We are constructing a cross-country motorcycle based on Izh Planet 4

The fifth generation Jupiter has a significantly modernized engine. The valve timing has been more favorably selected, the cylinder purging has been optimized and the traction and dynamic characteristics have been improved. The power unit of the new IZH Jupiter-5 motorcycle model copes better than its predecessors with increasing resistance speed, which is important when driving with a sidecar on country roads.

The maximum torque has been increased from 3.4 to 3.5 and is achieved at 600-900 rpm less than before. Although the maximum power, compared to Jupiter 4, decreased by 4 hp (from 28 to 24), the power at the most running, medium speeds increased slightly - by 2 hp. The rotation speed corresponding to the maximum power in the “5” model is reduced to 4800-5600 rpm at 5600-6200 rpm for Jupiter-4.

It is pleasantly pleasing that when fully loaded, IZ Jupiter-5 easily picks up speed and feels confident in higher gears, which allows you to switch them much less frequently than in its predecessor. This aspect will appeal to both rural and urban motorcyclists.

Fuel consumption for the single model is 5.9 l/100 km instead of the previous 6.2 and 7.1 instead of 7.5 l/100 km with a sidecar.

Changes in the design of the cylinders and the fins of the heads made it possible to reduce engine noise. In general, the unit has become more reliable due to increased wear resistance of the piston rings, improved crankcase sealing, improved kick-starter mechanism and ratcheting mechanism in the clutch drum.

Engine IZH Jupiter-5-03

The IZ Jupiter-5 liquid-cooled engine differs favorably from counter-air cooling in that it can operate for a long time in extreme mode at high ambient temperatures. This allows use in stationary installations without external airflow. At the same time, the technical, economic and environmental parameters of the motorcycle are increased.

Piston water cooling of the motorcycle IZH Jupiter-5-03 (IZH 6.113-03): 1 – generator cover; 2 – right crankcase cover; 3 – generator; 4 – seal with right cover; 5 – right crankshaft; 6 – right half of the crankcase; 7 – flywheel; 8 – crankshaft seal; 9 – crank chamber cover; 10 – left crankshaft; 11 – left seal; 12 – right half of the crankcase; 13 – crankshaft sprocket; 14 – right crankcase cover; 15 – water pump; 16 – cylinder; 17 – spark plug; 18 – cylinder head; 19 – piston; 20 – connecting rod.

The IZ Jupiter-5-03 liquid cooling system with forced liquid circulation includes: - special cylinders and cylinder heads with cavities for liquid circulation; — cylinder head covers; - manifold with thermostat; — water pump with drive; — a radiator with an expansion tank and steam-air valves in the radiator cap; — a fan with an electric motor and a thermal relay for turning on the fan; — thermostatic switch for overheating warning indicator; — flexible connecting hoses and clamps for their fastening.

The liquid-cooled Jupiter-5-03 engine has pistons, piston rings and a crankshaft that are not interchangeable with the air-cooled engine, along the hole in the upper connecting rod head, into which a special needle bearing is installed.

Antifreeze A40 M (TOSOL) is recommended as a coolant for IZ Jupiter-5-03. It is allowed to use water for a short time, preferably boiled, without allowing it to freeze. Using water in the system leads to premature wear of water pump parts.

Cooling system of the motorcycle IZH Jupiter-5-03 (IZH 6.113-03): 1 – thermal relay; 2 – fan with casing; 3 – collector assembly; 4 – supply hose; 5 – outlet pipe; 6 – carburetor; 7 – upper pipe of the chain cover; 8 – lower pipe of the chain cover; 9 – gearbox drain plug; 10 – flywheel hatch cover; 11 – flywheel hatch gasket; 12 – flywheel cavity plug; 13 – supply hose; 14 – mounting damper; 15 – hose clamp; 16 – radiator protection; 17 – radiator; 18 – plug.

