High Fuel Consumption on the Lynx 500 Snowmobile • Dimensional data

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.

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.

• Modification Lynx 500MP. This modification also has a modified hood and a single-chamber carburetor. This version featured a gear-type gearbox. Externally, the snowmobile is completely similar to the previous modification. The basic package for this modification includes an electric starter.

Currently, this snowmobile is also very popular among fishermen and hunters, as it allows you to perform all the necessary tasks, including moving to hard-to-reach places.

Model range of snowmobiles RM

The debut model of the brand was the Lynx 113, the prototype for which was the Arctic Cat car. The copy turned out to be not the most successful, since the snowmobile engine, made using light metals, could not withstand increased loads. Drivers caught the wedge even after a short period of continuous driving.

Preparation for working condition

After unpacking the transport, you need to perform the following steps:

• install skids;
• attach the protective visor to the hood;
• turn the steering wheel.

To attach the skis to the racks, you need to place a support under the front half of the snowmobile, which will reliably support the device at a height suitable for placing the skis under the racks.

Bring the battery into working condition, taking into account the information in the operating instructions. Reinstall the battery and connect suitable wire lugs to the terminals.

Battery storage: turn off and remove the power source, and before storing, charge, check the electrolyte level and its density.

Lynx: what kind of animal is this?. Common lynx

1. The carburetor is dipped in kerosene for 15 minutes.
2. The elements are washed well and cleared of resin.
3. Washing is done with unleaded fuel. Nozzles with air ducts are blown with compressed air.
4. 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.
5. During the assembly process, each jet is installed in its place.
6. To prevent changes in the original shape of the flanges, the carburetor nuts will need to be tightened evenly.

Engine

The Lynx 500 snowmobile is equipped with a gasoline two-stroke power plant. This unit has only two cylinders in the block, the total working volume of which is 0.431 liters. The rated output power reaches 29.42 kilowatts, which translates to 40 horsepower. An air-forced cooling system is used, which allows the machine to be operated not only at low temperatures, but also in warm conditions. The lubrication system uses a special mixture that includes gasoline and oil. This provides the lubricating fluid with frost resistance, which is one of the necessary parameters in harsh operating conditions. The engine consumes about 20 liters of gasoline for every hundred. It is unpretentious in terms of the quality of the fuel being poured, but it is worth noting that gasoline of at least AI-80 is required. The engine is started manually, however, an electric starter can also be included in the package. A non-contact electronic ignition system is used, ensuring smooth and stable operation of the unit under various operating conditions.

Owner reviews

Positive feedback from owners:

• In the winter of 2005, my father and I sold our old Buran snowmobile and decided to find a more improved alternative. And then we came across the Lynx 500 snowmobile. Not only did we like the machine for its design and performance, but another advantage was that it can also be used with 76-grade gasoline (AI-80). In general, we purchased a snowmobile at a cost of 115 thousand Russian rubles. The first impressions of this model were positive, and if we compare it with the same snowstorm, it is noticeable that the Lynx is superior to our first snowmobile in almost all respects: it is more powerful, convenient, maneuverable and simpler. Later it turned out that the car has one weak point, namely the gearbox chain, which very often needs to be tensioned again. As for the rest, we are quite pleased with the technology. So far there have been no serious breakdowns.
• I bought Lynx 500+ and didn’t regret it at all. The snowmobile starts perfectly regardless of weather conditions. Personally, I have successfully and quickly started the engine many times at a temperature of minus 35 degrees, which is good news. The snowmobile is also very resistant to rollovers on slopes, which is due to the wide-spaced front skis. My configuration has heated steering wheel grips, which prevents your hands from freezing. Among the shortcomings, I would like to note that the engine is a little weak, and the gearbox does not have a neutral speed. The equipment is very reliable in operation. Once I reached a maximum speed of 80 kilometers per hour, and the snowmobile confidently stayed on the surface. But as the manufacturer claims about 20 liters of consumption per 100 kilometers, this did not happen. Consumption is much higher even when used in gentle mode.
• I bought this snowmobile in the spring for half the price. All summer I waited for winter to come so I could test the purchase, and finally it happened. At the beginning of operation, no problems were identified, which was surprising, since I bought a used one from 2004. After the purchase, I replaced the variator belt with a Kevlar one. I drove every day for several hours for a month, before the first problems appeared. The return spring in the “kick starter” has flown (there is no electric starter...). But we still managed to fix it.
• The advantages of this snowmobile are immediately clear. The market price, accessible to everyone (ranging from 80 thousand rubles to 150 thousand Russian rubles), will not cause large financial costs for maintenance. There is a speed for rear movement, which is very convenient off-road. There is also airflow for the steering wheel handles and legs, and a roomy seat. So far I have noticed the following shortcomings: poor placement of voltage regulators, which leads to oxidation of the terminals and loss of spark at the candles, and weak headlight switches, which is why many people connect directly, but this leads to a more difficult engine start when cold. Otherwise, it’s a good device, superior in appearance to the well-known Buran snowmobile, but slightly inferior to it in technical characteristics.

