Higher, further, stronger, or Briefly about tuning
Snowmobile ?Buran? ? one of the most common snowmobile models in our country. In terms of power, it is comparable to a small tractor capable of transporting small loads. It will not be possible to make a racing snowmobile out of it, but some modifications are still possible.
By replacing or customizing standard parts, you can achieve greater productivity, efficiency and ease of use of this model. ?Buran? begins to obey its owner more if the moment of starting is sharpened, the maximum speed is increased and the centrifugal regulator is adjusted. In addition, you can make your snowmobile consume less fuel, which will help you save a lot of money. You can read about some of these upgrades and do-it-yourself tuning below.
Engine modernization and tuning
To adjust the draft force of the motor, it is necessary to adjust the crankcase by milling its channels. It is important to sharpen and clean all irregularities and roughness. Thanks to this, the Buran engine will be able to work much more productively, which will allow its power to be restored to its required level? 36 l. With. Other upgrades aimed at increasing the power of the snowmobile are also possible. You can replace a standard carburetor, for example with a Mikuni. In addition, the engine will produce more power if you use good gasoline, for example, 92nd.
Craftsmen also strive to increase the number of engine revolutions. The basic Alpina installed on a snowmobile is somewhat limited, so if you have some experience, it can be slightly tweaked to work the way we need. The easiest way is to replace the standard regulator with a more advanced one, for example, “Safari?” ? the model that is installed on the “Taiga” and ?Lynx?. Many foreign snowmobiles are equipped with regulators of a similar design. At the same time, we did not feel any significant difference when installing them.
?Safari? easy and cheap to tune and configure. Thanks to the modernization of ?Buran? Does this regulator achieve good results? The speed of the snowmobile increases and fuel consumption is significantly reduced. How is this possible? The fact is that the standard “Alpina” It’s just not refined properly, hence the increase in power.
We improve cooling and sound insulation
To improve your snowmobile's cooling, it is important to maintain carburetor, ignition, and lubrication settings. But the problem is radically solved by refining the cooling system. To do this, you need to properly insulate the exhaust system. In this case, the air will not be heated by the exhaust manifold. On the other hand, due to high temperatures, muffler segments may burn out. Therefore, it is more correct to organize a separate air supply and install a heat shield separating the cylinders from the exhaust manifold.
The effectiveness of this approach will be immediately noticeable, even if you do not have special sensors installed. Some use a double fan for cooling. However, this is not a completely proven method, since, according to the theory, both impellers can interfere with each other.
Many users also complain about the ?volume? ?Burana?. To make it quieter with your own hands, you can replace the roller bearings with others of a closed type. This will prevent you from having to change the lubricant as often, which will result in a quieter overall operation of the snowmobile. In addition, it is possible to insulate the Buran engine compartment using inexpensive modern materials.
Complete modernization of the snowmobile
To completely modernize a snowmobile, some companies provide special tuning kits. It is worth noting that by purchasing parts this way, you can sometimes save a little. Here is a typical kit for upgrading a Buran:
- two-cylinder engine with a power of 22 hp. With. from Honda;
- modern four-cam Arctic regulator;
- battery with an energy reserve of 24 A/h;
- bumper bumper;
- engine mounting cable;
- new hood with sound insulation.
You can make your ride more enjoyable by improving your snowmobile's braking system. A standard lever is not suitable for this purpose, since braking is given to the driver at the cost of incredible effort. To facilitate the process, a lightweight spring is installed, and the lever arm is increased.
External tuning
To make driving a snowmobile convenient, you need to purchase and install a modern on-board computer. The functionality of such a device is quite wide? it can display on special indicators the speed of “Buran”, the number of engine revolutions, its temperature, conditional mileage and a convenient clock. This will not only expand the capabilities of the model, but also make it more modern.
To make your sled more attractive, you can update the hood, install LED bulbs, upgrade the night lighting and add a bumper bumper at the front. The latter looks stylish and will protect the Buran. from collisions and impacts.
The updated, reupholstered seat and body paint will add sportiness to the snowmobile. A stylish and at the same time useful feature will be the presence of a winch, which is selected in accordance with the pulling capacity of the model. The installation of a wide off-road track will add aggressiveness, which, among other things, increases the snowmobile’s ability to pass through snow drifts and makes it more maneuverable.
