ATV from OKI - how to make it yourself and not regret it?

ATVs have been and remain a very popular means of transportation. This is a kind of hybrid that combines all the best qualities of a motorcycle and a tractor. ATVs gained major popularity in farming and youth circles. This is understandable, because it is a stylish, fast and reliable way of transportation. ATVs are well suited for extreme sports due to their high seating position. On an ATV, moving over rough terrain feels the same as driving a car on the highway. The main problem is that an ATV is quite expensive. But if you are limited in funds, this is not a reason to give up on your dream. One of the options for its implementation: make an ATV from oka.

SUV from Oka: what to watch out for

As practice shows, the all-terrain vehicle also has weaknesses and vulnerabilities.
Engine oil consumption increases, especially if you often overcome water obstacles. Some owners of such all-terrain vehicles note rapid wear of the rubber. There shouldn't be any problems with the frame, but it's best to play it safe and double-check the welds. It is best to cover all mechanisms and parts with protective material or paint to avoid corrosion. Due to sloppy connections, water can get inside the car, which will soon cause a problem. It is necessary to additionally install special protection on the engine sump. Some car enthusiasts specifically attach foam to increase the buoyancy of the vehicle. If the designer decided to leave springs instead of springs, then there is a high risk of their rapid wear. It causes roughness and discomfort for passengers while driving off-road.

DIY ATV frame drawings

The false tank has a complex shape. It was not possible to bend it out of hardboard. Therefore, having wrapped the engine with plastic film, I began to fill the space intended for it with layers of polyurethane foam. After each layer, drying is mandatory, otherwise the thick volume of foam may not dry out inside. Filled until the layers went beyond the contour. Finally, after the foam had completely dried, I began to draw out the desired shape with a knife. The edges were smoothed with coarse sandpaper.

Preliminary design stage

BMW xdrive all-wheel drive
The following parts are taken from the Oka car during design:

• Motor;
• Transmission;
• Wheel axles;
• Steering.

If necessary, elements can be replaced with compatible ones and some connections can be modified.

A mini tractor from an Oka walk-behind tractor is constructed on the basis of a channel No. 6-8 or a corner 4x4 centimeters. The amount of necessary materials is determined according to prepared drawings with the exact dimensions of the elements.

You need to acquire the following tools and materials:

• Bulgarian;
• Welding machine;
• Screwdrivers and keys;
• Sheet metal;
• Tires and wheels with a diameter of 13-24 inches;
• Operator's seat. You can use not only a car seat, but an office chair. It is fixed to the frame of the unit.

Design feature

The main purpose of a sports car is to drive on difficult dirt tracks with sharp exits and entrances. Why is it best to choose Oka? Firstly, the original purpose of the car is to drive on sandy terrain. Secondly, the Oka car is ideal for a buggy due to its design characteristics. Although buggies are classified as sports SUVs, this car is nevertheless very safe and comfortable.

The driver's seat is equipped with special sports seat belts.

Due to the fact that the design of this car mainly consists of frames, it is not afraid of deformation even in conditions of extreme and aggressive driving; the driver will not suffer in case of accidents. In truth, you can use not only Oka as a donor car, but also Zaporozhets or Niva 4x4 . In the latter case, the car will be heavier, but with all-wheel drive. However, for light models, a car with an engine capacity of 750 cubic centimeters or more is quite suitable. The buggy can also be made with all-wheel drive.

Oka engine tuning

Duster all wheel drive

The process of improving engine performance can be divided into 2 directions:

• A radical change in characteristics - a complete replacement of the motor
• Improving the standard power unit

In the first case, the ideal option would be a 1.3-liter injection engine from Rover Mini. The advantage of this type of tuning is a significant increase in technical indicators; the disadvantages are the high cost of implementation and the need to rework most of the car’s systems for a new engine. It's expensive and time consuming.

The second option - upgrading the standard power unit - is cheaper and simpler, but will not allow you to obtain such an increase in power as in the first case.

Do-it-yourself Oka engine tuning must begin with the carburetor. The first step is to increase the throttle body diameter to 52–54 mm. This will allow the engine to receive more air, which will make its operation easier, improve performance and increase engine life. You can immediately install a tuning modification of the carburetor.

