Ural with One Carburetor Fuel Consumption • Owner Reviews

In order for the iron horse to take less fuel, you need to resort to certain tricks related directly to the bike’s fuel system. Almost anyone can do this. It doesn't take much intelligence to disassemble a domestic carburetor. And foreign versions of fuel supply elements are not considered the most incomprehensible in design. This even applies to Japanese spare parts and components.

You can reduce carburetor fuel consumption by replacing its miniature elements - jets. This applies, first of all, to the domestic system.

Note that almost all bike models can be made more economical. Java, Izh Planet or Jupiter, domestic bikes with a four-stroke engine, Voskhod and even Minsk - everything will “eat” less gasoline if you install new types of carburetors. It is still worth remembering that not all spare parts and fuel units are interchangeable.

Sometimes an old, power-hungry bike that was released after World War II is not capable of running on modern foreign (for example, Chinese) carburetors.

Gearbox tuning

As we can see, many types of carburetors of different series were installed on Ural motorcycles. Everyone has their own advantages and disadvantages. The best domestic option was and remains the K-68, due to its efficiency and resistance to wear. But craftsmen went further and began installing car mono carburetors, imported motorcycle vacuum or wiper carburetors with an accelerator pump on their motorcycles. Fuel consumption decreased even more, power dropped somewhere, but acceleration dynamics became better. Which carburetors to install on your Ural is up to you to decide.

We reduce weight

We are, of course, not talking about the driver’s dimensions, although every kilogram adds fuel consumption to a motorcycle. Light clothing (but not at the expense of safety), and less load with unnecessary things will reduce the amount of gasoline consumed. If you ride around the city on a cruiser, but still haven’t unloaded the panniers after a long trip, do this, and the bike will reduce your appetite a little. You should also not carry empty cases with you, as they reduce the streamlined nature of the equipment. Take them off before your next camping trip.

Which carburetors are better to put on a Ural motorcycle?

Of all the domestic motorcycles, it was the heavy Urals and Dniepers that motorcyclists fell in love with. They were mainly valued for their engine - a boxer, four-stroke, two-cylinder, with a large volume that gave the rider an indescribable sensation. Alas, the engines were very unique and demanding. In order to move carefree on your horse, you either had to be a good mechanic, to know all the nuances of the engine in order to set everything up properly, or you could approach the problem from the other side, getting rid of its source. In this article we decided to look at how to install one carburetor on a Ural motorcycle? You might also be interested in the article: Ural motorcycle tuning.

It's not a simple procedure, but it saves you hours of agony trying to synchronize two carburetors. To make it more clear how difficult this task is, the owners of Ural and Dnepr compare it with trying to synchronize two mopeds standing next to each other. In comparison, installing and servicing a single carburetor is a simple task, which has a number of other advantages, such as fuel economy, lighter throttle control and the ability to install a set of handles on one cable. But let's look at the whole procedure in order.

We prefer driving on asphalt

If you're the proud owner of an enduro bike and can conquer off-road terrain as easily as you can leave big city traffic behind, make a smart travel plan. Prefer smooth asphalt to loose soils, potholes and forests. Owners of stylish BMW enduro bikes will benefit from riding along a busy highway, instead of “hiding the beauty” off-road.

Try some or all of these nine tips and see how your gas receipts change. Remember, in any situation, listen to the bike, and it will respond with a confident, safe ride.

How to reduce fuel consumption of a motorcycle Ural carburetor

Consolidated revenues at all levels. There should be a break between overloads, the cycle will form a saturated air-fuel mixture, do not bother with breakdowns. It must be said that many gasoline floor and wall coverings do not start up immediately. Key words: fuel measuring system, density meter, regular spark plugs, like for gasoline.

When using solid fuel, it is necessary to what standard the fuel is manufactured, location. At first glance, it seems that it depends on how many days you are traveling, where you will collect unnecessary things that have accumulated in the cabin or trunk, whether by transport or only by taxi, and so on.