As you can see, the good old “Buran”, with successful tuning and proper modernization, in some respects can give a head start to imported snowmobiles. Externally, as can be seen in the photographs, after proper tuning, it looks especially impressive.
Shock absorber for Burana ski
The shock absorber is specially designed for the Buran snowmobile and constant operation in a horizontal position, which will ensure its correct and trouble-free operation in the most severe conditions.
The shock absorber improves handling and ride comfort, including in reverse, eliminating ski lifting. When driving on hard surfaces, it eliminates the rumble and noise of ski impacts. The shock absorber differs from a car shock absorber in its filling and is designed to operate down to -50°C in ice and snow conditions.
Is it possible to make a Buran snowmobile with two skis?
The experience of many do-it-yourselfers says that it is possible. Moreover, there are “Buran” snowmobiles with two skis, which perform many useful jobs - servicing electrical networks in the northern regions, in rescue services, in the ambulance service. There are also many of them in the garages of hunting and fishing enthusiasts.
The main idea of everyone who wants a Buran with 2 skis instead of one is a smaller turning radius and greater stability. This is a significant advantage when driving on difficult terrain. In addition, there is such a thing as “planing” in the snow. It is felt while driving on freshly fallen, powdery snow, which has great depth. Usually these are snowdrifts in the forest. A snowmobile with two skis moves forward well on such a road if you know how to control it and maintain speed, but with one ski it often “sinks.”
Typically, remodeling takes a long time and requires special knowledge, tools and parts. But converting the Buran snowmobile into two skis will not always improve its performance. For example, many argue that with one ski he can get through the bushes much better. Considering that the banks of most reservoirs have not been mowed for a long time and are thickets of willow bushes, willow bushes, willows and other similar plants, this quality may be useful.
Is it possible to make a Buran snowmobile with two skis for driving through the forest? Some argue that with one “Buran” ski it is better to pass through dense forest. For example, if you catch a tree trunk between your skis, there is a high probability of breaking them, but with one ski you can usually pass such an obstacle if you hit your mask.
Again, slowing down when driving in the forest can lead to burying in the snow. Hunters who do a lot of riding in the trees and don't have much snowmobile experience might want to consider whether they need this kind of modification.
Engine block RMZ-640
An RMZ-640 engine block assembled from original parts with already installed races with cuffs (high-quality, equipped with a ring to prevent the spring from flying off), a modernized DD exhaust manifold with improved exhaust manifold gaskets, original spark plugs from Japan, will allow you to quickly, efficiently and on a budget make repairs or upgrading your Buran snowmobile.
You can also equip the engine with a modernized cooling system, an electric starter, ignition, a manual starter, high-voltage wires and spark plug caps, an original K-65Zh or Mikuni carburetor, throttle and corrector cables, a built-in or free-standing fuel pump, a bushing for a variator or an electric starter crown at your discretion.
Since 2015, the crankshaft can be equipped with a high-quality roller bearing on the variator side, which significantly increases the service life of this unit by reducing the load.
Clips with crankshaft seals for RMZ-640
Everyone knows of cases when standard oil seals are squeezed out during operation and the engine fails. Also, the cause of engine failure is the destruction of the spring, after which its contact with the edge of the cuff also disables this unit. Damage to the seals leads to a lean mixture as a result of air leaks and is a consequence of the destruction of needle bearings and burnout of the pistons. The idea of a new design of the races and additional modifications to the crankshaft was proposed by V.P. Novoseltsev.
We have just finalized this unit, eliminating the shortcomings of the design developed during times of shortage, when it was necessary to use oil seals designed for auto-box shafts.
To ensure long-term engine service, instead of the standard ones, races with an imported cuff are used, manufactured according to aviation standards and withstanding high engine speeds and increased pressure.
Operation over several years has shown the reliability of the design and trouble-free operation of the engine.
What parts are needed?