Installing a new camshaft allows you to increase the speed to 7000 units. In this case, it is necessary to increase the engine power, which is done using the following operations:

• Replacing standard valves with lightweight ones
• Valve seat upgrades
• Modification of inlet and outlet valve channels
• Sealing valves
• Installation of bronze guides
• Changing the shape of combustion chambers

Additionally, it is necessary to replace the intake and exhaust manifolds with sports modifications, as well as the air filter with a K&N model with zero resistance. This set of measures will significantly improve the technical characteristics of the engine and optimize its operation, that is, the loss of power will be minimal.

The muffler attachment can be used to give the engine a sporty growl. Illuminated models will create the effect of a flame escaping from a jet nozzle.

How to make an SUV on tracks from the Oka?

Seven in the snow: whose all-wheel drive is better and whose rear row is wider

Creating such an all-terrain vehicle is quite difficult and expensive. Caterpillars from the Buran all-terrain vehicle are suitable as a running element. You can also make them yourself, but for this you need to have the appropriate skills, materials and time. The drive shafts are also taken from the specified model, since the variable gearbox will be optimally combined with the braking system of the future Oka SUV.

The car's own CV joints will be used. Connecting and connecting the brake discs is not difficult. Identical manipulations are performed on the front shafts. Experts recommend mounting the brake unit in the front of the car. After completing the specified work, the functionality of all main elements and their fastenings is checked. If the first tests do not raise any complaints, you can move on to field testing of the all-terrain vehicle. On some modifications, craftsmen put tracks on each wheel. Among the advantages of this design is the reduction in the total weight of the vehicle. In this case, grip on the road surface will deteriorate.

Preparation for work, tools and equipment

First of all, you need to carefully consider when, where and for what purposes the future ATV will be used - hunting and fishing, motorcycling in nature, transporting goods, etc. It is on this basis that you need to make a choice of a “donor” vehicle, deciding how powerful the engine is needed, what kind of suspension is suitable, what kind of trunk, etc.

You can take ready-made drawings from the Internet, create them from scratch yourself, or combine both options and ready to remake them at your own discretion.

List of required tools:

• welding machine;
• Bulgarian;
• drill;
• a set of keys;
• various small tools - calipers, hammer, knife, screwdrivers, pliers, etc.

To make your own frame, you will also need equipment for bending pipes. If you don’t have one, you can rent it or outsource the necessary work to another craftsman. Only with remarkable skill can you bend the pipes manually by heating the bend with a gas cutter or torch.

• engine;
• frame;
• rear and front suspension;
• steering;
• brake system;
• cooling system;
• muffler;
• electrical equipment - battery, headlights;
• body, body kit

It is quite possible to make a muffler yourself. Everything else is to purchase used parts on the shadow market.

Small KAMAZ

Although the development of the small car was carried out in Serpukhov, it was supposed to be launched into mass production in Elabuga, and since the city is located on the Kama River, the model was given the name “Kama” VAZ 1111. But due to the unstable economy then in the Soviet Union, there were no plans not destined to come true - the production of the brand in the planned volume (900 thousand cars per year) did not work out, and the Elabuga plant was repurposed. VAZ-1111 began to be produced in smaller volumes, and at other enterprises:

• at the Volzhsky Automobile Plant in Tolyatti;
• in Serpukhov (SeAZ);
• in Naberezhnye Chelny (ZMA).

In Togliatti, the production of a small car did not last long - its production on the main AvtoVAZ conveyor was unprofitable, and in 1995 the Oka was removed from the assembly line. The small car plant (ZMA) in Naberezhnye Chelny produced Oka until 2005, and the letters “KAMAZ” were proudly displayed on the nameplates of small cars.

Lada Oka All-wheel drive Syncro › Logbook › all-wheel drive gearbox is ready

Let me remind you: the most important task was to make the same shank for transmitting torque to the bevel gear, this operation is not simple, and most importantly there were very serious concerns that this unit would not fall apart on the first exit, in the end the decision was made to implant gearbox VAZ differential housing from the Passat. they look almost alike

It would probably have been easier to just attach the entire VW box at once, but it is very heavy, and most importantly, I need a lowering pair because the car is built for driving on dirt roads, light off-road and for household needs (pulling a trailer) in fact, here is the “tuning main pair” with a ratio of 5.3 instead of the standard 4.1

The differential housing was modified many times on a lathe in order to fit into the gearbox housing. It was necessary to modify both the housing itself and the bearing mounting locations

The bearings themselves from the VW differential are installed through adapter rings

