The Lynx 500 snowmobile is a representative of the products of the Ufa Motor Manufacturing Production Association (UMPO). This manufacturer has been specializing in serial production of utilitarian equipment since 1991. In 2009, the Ufa Motor-Building Production Association announced a complete refusal to produce snowmobiles. The latest model that was released by UMPO is the Lynx 500 snowmobile.
This snowmobile has a trunk with a large capacity, and there is also a high visor that protects the driver from headwinds and various precipitation. All this has a positive effect on operating comfort.
This car was so named for a reason, as it is very fast and at the same time quite maneuverable. In order to ensure smooth movement even on rough terrain, the manufacturer has improved the designs of the rear and front suspension. The wide caterpillar track allows the snowmobile to confidently move both on loose and deep snow, and on crusty snow.

119
The Lynx 119 model belongs to the class of tourist vehicles. It is distinguished by a powerful engine and a high level of design reliability and maneuverability.
The device is equipped with a two-stroke power unit with a forced air cooling system. The engine of this vehicle is made taking into account the Euro-3 environmental fuel standard. The maximum speed is 90 km/h. The instrument panel reflects only two parameters: speedometer; gasoline level sensor.
440
The machine's track mechanism is made of rubberized material and equipped with rods, which will help increase the period of its use.
The 4-stroke power unit is cooled by the penetration of snow into the intake device. If you drive for a long time in an area with little snow, the engine may overheat.
500
The snowmobile is equipped with a 6-gear gearbox and a powerful two-stroke engine. The vehicle is capable of towing a tow hitch whose weight does not exceed 250 kg.
A motor from a Japanese manufacturer is installed here; the engine is made in accordance with the international environmental standard Euro-3. The track device is made of rubber and fabric and equipped with a reinforced rod.
The starting system is powered by an electric starter, which helps start the unit even in low temperatures.
This snowmobile was released in several versions (modifications).
We invite you to familiarize yourself with them:
- 500+. This version is presented as a touring car, but not a work car. It uses a caterpillar track with a width of 500 mm, which ensures good maneuverability on different surfaces. This modification comes with an electric starter as standard.
- 500M. This device is a basic version with a modernized front part, instead of the old carburetor, a carburetor with a 1st chamber made in Japan of the Mikuni type was installed. The basic equipment of this modification includes an electric starter.
- 500MP. This modification has an improved hood and a single-chamber carburetor. In this version, a gear-type gearbox was installed. Externally, the device is completely identical to the previous modification. The basic equipment for the 500MP modification includes an electric starter.
Now “Lynx” has gained great popularity because it allows you to carry out all the necessary tasks, in particular, moving to difficult places.
Sports 121
The sports version is shortened. Due to this, the device increased its maneuverability.
The tracks of the Lynx Sport 121 snowmobile are created with an improved power core - this provides certain guarantees of high reliability of the developed design.
Video
The Lynx 500 snowmobile turned out to be quite multi-purpose, with improved performance characteristics with a fairly powerful and at the same time quite economical power unit. This model is ideal as a workhorse, so it is often used on farms, in forestry, in oil and gas pipeline maintenance, and in patrolling state borders. In snowy off-road conditions, a snowmobile is capable of covering a long distance, dragging sleds and sleds with loads weighing no more than 250 kilograms. Another feature is the ability to operate at fairly low ambient temperatures, namely, the power plant can be easily started even in frosts of minus 40 degrees. The snowmobile performed well in various tests conducted in Yakutia, beyond the Arctic Circle.

Tuning DD exhaust systems for snowmobiles can be purchased in Russia, from companies involved in various developments for off-road vehicles.
Disadvantages of the Lynx snowmobile
Before purchasing, it is recommended to find out about the main disadvantages:
- chain transmission;
- large turning radius;
- rigid suspension;
- engine;
- electrician;
- fuel system.
Owners of Lynx, in particular the 500 model, are experiencing problems with the gearbox chain. It must be adjusted very often: first after traveling 25 km, and then 50 km, during break-in, then after 150 and every 300 km. After purchase, in the 2nd year of operation, the chain in the gearbox and the bolt on the ignition system may break.
Engine problems
Despite good technical characteristics, engines fail. The reason for this is wear and tear. Most often, owners encounter the following breakdowns:
- noises;
- malfunctions;
- increased fuel consumption;
- increased oil consumption;
- reduction in engine power.
Another cause of problems is carburetors; after the manufacturer switched to Japanese ones, most of the problems disappeared on their own.
The weak point of 2-stroke engines is the spark plugs. Oil and gasoline, when mixed, can damage the spark plugs, making it impossible to start the engine cold. Because of this, it is recommended to use several extra spark plugs on a long snowmobile trip. Problems with the reed valves and carburetor can also cause the engine to not start properly.
Electronics malfunctions
The snowmobile begins to stall when there is no spark; if the spark plugs are working correctly, the cause of the malfunction may be the coil. The owner can replace these elements himself.
Fuel system: malfunctions
Incorrect fuel supply and increased or low gasoline consumption are signs of gasoline pump problems; in order to eliminate them, you need to thoroughly clean the part.