For the remodel you will definitely need:
| Steering mechanism | You can use any automotive mechanism with a steering column and rods. The standard mechanism for one ski or another from motorcycle equipment will not work |
| Additional springs for skis | The easiest way is to use spring springs. You can take them both from a car and from various mechanisms. It is necessary that the springs be able to be adjusted and attached to the ski, and also have the same stiffness. The springs must provide the ski with a certain degree of freedom so that it can swing back and forth a little. |
| Two skis | They take shorter ones than the one for the single-ski circuit. They also need to have a curve at the back. This is necessary so that in case of reversing the snowmobile does not bury itself in the snow. Reverse gear on a snowmobile with two skis has to be engaged more often than with one, especially when driving through the forest. |
| New mask | Usually the snowmobile has to be rebuilt by changing its mask. A new mask can be taken from a serial two-ski snowmobile, but you can weld it yourself. |
| Additional fasteners | The skis and steering will have to be secured somehow to the snowmobile frame. This may require additional pipes, rods and other parts. |
Welding is almost always required for the job.
Seat spacers
Spacers for changing the height of the Buran seat are made using high-precision laser cutting and CNC bending. Painted with primer to prevent corrosion during storage and transportation. The raised seat position allows for a more comfortable seating position and leg positioning when riding, which reduces fatigue.
The modification for Buranov versions with a built-in locker lock and hinges is distinguished by ready-made holes for the lock and screws for fastening the hinges.
Both options are made with holes to secure the rise with conventional aluminum rivets, making installation easier. The surface of the seat locker is treated with conventional sealant before installing the lift to ensure that there are no gaps between the seat and the lift.

Tuned exhaust system (resonator with muffler) DD for snowmobile BURAN
Available from 2022. In the 2022 version, the shortcomings associated with placement have been fully refined based on the results of trial operation. The customized exhaust system of the new model is completely located in the right volume of the engine compartment, designed to accommodate the muffler by the Buran manufacturer. Due to the most correctly designed manifold, repeating the slope of the exhaust port, it was possible to slightly increase the power at medium speeds. Peak power remained the same due to the use of the most successful resonator geometry introduced into production earlier. The muffler, as before, can be ordered in exhaust gas outlet modifications: standard, standard as on the Leader, right (through the hood in the area of the manual starter), behind the hood (no need to make a hole, the hood will remain standard). ATTENTION: the system has increased productivity (almost the maximum possible) and has a tilted collector. Therefore, it was originally designed to work with the correct, perfect cooling complex of our design, which has maximum performance. We strongly do not recommend using it with a standard cooling complex!
They have proven themselves to be convenient and easy to install, easy to operate and do not require removal of the system to replace the variator belt. Tests and numerous reviews have shown high power, high efficiency, low noise, and long service life of these exhaust systems. The cost is much lower than other original imported and domestic exhaust systems of similar design and complexity. They are equipped with a modernized exhaust manifold, a resonator with a primary muffler, a final muffler, improved gaskets, springs and fasteners. Those. everything necessary for installation of the system.
Snowmobile "Buran" with two skis: price
There is always a choice: installing 2 skis on a Buran snowmobile yourself or purchasing an existing model. As for the second option, it is much easier to purchase a two-ski model and not worry about modifications. “Lynx”, “Taiga” and most other snowmobiles are already equipped with two skis, they have shown themselves to be excellent when used in Russian conditions, there are enough spare parts for them and their maintenance can be carried out according to a ready-made technological map, without wondering how to fix it later.
The second option, when the owner has a Buran snowmobile and wants 2 skis, is more complex and will require time, effort, and knowledge. Most likely, you will need to purchase spare parts. You will definitely have to buy a new pair of skis. You’ll have to run around car markets, surf on sites like “Avito” or “Yandex-auto” to find some spare parts, and communicate a lot with people. And it is not a fact that the resulting result will be satisfactory.
Is such a scheme necessary if there is a ready-made snowmobile with one ski and there is no desire to buy another? As practice shows, most problems with "planing" of the Buran in deep snow are solved by installing a wide front ski. There is no need to alter anything; this is available at the spare parts store. Maneuverability of the Buran under normal conditions is not such an important task as cross-country ability. Moreover, most fishermen and hunters prefer to spend time outdoors, in the fresh air, rather than sitting in a garage or workshop.