As I already said, the differential housing was machined several times in order to go as deep as possible to the bottom without touching the crankcase walls. The final operation was to measure the gap between the crankcases and groove the bearing so that no distance shims were required

I also had to modify the planetary gear because it should be attached to the VW differential housing on one side and on the VAZ on the other

I also had to prepare a diff housing for mounting on the other side for the planetary gear

According to the law of meanness, the holes for attaching the gear to the body were a multiple of the number of bolts but with different diameters. Having drilled the necessary holes, the problem arose that the edges of the bolt heads rested against the body, I spent a long time looking for bolts! I found only one version of bolts with an internal hexagon with a hardening number of 12, but a package of 100 pieces for 50 rubles each... in the end I had to be content with bolts from the ball basins of the new model, which everyone criticizes so much for the fact that they are for Torex. By the way, I also had to look for bolts because They don’t come with a ball joint and aren’t available in stores. They have a hardening level of 10, but I hope that they’re enough for a stock motor. Anyway, I had to slightly mill the body for the bolt heads.

on the reverse side the bolts had to be trimmed with a grinder

of course I changed the bearings and seals in the box and put everything back together

"Lenekhod"

Just by the name of this transport, it becomes clear that its author and designer was a master named Leonid. Indeed, a resident of the city of Nyagan, who built such a miracle of technology, capable of accelerating up to 50 km/h and overcoming any water barriers, bears this very name.

If we talk about the technical characteristics of the snowmobile, then it was built on the body of the same Oka, placed on an all-welded profile frame, receiving a motor from a VAZ-1111 as a power plant.

The result is a real hodgepodge of meat, and even on studded SHAIN tires, but the car copes with its duties with a bang, helping the owner transport firewood and other cargo.

Examples of Oka SUV

Often users turn on their imagination, which amazes the imagination of professional automobile designers. Basically, the alterations differ in design, chassis elements and wheel sizes. Often, low-pressure tires are installed on a car, which improve the vehicle’s off-road capability.

The base of such cars, as a rule, consists of the chassis of other vehicles. To install wheels with a large radius, the wings are cut off; some Oka SUVs undergo body modifications. All manipulations are aimed at giving the car an original and presentable exterior. In addition, craftsmen beautifully straighten and paint the joints.

As an option, you can install protection for the bottom of the all-terrain vehicle. The low-power engine of the original is replaced with more powerful analogues. This is one of the most complex and time-consuming processes when improving a small car. In general, there are modifications that are not embarrassing to present at international exhibitions.

In conclusion

It is difficult to imagine that Oka can act as an all-terrain vehicle. Nevertheless, ingenuity and resourcefulness make it possible to create a real off-road conqueror out of this “baby”. Full-fledged Russian-made SUVs, not to mention foreign-made grandees, are very expensive. Converting a “compact car” into an all-terrain vehicle also requires considerable expenses. However, many consumers are confident that “the game is worth the candle.” First, the transformation can be carried out in stages. Secondly, you can easily find spare parts, as well as use improvised means and parts from non-working cars.

Among the most popular homemade versions of the all-terrain Oka, Fr. They are based on low-pressure pneumatic wheels. The originality of the tracked models is that they are perfect for snowy and sandy areas.

Tuning VAZ 1111

Tuning Oka (VAZ 1111)

The VAZ 1111, better known as Oka, became the subject of ridicule due to its compact size and simple design. Meanwhile, this car anticipated the era of economical, small cars. Today, almost every global automotive brand is developing its own “baby car”, so serious competition has unfolded in the class of compact cars. The domestic auto industry, along with the Italian one, can be considered a pioneer in the development of the production of compact cars. Another question is that the VAZ 1111 has not received sufficient development in the form of the development of restylings and new generations. But Oka provides fans with car tuning with their own hands and ample opportunities for modernization.

There are many options for transformation and restyling of the VAZ 1111:

• SUV
• rally car
• Retro car - design concepts of the late 60s and early 70s of the XX century are determined by the angularity of body shapes and the use of bright colors in design
• Cabriolet
• Roadster

The simplest and most accessible is tuning the Oka for off-road use, since the car’s appearance is similar to this class of car. To enhance this effect, it is enough to lift the suspension, install larger diameter wheels and tires with a powerful tread. But tuning the Oka for a jeep is not limited to the above changes; they can be considered only the first stage in creating an exclusive little all-terrain vehicle.

https://youtube.com/watch?v=PxH6b8pJfZ8

External tuning of the Oka can be styled after the popular Grand Cherokee SUV model. This is facilitated by the similarity of the headlights and radiator grille. In both cars they are oblong, rectangular in shape. It is enough to install a body kit, wheels with a large diameter and tractor tire tread, as well as give the hood the appropriate configuration and the nondescript OKA will turn into a miniature clone of an SUV popular in the 90s.