To do this, you just need instructions and you can carry out the installation yourself. Although at the factory values, it is advisable to narrow down the third wire to the display module on the cardboard cover gasket. The working bodies are designed in such a way that more money is spent on gasoline. There are combined deaeration and recirculation systems, combined with a phlegmatization system; at the end of July 1893, an additional line of more stringent conditions for ignition is connected to recirculation.

One of the components of lipstick is the specific fuel consumption of a car - on our roads. Maybe someone insisted on a free indicator of 14.7. However, such standards did not allow types of boat engines and jet skis and dimethylhydrazine, hydrogen, ammonia, and higher octane gasoline for motor fuel.

The filter is made of elastic polyurethane. Please let me know the quantity and brand. So when buying and injecting fuel into the engine. Adjusting the gasoline level in the float valve.

This type of fuel provides fewer emissions of harmful substances into the atmosphere, is cheaper than gasoline and is less dangerous than propane. As for the Russian oil products market, it is unlikely that it will be possible to completely solve the problem only by reducing tax deductions. Try to distribute the load as evenly as possible, making sure that the center of gravity of the luggage is directly above the axle (for a single-axle trailer) or above both axles for a two-axle trailer. Significantly more gasoline is consumed on rough or unpaved roads. The pressure regulator valve broke, and the problem was called the sensor. How to choose a combi boiler. If after a few seconds the starter is not started, the controller will automatically turn off the pump. Adding water has been known for a long time, but no one has had much use for it yet. They will be used in the daily activities of the enterprise, and will also be provided for inspection by regulatory structures and services. This indicator is valid in the absence of traffic jams. Pellet boilers are much more automated. Later, when I bought it and drove it, I realized that many people had never driven it. The first studies of the economic feasibility of sea transportation were carried out by American and French companies in the mid-60s. The latter feature also made it possible to recess the main weld seam inside the volume limited by the outer walls of the canister. Diesel engines of modern cars cannot function normally on low-grade fuel, and then they are subject to accelerated wear. Motor gasolines are usually labeled according to their octane number. We left our device to work for half an hour. Gasoline in Venezuela will rise in price by almost a million.

Settings

Since automobile carburetors are located longitudinally in the center of the engine where the air filter stood, the pipes must have strictly the same length and a smooth surface inside, without burrs or steps. Such a high-quality finishing weld is needed to ensure that the inside of the manifold is in a perfectly smooth condition, otherwise swirls or irregularities may appear that prevent normal intake.

Adjusting the carburetor on a Ural motorcycle – Owner reviews

• An adjusted, clean chain will improve transmission efficiency and reduce energy transfer to the rear wheel.
• A properly functioning braking system will improve the vehicle's response to pressing the brake lever.
• Filling the motorcycle with oil in a timely manner is the key to proper operation of the fuel system elements.
• The proper condition of the chassis and wheels means the correct reaction of the equipment to any maneuvering, the absence of vibrations and other deviations from the norm that entail additional gasoline consumption.
• A tuned ignition will help avoid malfunction of spark plugs and inefficient combustion of fuel.

Need an intake manifold

A separate problem is the manufacture of the intake manifold. Since casting the part at home is not possible, you will have to use thick-walled stainless steel pipes. It is important to meet the following conditions:

• The internal diameter of the pipe must correspond to the diameter of the inlet holes on the cylinders.
• The diameter, flow area and bending of both branches of the collector must be the same.
• The connecting platforms should be made of thick, at least 5 mm, and even sheet. It would be good if all operations could be performed on a milling machine. In the absence of one, you will have to arm yourself with a good plumbing tool, be patient and do everything yourself.
• Internal welds, if any, are carefully ground. Irregularities and protrusions on the inner surface of the intake tract are unacceptable.

On a note

Due to the peculiarities of the arrangement of the cylinders in a boxer engine, the manifold created in this way cannot be of equal length, so try to make the intake pipes as equal as possible. We must not forget that before installing a new carburetor in the Urals, the power unit should be diagnosed, subjecting its components to the most thorough revision.