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.

How to improve driving performance?

To do this, you need to take care of the chassis, sometimes checking all the elements and monitoring the tightness of the fasteners.

Snow slightly wets the metal strips of the runner. Prolonged driving on icy snow can cause severe damage to the linings. In this case, they will need to be replaced by disassembling the track suspension.

Carry out the work in this way:

• unscrew the tension bolts;
• remove the bolts from the levers;
• tilt the equipment, pull out the suspension, change the skid pads.

To remove and then install the linings, you can use a wooden block and a hammer; assembly is carried out in the reverse order.

It is possible to improve the driving performance, ease of use and efficiency of a snowmobile by replacing standard parts or tuning them. With the help of a wide off-road track, maneuverability and maneuverability through snow drifts are significantly increased.

Distinctive features of the model

The Lynx 500 snowmobile is the latest model produced by the Ufa Motor Production Association (UMPO). For connoisseurs of this manufacturer, the model is a real tidbit: since new cars are rarely found in stores now, connoisseurs of inexpensive but functional motorcycles are on a real hunt even for used copies.

They love the Lynx 500 snowmobile for its powerful and at the same time quite economical power “stuffing”. This model can be used as a workhorse, so it is often used on farms, forestry, oil and gas pipeline maintenance, and state border patrol. In snowy off-road conditions, a snowmobile is capable of covering a long distance, dragging sleds and sleds with loads of up to 250 kilograms.

Another feature of the Lynx 500 is the ability to operate at fairly low temperatures. The power plant can quickly start even in frosty conditions of -40 degrees. The snowmobile performed well in tests conducted in Yakutia, beyond the Arctic Circle.

The Lynx 500 snowmobile is also very popular among fishermen and hunters. It is valued because it allows you to perform all necessary tasks, including moving to hard-to-reach places.

Operating experience and features

Despite the success of the 110 model, reviews of the Lynx 150 ATV are far from ideal. Equipment owners, tempted by the affordable price, found a number of design problems:

• Poor build quality. In almost all devices the bolts are not tightened properly. If you don't tighten them right away, the car begins to fall apart while driving. Basically, the anthers fall off and the chain tensioner unscrews.
• Shaking. At low speeds the device behaves perfectly, but after the 35 km/h mark the car begins to vibrate. Because of this, problems arise with the main lighting, bolts become loose, etc.
• Poorly designed brakes. The factory assembly leaves much to be desired, so the user needs to independently inspect the mechanism and carry out alignment.
• Low load capacity.

Immediately after purchase, the owner of the Lynx 150 is recommended to carry out a full technical inspection, tighten the boots, change the brake pads, front hub seals, and secure the tie rod boots. Spare parts for domestic devices are cheap, so you can spend a couple of thousand rubles. With proper operation and timely maintenance, the machine will operate without serious breakdowns for 1-2 years.