The IZ Jupiter-5-03 cooling system operates in automatic mode, maintaining the liquid temperature within 80...90 degrees. During the warm-up period of a cold engine, the thermostat valves are closed, antifreeze circulates through a small hole in the manifold, having a limiting flow rate and flow rate. When heated to 80 degrees, the thermostat valve opens, reducing resistance to the flow of antifreeze, increasing the speed and thereby increasing the cooling efficiency.

The fan motor turns on at an antifreeze temperature of 92 degrees and turns off at a temperature of 87 degrees.

When the liquid is heated to a temperature of 98...104 degrees, the temperature sensor turns on the overheating indicator on the motorcycle instrument panel.

Safety valves in the radiator plug regulate excess pressure of 0.05 MPa and vacuum of 0.012 MPa.

The increased coefficient of volumetric expansion of antifreeze is compensated by an expansion tank connected by a tube to the radiator.

Coolant is poured into the radiator through the neck until the upper tubes are recessed (filling capacity 2.1 liters). Draining the fluid through the drain holes in the engine with the radiator cap removed.

Motorcyclist

The IZh Planet 5 motorcycle is originally called IZH “7.107”. This bike is a road motorcycle, which represents the middle class of sledding horses, and is intended for use on roads with different types of surfaces. This bike was produced at the Izhevsk Machine Building Plant starting in 1987. The 2008 edition of this series has been released.

The mover of the Fifth Planet can boast of seeing high thrust at low speeds. This model could be supplemented with a side vanity or passenger hood, with a boot. Everything is in the best traditions of wicked motorcycle life.

Often the IZh Planet 5 motorcycle is equipped with a trunk and knee guards. To reduce the pressure on the clutch, this bike is equipped with a multi-disc clutch, which consists of 7 pairs of discs. In addition, such an element of the engine was reinforced with splines of conductor disks simultaneously with the cam mechanism for connecting the coupling.

Another useful element of the fifth planet of the motorcycle is the presence of vibration dampers on the cylinder fins. The bike of this series is equipped with an air cleaner with a larger volume. An important feature is the presence of hydro-pneumatic suspension and disc linings for improved smoothness in motion.

Modernization of the motorcycle Izh Planet 5

Over the entire hour since the release of P'yat Planet Moto, various improvements and innovations have been added. There was a lot of modification of this Izhmoto bike.

The electrical system, for example, was reformed by installing a generator that runs on permanent magnets. The non-contact ignition system, which works independently of the rechargeable battery, has caught the heart of the buyer. They were intended to be installed and installed on older models of motorbikes.

An important additional motorcycle Izh Planeta 5 has been removed from the view of the automatically adjusted vibration of the fire. Also, the power unit of this Іж bike had a pump for the separate pneumatic system. This has simplified the operation of the oily horse, since now when refueling it is not necessary to add oil to the tank.

In addition, the Fifth Planet was equipped with a four-speed gearbox with an eccentric clutch engagement mechanism. Significantly strengthened the motor lance. The steering system on the front wheel was created in the form of a disc brake with a hydraulic drive. Dodatkovo worked on depreciation. The rear wheel suspension was supplemented with shock absorbers with improved characteristics.

Technical characteristics of the motorcycle IZh Planet 5

The fifth planet in Izhmoto is respected by the spiritual bikers. Without personalities, the Chinese motorcycle industry was born at that time.

The slimy horse has a small size. Its length is 2.2 meters, and the width is 0.8 m. The height of the bike reached 1.2 meters. In this case, the motorcycle has an average display of dry oil. Wine weighs in the region of 158-165 kg. Increased and maximum attention to the motorcycle body, equal to the previous Izhmoto models. Now Denmark is showing a weight of 170 kg. In this case, the trunk is ready to accommodate up to 20 kg.

The maximum speed recommended for the Izh Planet 5 motorcycle was a modest 120 km/year. The bike from Izhmash looks like it was very tight. The remaining figure is 22 horses.

P'yata Planet moto has a very large galmine road, which with a speed of 80 km/year reaches 42.6 m.

It attacks and vitrata fires. The most optimal fuel is at a speed of 90 km/h. However, at this speed, the fuel consumption will be 5 liters of gasoline per 100 km. way. For a single-cylinder motorcycle, that's a lot.