A positive quality of domestic snowmobiles is fast and inexpensive repairs that do not cause problems. Original spare parts for all-terrain vehicles can be purchased at many automobile stores, and some of them are similar to motorcycle parts.
Management
The instructions for the Lynx 500 snowmobile contain sections with:
- description and operation of the device;
- storage;
- management;
- a list of faults and ways to eliminate them;
- recycling;
- maintenance.
Before turning on the engine
You will need to check the gas and brake by installing the equipment on the handbrake. Attach the cord to your clothes to stop the engine. After starting the engine, release the brake lock. While using the snowmobile:
- Do not overload it, as this may cause a malfunction;
- It is prohibited to operate the engine at high speeds without additional load;
- It is recommended to prepare the fuel mixture, observing all safety precautions;
- Run-in is recommended (at least 300 km at a speed of 45 km/h without an additional passenger) at speeds up to 60 km/h;
- You should occasionally check the quality of the spark plugs: there should be no damage to the electrodes, it is important to ensure that there is free space between them.
The runners can only be deployed while the snowmobile is moving to avoid damage to the steering wheel.
Power System Maintenance
This procedure includes:
- scheduled maintenance, diagnostics of fastening reliability and quality of connections;
- cleaning the carburetor elements, its channels, as well as periodic maintenance (TO-3);
- washing the fuel tank, fuel lines and filter elements.
Gradual clogging of the filters leads to changes in the operation of the power system - this reduces the quality of fuel purification, and blockages and deterioration of carburetor settings lead to a deterioration in the composition of the combustible mixture at different engine operating modes.
Typical fuel system malfunctions and ways to solve them
Problem | Solution |
Long-term storage of fuel causes an increase in the amount of resins in its composition. This leads to tarring of fuel lines and filter elements, disruption of the mixture composition due to a decrease in the cross-section of the injectors. | It is possible to prevent most breakdowns of the power system if you use only the recommended fuel and oils to create the fuel mixture, maintaining the given proportions, taking into account the necessary requests that are made for refueling. |
Problem | Solution |
Poor quality of connections in the fuel system causes air leaks, which causes the fuel pump to stop functioning normally: a sudden depletion of fuel begins - the engine is quite difficult to turn on and does not work at idle; burnout of the pistons and destruction of the bearing of the lower head of the moving part connecting the piston to the motor shaft is possible. | To eliminate the problem, tighten the fasteners and replace the gaskets. |
Problem | Solution |
Insufficient fuel supply due to a clogged venting pipe in the hot tank. | To remove the intake filter element, remove the fitting. Rinse the filter element without disassembling it. The pump requires reconstruction if there is a malfunction. |
Carburetor adjustment
Complete disassembly of the device is carried out only if it breaks down: with an increase in fuel consumption, an intense decrease in power and excessive operation at idle speed.
Procedure for cleaning and assembling the device:
- The carburetor is dipped in kerosene for 15 minutes.
- The elements are washed well and cleared of resin.
- Washing is done with unleaded fuel. Nozzles with air ducts are blown with compressed air.
- If the nozzles are severely clogged, they should be cleaned with a wooden stick soaked in acetone. You should not clean the injectors with wire, as this leads to increased fuel consumption.
- During the assembly process, each jet is installed in its place.
- To prevent changes in the original shape of the flanges, the carburetor nuts will need to be tightened evenly.
The adjustment is performed after checking the power unit, power system and ignition system settings.
Cases when adjustments should be made
Adjustment is made if the following operational characteristics of the Lynx 500 snowmobile change:
- difficult start;
- unstable idle speed;
- increased fuel consumption;
- unstable operation of the motor under heavy load (jerking in the gearbox while the device is moving).
Carburetor settings are monitored on a warm power unit.

Ask a Question
The carburetor is used with a securely connected receiver. Changes to the structural elements of the receiver must not be allowed. The fuel that enters the carburetor must be cleared of impurities. Parts are washed only with hot liquid; the use of solvent is prohibited. After the work is completed, the product is blown and dried. Cleaning calibrated holes with wires is prohibited.
Adjusting the idle system
Produced on a functioning engine without additional load. Idle speed (idle speed) is adjusted to p=1500±100min-1. Using the XX screw, stable speeds are established, rotating the quality screw (VK) to achieve the highest speed.
The adjustment is repeated two to three times with a gradual decrease in engine speed as the throttle opens. If there is a problem, then enrich the mixture by turning the VK 1/4 turn. If the engine stops working when the throttle is suddenly closed, then lean the mixture by turning the AC valve 1/4 of a turn.
It is necessary to check the quality of the carburetor at speeds that exceed XX speed. To ensure free rotation of the track, you will need to raise the rear half of the Lynx 500 snowmobile by installing a stand.
What is the most successful Lynx snowmobile model?
Modification 119 is the most popular, having passed all tests and proven itself to be positive. The owners noted the good aspects of the wide track, which demonstrates good off-road capabilities, which became useful for hunters, border guards, and geologists.