• Good maneuverability. Lynx 150 drives through mud, sand, and confidently handles off-road conditions.
• Controllability. The ATV confidently takes turns and does not try to cover the rider. The playful and maneuverable horse is suitable for teenagers and children over 10 years old.
• Powerful LED lighting.
• Reasonable price. A new device costs about 90 thousand rubles.

The stylish device does not need tuning. Of course, users dream of installing a trunk, a comfortable seat, a durable bump stop and other body kit, but it all comes down to carrying capacity. The maximum load of the device is 75 kg, which eliminates the possibility of modernization in the bud.

Engine Lynx 500

The snowmobile is equipped with a gasoline two-stroke power plant. It has only two cylinders in the block, the total working volume of which is 0.431 liters. The rated output power is 29.42 kilowatts (40 horsepower). The forced-air cooling system allows you to operate the machine not only at low temperatures, but also in hot weather.

The engine consumes about 20 liters of gasoline for every 100 km. It is unpretentious in terms of the quality of the fuel being poured, but still experts recommend using gasoline no lower than AI-80. The engine is started manually, but it is possible to install an electric starter.

The Lynx 500 uses a non-contact electronic ignition system. It ensures smooth and stable operation of the unit in any operating conditions.

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.

How to set the ignition on a Lynx 500 snowmobile

For high-quality engine operation in hazardous conditions, you need to perform the correct settings. Before adjusting the ignition system, you should take into account the following parameter during the adjustment process - setting the advance angle (TAA).

To adjust the ignition, use the following tools:

• strobe;
• screwdriver;
• spanners;
• paper sheet;
• protractor ruler;
• compass;
• metal strip.

According to the instructions, draw a scale and mark the degrees on it, then draw a circle on paper so that its diameter matches the size of the fixed element of the mounted variator on the device. The central part of the circle is the middle of the edge of the crankshaft.

1. Using a protractor, write the degrees - minimum 0 and maximum 30, the marks are counted from the point that is equal to 12 o'clock on the dial, clockwise. Transfer the prepared drawing to the strip and attach it to the engine cover. Please note that the motor must be cooled beforehand.
2. Place the left piston of the engine in the “dead” position, but first unscrew the spark plugs.
3. Install a screwdriver into the well.
4. Turn the variator by hand while rotating the rod (shaft), while simultaneously watching how the screwdriver moves in the well. She should stand for a moment and immediately continue moving in the other direction.
5. After reaching the dead center, mark the point on the variator so that it is located opposite the “0 degrees” value, which is marked on the OZ scale.
6. Connect a strobe light to pick up the signal from the wire. Mount in the spark plug position and turn on the engine.
7. Point the stroboscope lamp at the scale, start the engine with an electric starter and increase the speed to maximum values. When reaching high speeds, the lamp should flash when a spark appears. This means that there is a coincidence with the scale mark on the variator, and the ignition timing can be determined.

To adjust the ignition timing, you need to turn off the engine, loosen the magdino screws and turn the base of the latter to the desired amount. Repeat the angle check using the strobe light.

Turning the base clockwise will make the lead angle smaller, and counterclockwise will increase it. A shift of 0.9 mm corresponds to a change of one degree.

After the replacement has been completed, the base of the magdino needs to be checked, the ignition timing must be set, and marks applied to the body part. At maximum engine speed, the ignition timing should be 21-23 degrees. In addition to high speeds, additional SOP can be checked at idle speed - 14-17 degrees and at start speed - 8.5-11 degrees. To set the correct parameters, you need to use a universal tachometer. Priority readings: the position of the magdino base, which provides the desired angle at high speeds.

Snowmobile price

Due to the cessation of mass production of the Lynx 500 snowmobile, finding it in a completely new technical condition is quite a difficult task (the model is not for sale on the official website). If you are lucky enough to find a car in the warehouse of some store, you will have to pay 185,000-210,000 rubles for it.

It is much easier and more economical to get used snowmobiles. The cost for them varies from 80,000 to 150,000 rubles (depending on mileage). As a rule, even Lynxes that have been used for a couple of seasons still serve well, as they retain their excellent driving and cargo qualities for several decades.