Bike engine

The Izh Planet 5 motorcycle is equipped with a two-stroke single-cylinder engine. The remaining diameter is set to 72 mm. The piston stroke reaches 85 mm. The power unit has the highest degree of compression - 8.7.

The motor of the Fifth Planet has a current working volume of 346 cm3. The vintage version has 4850 revolutions per hvilin.

The most pleasing thing, of course, are those bikes that are equipped with a separate engine replacement system. Their oil pump accurately doses the oil supply, depending on the rotation frequency of the crankshaft, as well as the demand for the power unit.

The Izh Planet 5 motorcycle is equipped with a K 65I carburetor.

Electrical equipment IZH Jupiter-5

The electrical equipment set of IZH Jupiter-5 and IZH Jupiter 5-03 remained unchanged, but the circuit and design of the devices were significantly improved. The connection of electrical devices is made with one wire, the other is the ground of the motorcycle. The wire goes along the plus of the power supply. The negative terminals of the devices are connected to the housing. The system voltage is 12 volts DC.

The price of a model can range from $100-500 depending on its technical condition.

The last notes

Technical characteristics of Izh Planet

To have a complete understanding of the capabilities of the first representative of Izhevsk motorcycles, let us turn to the technical characteristics of the Planet.

In various videos you can clearly see what tricks and inventions the owners of their motorized vehicles go to in order to make their two-wheeled horse better, more beautiful and more noticeable.

“The Planet Plays Sports”

Factory upgrades to the Izh Planet model were numerous. And of course, any model line is simply obliged to have in its ranks a unit of the “sport” class. Izh Sport is considered one of the most beautiful and fastest variations.

Sports class models have always been considered elite in the motorcycle industry. They received special attention, since they represented the possibilities of domestic production and received the best equipment. The sports motorcycle car was distinguished by grace and noticeable thinness, which is visible in the Izh Planet Sport photo and is very reminiscent of the Japanese type produced in the mid-twentieth century.

The front fender, which has an original mount, an interesting hub and a different version of the rear fender, paint before your eyes an image obtained by a mix of “Suzuki”, “Yamaha” and “Kawasaki Samurai”. The final distinctive touch was the color of the motorcycle: from yellow to orange with black details and nickel plating of individual elements, it caused quiet delight. Motorcycle enthusiasts, quickly appreciating all the delights of the new model, affectionately called it “dog”, from the abbreviation “Planet Sport” . To this day, being the owner of this motor vehicle is considered an honor and arouses universal respect among connoisseurs and bikers.

Technical characteristics of Izh Planet Sport

The first motorcycle variations received imported batteries for the accumulator. This continued until they mastered it and released model 6 MTS-9. Even the first characteristics of the Izh Planet Sport evoke respect for the manufacturer. It was impossible to remain indifferent to the rubber-cushion mounting of the engine on the frame, which was a real innovation. A one-inch difference in wheel sizes, Japanese electrical engineering - all this seemed unattainable.

Over time, Izhevsk carburetors brought improvements to the assembly. The latter, of course, had a smaller diffuser size and the generated power immediately dropped to 28 horses. Externally, they could be recognized by the elongated wing of the rear wheel and the arc shape of the exhaust pipe. These changes can be found in numerous videos from Izh Planet Sport.

Due to its high quality indicators, the Izh Planet Sport motorcycle was produced exclusively for export, and there was a scarce demand . The lucky owners of the high-speed unit have no choice but to improve their pet with their own hands. Amateur modifications directly concerned:

• boring of the M-412 piston (it was counterfeited to match the standard, or made similar to the piston 514 “Ceseta”);
• “twists” of the engine - they lighten the crankshaft due to milling;
• changes in bearings;
• for better lubrication, the crank chamber area receives a neighbor in the form of an oil seal with a bushing.

Reviews about Planet motorcycles are mostly positive. And for those negative aspects that are found in the configuration, there is always an amendment that everything can be repaired , remade or replaced. With good maintenance, this Soviet-quality motorcycle has no limit either in modifications or in service life.
