take into account a number of points when assembling and setting it up. First, you must first prepare the fittings. They are taken at the rate of 2 pieces per checked element. The tubes are aligned and sawn into pieces, then they are threaded. The length of these parts does not play a special role, as long as they do not interfere with the work process.

Secondly, you will need to cut the prepared hose, after trying it on. The length of this part should be moderate so that it does not cling to parts of the power unit. The resulting tubes are cutin half, putting one end on the pressure gauges. Before this, it is advisable to rewind the fittings of measuring devices with a sealant (twine or fum tape). Plastic taps are connected to the second edge, also sealed along the thread. In the case of using dropper systems, you don’t even need to cut anything. Standard clamps act as faucets.

To finally make the synchronizer of motorcycle carburetors, it remains to attach the pressure gauges to the wooden case.

In closing

Time to take stock. A carburetor synchronizer can be bought at a store for 4-5 thousand rubles. Such a device is equipped with a set of fittings for different configurations. The device will pay for itself in just a couple of checks, if we compare this procedure at a service station. However, it is much more profitable to make a do-it-yourself carburetor synchronizer. Having spent a small amount, you will get a very accurate device with a long working life. Savings compared to the factory version will be at least 50 percent. At the same time, the manufacture of the device will take no more than an hour, and its efficiency is comparable to factory counterparts.