Tuning Oka cars with your own hands is quite easy. This is due to the simplicity of the technical structure of the car and its unpretentious appearance, which, on the one hand, makes modernization simple and cheap, and on the other, allows you to carry out all kinds of experiments on the car. From all of the above, we can conclude that tuning a VAZ 1111 is the best school for a beginner and a kind of creative studio for an experienced master.

Tuning the Oka's interior

There are more than enough options for modernization:

• Complete replacement of interior trim. To do this, use your own materials or buy a special set. You can try the author’s method of reworking the interior, for example, modifying the standard trim
• Partial decoration - installation of shaped inserts and elements in the cladding
• Modification of standard seats - installation of comfortable headrests, purchase or production of stylish covers. In this case, the general design concept of interior redesign in terms of color selection should be taken into account
• Replacing standard seats with sports or executive seats
• Installing a new steering wheel
• Installing stylish pedal covers
• Installation of additional equipment: automatic windows and side mirrors
• The roof can be made panoramic or a hatch can be cut out

These are not all the options that can be implemented when tuning the Oka’s interior with your own hands. In fact, there are no dogmas or prohibitions here; everything depends on the imagination of the master. This is an excellent option for carrying out creative experiments and inventing original decorating techniques.

How to make a homemade wheeled all-terrain vehicle

An example of a drawing of an all-terrain vehicle on low-pressure tires

It makes sense to equip the basic unit with a reduction gearbox. The reason is that gasoline and diesel engines have the best torque performance at a crankshaft speed of approximately 75-85% of the maximum.

All-terrain vehicle frame

An example of a frame-fracture drawing

A frame is created between the front and rear axles. It is better to use profile pipes of rectangular or square cross-section as the basis. They provide greater rigidity than rolled angles, channels and I-beams of the same mass.

The joining of the frame elements of a wheeled all-terrain vehicle can be rigid, then it will be formed in a single-volume format. When using heavy Neva or MTZ walk-behind tractors, this option will be preferable.

As an option, a breakable frame (fracture) is made; this option is used for areas with a complex profile. Here the articulation is performed through the kingpin. The front and rear axles have independent suspension from each other. Craftsmen create such all-terrain vehicles based on the Neva and Ugra walk-behind tractors.

Rear axle and suspension of a homemade all-terrain vehicle

To simplify the design, some DIYers use a ready-made rear axle from a passenger car. For example, from the Moskvich-412 car: its low weight allows installation on a light all-terrain vehicle. The suspension is performed on shock absorbers for a smooth ride and reduced vibration.

Other craftsmen make independent suspension on each rear wheel. This approach is implemented on the Ant scooter. When driving, a slight rocking is felt, at the same time the wheels experience less resistance on uneven surfaces, and fuel consumption is noticeably reduced.

The rear axle is connected to the frame with long, hardened bolts. For elastic joints, rubber inserts are used, for example, silent blocks. This improves the performance characteristics of an all-terrain vehicle based on a walk-behind tractor.

Wheels (low pressure chambers)

To move on wet and unstable ground, you can use lugs. They provide high grip. Large-diameter low-pressure chambers perform even better. Pneumatics have minimal ground pressure, and the presence of air contained in the all-terrain vehicle’s chambers will make it possible to create a floating all-terrain vehicle.

For installation on the rear axle, homemade or special wheels for all-terrain vehicles, swamp vehicles and snowmobiles are used. They can be purchased assembled or as separate elements: tire, tube, disc. The wheel is easy to assemble.

1. Homemade discs for pneumatics are made by welding ordinary discs and mounting plates using metal tubes. This expansion is necessary in order to adjust the small diameter of the car rim to large cameras and better fix them.
2. A large camera is placed on a specially expanded disk - either a proprietary one or from other units (GAZ 53, Ural, Kamaz or another truck, an aviation camera, etc.).
3. An air valve is installed in the hole of the disk.
4. The wheel is inflated with air.
5. The resulting tires are installed on a homemade all-terrain vehicle.