Model 119 passed all necessary tests. Lynx 119 is suitable for difficult operating conditions, has good maneuverability in deep snow, is maneuverable and dynamic.
The model 119 snowmobile is a deep modernization of the 113, which was developed on the basis of the foreign Arctic Cat. The manufacturers admitted that the copy was unsuccessful due to the fact that the motor did not withstand a high load in harsh conditions. As a result, the question arose about the production of an update to the 113 model.
The 119 has major changes compared to the previous model. The updated transport has become like a tourist one, which means a high level of endurance and high quality. Engineers decided to reduce the displacement of the internal combustion engine to reduce gasoline consumption, power and windows were increased.
Seating position, instrument panel and controls
The dashboard can be safely called “modest”. It just houses the speedometer and fuel gauge. The location of the steering wheel can be safely considered successful. Regardless of the driver's height, driving a snowmobile is very easy. In addition, the steering wheel does not come into contact with the knees, even when making sharp turns. Interestingly, an adult or a child can be located in front of the driver. This in no way interferes with steering the snowmobile due to the large steering wheel.
When the passenger is in the back, he has no way to hold on to anything. There are no special handles provided. In practice, the person behind holds onto the trunk, but this is far from the pinnacle of comfort. The advantage can be considered the spacious footrests, on which even the foot in winter shoes fits perfectly. The seat is quite soft, but it is not very comfortable to sit on. It's easy to slide on.
How to improve the Lynx snowmobile
Often the cooling system needs to be upgraded. If fulfilling all the requirements for changing the oil and adjusting various systems does not produce results, then it is recommended to modify the engine cooling system yourself. The easiest way out in this situation is to insulate the exhaust system. The point of this is to prevent the air from heating up through the collector; in addition, this method reduces noise. Silencers of foreign-made devices are initially packed with materials with a high degree of noise absorption. The right solution is to make a separate supply to the air intake or a heat shield to protect against the negative effects of the muffler.
Now we need to improve engine cooling and reduce cylinder temperatures, in general, install a screen between the output type manifold and the engine cylinders. The purpose of such a device is to cut off air in the cylinders and protect against additional heating. If there is no such solution, it is recommended to use this method: make a plate and install it, regardless of the brand of snowmobile. The effect of the design is noticeable even without the use of electronic temperature sensors of the power unit. The thermal stress of the cylinders is especially greatly reduced.
The latest modification to the cooling system is to increase the speed of the impeller of the device that moves the gas. It is necessary to change the dimensions of the pulley and at the same time use a non-standard dimension of the fan belt, for such an improvement you need to contact a specialist and have the opportunity to select fan belts.
Features of operation
Taiga RM Lynx is not subject to registration with the State Technical Supervision Authority (a passport for the model is not issued), which facilitates the operation process. The snowmobile is intended for use by children from 6 years of age in special areas under adult supervision. It is prohibited to operate the vehicle on public roads.
The safety of Taiga RM Lynx is guaranteed by:
- A special protrusion that reduces the risk of a small driver falling during a sudden start.
- Lever suspension and widely spaced skis make the snowmobile very stable and make it easier to move over uneven surfaces.
- A safety switch with a clothing clip that allows you to quickly stop your snowmobile.
- Low-slung, minimizing the risk of injury from a fall.
- Special reflectors allow you to quickly detect a snowmobile in the dark.
- A flag with the brand symbol complements the design and allows you not to lose sight of the equipment.
Reviews from hunter owners
Before purchasing, it is suggested that you read reviews from hunters about the Lynx snowmobile of different models.
“I bought Lynx in 2014 for 60 thousand, while the average price was 100. Immediately after the purchase, I began to fix all the owner’s problems with great interest. He quickly changed the appearance and got to work on the technical part, repaired the gasoline supply and starter, then changed the spark plugs, and then it started up. Among the positive qualities, I note: high speed, simple design, lightness, powerful engine, cheap, three seats for passengers and luggage compartment, and among the negative qualities: narrow skis, caterpillar tracks, frequent breakdowns and instability in loose snow.”
“In January 2005, my father and I decided to exchange the Buran for a modern Lynx 500+, and the first impressions were good. When compared with the previous model, it is superior in most respects, especially in convenience, the only thing that bothered me was that it requires frequent adjustment of the chain in the gearbox, which occurs at this pace: 25 kilometers, 50 km, 150 km, every 300 km. One winter went well, the snowmobile was accelerated to 80 km/h, the second gear was not enough, it was also inconvenient due to the large radius, and it was also uncomfortable to ride in the tracks of other snowmobiles, since the ski span is 125, with additional pads on the runners.” .
Price
Due to the complete cessation of mass production of the Lynx 500 snowmobile, finding it in a completely new technical condition is quite a difficult task, and it is not a fact that there are still such ones left. Used cars are available for sale and their prices vary from 80 thousand rubles to 150 thousand Russian rubles. The cost for this snowmobile is quite low, since in terms of functionality and performance it can compete strongly with newer imported models of snowmobiles.