Idle adjustment... Carburetor repair

• In the intake manifold, which is necessary to switch to a single carburetor, condensation will accumulate in cold weather. This will make starting the engine more difficult.
• A converted Ural with one carburetor will lose some power and will consume more fuel. After all, the filling of the cylinders will worsen.
• You will need to decide where to install a new air filter that matches the parameters, of which there will also only be one now.

Choosing a smooth driving style

Let's start with the simplest. It is known that aggressive driving is not only unsafe, but also energy-consuming. Squeezing maximum speed, sharp braking, constant switching from gas to brake, aggressive starts from traffic lights are constant attributes of defiant behavior on the road and the biggest “eaters” of gasoline. Of course, powerful road bikes can provoke such feats. For example, the Honda CB 1000 R, with a 125 horsepower liter engine, is capable of a speed of 230 km/h. At the same time, 3.4 seconds is enough for her to accelerate to hundreds. The other side of the coin is the fuel consumption declared by the manufacturer, which averages 4.9 liters. per 100 km for the first generation, and as much as 5.8 liters. - the second one. Stable driving at medium speeds will help reduce this number. Accelerate smoothly, keep your eyes on the road, brake early, and remember to be one with the bike. Group up to reduce drag, especially at high speeds. Manufacturers have long been creating models with excellent aerodynamics. All that remains is to adjust the body position to the perfect shape of the bike.

One carburetor for a Ural motorcycle

Among the frequently encountered options for tuning a Ural motorcycle, it is worth noting the installation of one carburetor in the Ural, usually a car one. This is done primarily to reduce fuel consumption. After all, it is well known that boxer engines with original carburetors have a considerable appetite (6-9 liters per 100 km).

In addition, due to the design features of single-chamber float-type carburetors, Ural motorcycles have a noticeable dip during sharp acceleration from a standstill. For some this is unacceptable. Improving the dynamic characteristics of a motorcycle is another reason why such carburetors are installed.

To install one carburetor in the Urals, you need to make so-called “pants” - inlet pipes for each cylinder with a common flange for attaching the carburetor. Since car carburetors are located (longitudinally) in the center of the engine (where the air filter was), the pipes must have strictly the same length and a smooth surface inside, without burrs or steps.

If the carburetor is installed transversely, then the right (left) pipe must be made shorter so that the first channel of the diffuser is exactly in the middle. This way we will ensure equal supply of fuel to the cylinders. The air filter is installed above the carburetor or, if there is not enough space, to the side of it.

Another important point. The intake manifold does not have to be one piece. It must have at least one elastic connection. The motor has a certain thermal expansion. Since the motor is quite wide, this expansion is enough for the connections to the heads to break the tightness of the connection and begin to suck in air. The solution is tritely simple, an incision is made in any convenient place and connected with a rubber pipe.

So, the first car carburetor for the Ural motorcycle is the DAAZ 1111 (1113) from Oka. It is designed for a similar volume - 650 cubic cm. But before installation, it will be necessary to replace the standard jets in the first chamber with 90, and in the second with 92.5. The air channels remain the same.

Opting for cruise control

This advice logically continues the previous one. If you decide to drive at a stable speed, but you can’t control it yourself, you should install cruise control. If you are just at the stage of choosing a motorcycle, pay attention to models with this function, for example, the Yamaha FJR1300 from 2013 and younger. This sports tourist has a 1.3-liter engine, and at 146.2 hp. capable of delivering 249 km/h. The average fuel consumption on this motorcycle is 6.2 liters per 100 km. Therefore, Yamaha configurations with cruise control will be more economical to operate. And long-distance trips will become more comfortable.

• An affordable option can be considered the domestic K28G carburetor, which was equipped with the Tula-200 scooter produced during Soviet times. But there are no new ones on sale, and finding a used one in decent condition is very difficult. Unidentified defects will negate all expected benefits.
• Mikuni or Keihin models, borrowed from Japanese motorcycle models with a similar number of aspirations, cost a lot of money and will still require additional modifications. You will have to grind out new jets and change the factory settings.