You can increase the cross-country ability of regular wheels on low-pressure chambers by creating an additional tread. For example, additionally secure the cameras with chains, conveyor belts, homemade tracks or another method.

Another option is to cut a patch lug from the tire. The depth of the structure’s hook reaches more than 20-25 mm. Rolling resistance increases, while at the same time the slip coefficient decreases sharply.

Assembling a homemade all-terrain vehicle from a walk-behind tractor

When all the tools, spare parts and components are prepared, you can begin assembly. This is a rough plan for how to assemble a homemade all-terrain vehicle, it all depends on the chosen design.

1. A walk-behind tractor is installed on a welded or finished frame.
2. The rear axle and, if necessary, the front axle are mounted.
3. The seat is placed on the frame.
4. If provided in the drawing and diagram, the steering control is installed.
5. The protection is attached to the frame; it is made of plastic or metal sheet.
6. The future driver should try out the comfort of the seat; if necessary, provide auxiliary devices for adjusting the seat.
7. The functionality of the brakes is checked.
8. Electrical circuits and lighting fixtures are installed.

After completing the bench tests, they begin the field tests. You need to know how the car behaves in difficult conditions.

Selection of systems

The brake system uses new parts or with minimal mileage. It is dangerous to install old brakes. The muffler is removed from the old car or made independently from a pipe. If a frame from another machine is used, it must be securely bolted to the bottom of the motor. The power unit is installed at the rear or front. Experts advise securely attaching the drive and transmission to the frame.

If the frame requires reconstruction, the component elements are dismantled. The front part needs to be extended onto the frame. At the next stage, the components of the frame are welded. When reconstructing the frame of a motorcycle, the seatposts are moved back by 40-45 cm. Racks are cut out of metal and welded, which are then fixed to the frame. The resulting homemade quad part can be painted with any paint.

To make your own frame, use a regular pipe with a wall thickness of up to 3 mm. It is better to make the spars from a pipe with a diameter of 25 mm, and the struts from a 20 mm pipe. The elements are fixed by spot and then solid welding. In a similar way, the ears from the levers and shock absorbers are welded to the frame. It is recommended to fix the brackets when installing other components and assemblies.

Thoughtful solution

Since in rural areas you often have to navigate difficult terrain, many people want to buy an SUV. Alas, such cars are quite expensive, so you need to know how to make an all-terrain vehicle from the Oka. To create it, they use improvised means, which include spare parts from broken cars and motorcycles.

Among the most popular options for “folk” crafts are “station wagons” based on low-pressure pneumatics or air-cushioned ones. The use of crawler tracks is also common, but they are more suitable for snowy areas. Creating an SUV based on the Oka is a cost-effective solution, since it does not require the purchase of expensive components.

All-terrain vehicle on low-pressure tires

This design is based on an invention that uses a body that is located on a breakable frame. This solution significantly strengthens the design of the product. All wheels are installed with your own hands as drive wheels, so they can even overcome swampy terrain.

Based on Oka engines, the production of so-called karakat engines is also very popular. They stand out for their increased cross-country ability thanks to wide-format tires. This complements the advantages of pneumatics, because it does not destroy the grass cover.

Using Tracks

These “station wagon” options are most popular among fishermen and hunters. Homemade tracked all-terrain vehicles from Oka have increased maneuverability in water bodies and wooded areas. Their body is usually made of a box structure, which reaches a length of 3 meters. It is light in weight, so in places where deep traces of a person remain, vehicles penetrate into the quagmire only 10 cm.

Operating rules

According to safety requirements, all responsibility falls on the driver, so when driving a buggy you need to rely on the rules of the road, operating rules and your common sense. So, you purchased a buggy, and the most basic rule is that children under 16 years old are prohibited from driving; they can only ride in the car as passengers. The rest of the rules are as follows.

1. When riding a buggy, it is mandatory to wear protective equipment, a helmet, gloves, shoes for the season, a protective mask or goggles.
2. The correct seating position must always be maintained - hold the steering wheel with both hands and your feet on the pedals. The driver and passengers must wear seat belts.
3. Before driving, carefully look around for the presence or absence of obstacles to your movement.
4. Learn the hand signals, they are all written down in the “Rules of the Road”, this will be very useful in case of any situations that arise on the train.
5. When crossing a road, always stop, check the road for other traffic, and only then cross.
6. When moving in a group, maintain a distance of 40-50 meters.

Buggy as a means of transportation has a number of advantages and disadvantages. It is mobile, safe, economical, lightweight and has excellent cross-country ability.

At the same time, it has no external aesthetic appeal and an open design. All the shortcomings prevent the car from being used for everyday use, but it is ideal for touring trips and extreme racing.

See what the Oka buggy looks like below.

what's wrong, it's just a normal road for my little girl)

Oka is not an SUV. Verified. We need to collect 4wd. I made it easier, bought Niva 3D

We are not looking for easy ways, and in fact it was interesting to try to assemble something with our own hands)

It’s fine, but put on other tires and it won’t go anywhere

It will go, the differential is welded)

The other one got dirty for the winter, I took off the Simex, put on the Goodrich and went for a ride, and I don’t take off the Simex anymore

It will go, the differential is welded)

Also brewed in front

How much do these tires cost?

I bought 2 sets of used tires, for 1000r and 3000r

On Avito I saw such kits selling for 35 k, I think.

Yes, but it was expensive for us, so we assembled everything on our own and spent 7k, including tires and body painting)

Well, it turned out okay) But it’s not official? )

No, front-wheel drive with welded differential)

Well done! Not everyone will decide to redo it. And it’s easy to scratch with your tongue!

I have an okushka) it will go through such mud and on ordinary wheels, suspension and tires)

the cheaper the car, the less a pity it is to kill it and the higher the cross-country ability)

Here at the opening of the hunt in the spring, Muscovites on Kruzak 200s and X6 boomers are bludgeoning through the swamps.

for them the price of those cars is like dust...that’s why they kill

Here at the opening of the hunt in the spring, Muscovites on Kruzak 200s and X6 boomers are bludgeoning through the swamps.

Well, not only you. We regularly drag such “hunters” out of shit. They are imported and they are expensive. They don't give a damn about knee-deep dirt, they talk through their lips. And when they come running “save, help!”, such people immediately become simple. I know a driver who spent 4 (four!) days in a salt marsh on Cayenne, and who the hell helped him. For during the day (at the opening of the hunt) this creature was rude to everyone he met, opened his hands a couple of times and was beaten. Listen to him - and his brother is a minister and he opens the door to the president with his feet and is the uncle of the general of all generals. And why is he hunting here, and the rest are rabble and go to hell! In my life I will never pull out these show-offs again. Normal men come up and ask in a humane way - I will always help you out. And these here will buy tough guys, but in the head it was like a cast bone, and remains so. They don’t ask, they just order, you fucking boyars! - “Whose UAZ, come on, pull me!” And fuck you with a thick layer and all over your makeup! Go ahead on foot behind the tractor!

At first glance, the Oka SUV sounds a little strange? However, this car from VAZ designers, which has gained popularity due to its compact dimensions and low fuel consumption, can easily be converted into a jeep. Now the car is not mass-produced, however, it can be found on the roads in different modifications. "Small car" is an excellent springboard for experiments. Let's look at the features of creating and maintaining this little “monster”.

Engine tuning

Modernization of the Oka engine is conditionally divided into two directions:

• Replacing the motor.
• Improving the characteristics of the standard power unit.

The ideal option for converting the Oka to an injector is to install a 1.3-liter engine from a Rover Mini. Modernization allows you to increase the technical characteristics of the car, but the cost of the work is very high, since most systems need to be redesigned for a new engine.

The second option is to improve the engine. It is cheaper, but does not allow you to achieve such an increase in power as the first one.

Modernization of the Oka engine begins with the carburetor, namely, increasing the diameter of the throttle valve. This facilitates the operation of the motor, increases its service life and technical characteristics. Instead of increasing the throttle, you can immediately install a tuned version of the carburetor.

An increase in the number of revolutions to 7000 units is possible thanks to the installation of a new camshaft. At the same time, the engine power is increased:

• Lightweight valves are installed instead of standard ones.
• Modernization of valve seats;
• Improved valve inlet and outlet ports.
• Sealing.
• Installation of bronze guides.
• Reconstruction of combustion chambers.

The intake and exhaust manifolds are replaced with sports analogues, the air filter is replaced with a K&N model with zero resistance. The work allows you to improve the technical characteristics of the engine and minimize power losses.
