Soviet motorcycles today are considered valuable transport, because back then they produced really high-quality and fast equipment. The Izh Jupiter 5 motorcycle is considered one of these legends of the USSR.
The Izhevsk plant produced several models, including Planet 5 and others. But Jupiter 5 was remembered primarily for its unpretentiousness on roads and maneuverability. With its small dimensions, the model was able to achieve low fuel consumption.

Instructions for assembling and disassembling the IZH Jupiter 5 engine
First, you need to understand the features of the motorcycle.
IZH Jupiter-5 is a vehicle designed for road travel with different surfaces. You can attach a stroller and a cargo module. The appearance of Jupiter-5 is distinguished by the strict classics inherent in the Soviet era, but at the same time it has its own individuality. The demand for this model lies in the small dimensions of the motorcycle, as well as decent power for that time. The engine of this motorcycle has two cylinders and two strokes. The cylinders are arranged in-line. The maximum developed power reaches 25 horses, which is 3 more than the single-cylinder IL Planet-5. This engine allows the motorcycle to move at a maximum speed of 120 km/h, while it has low fuel consumption.
The Izhevsk Machine-Building Plant began producing IZH Jupiter-5 in 1985, so spare parts are always available. However, the quality leaves much to be desired, which is why parts wear out quickly and the motorcycle requires fairly regular repairs. Sometimes, to find the cause of a breakdown, you have to disassemble half of what you didn’t even know about. Fortunately, in IZh everything is quite simple and the repair can be done at home. Repairing the IZ Jupiter 5 engine is not a difficult task, but if you are going to ride this motorcycle often, then you should not neglect to do the work correctly.
The main problems of Jupiter-5 include the current shock absorbers and cylinders, which alternately refuse to operate the engine. If you have encountered similar problems, then this article may help you in solving one of the annoying problems.
Main advantages
Motorcycles IZH Jupiter -5 were quite simple in design and did not require large maintenance costs. Today there are many who want to criticize this technique without regard to the times, but the model was in great demand among the population. She is not forgotten even now. On the secondary market only, on Avito websites, more than 2,000 units of equipment are offered for sale every day. The main reasons for its popularity are:
- Maintainability and simplicity of design.
- The presence of a semi-automatic clutch.
- Smooth ride, comfortable movement.
- Can be used with or without a side trailer.
- Good car dynamics without a side trailer.
- Durable welded tubular frame.
- Reliable and simple gearbox.
- Powerful alternator, good light.
- Confident engine starting in any weather conditions.
This is not an exhaustive list of the outstanding qualities of the machine.
The motorcycle has the highest level of maintainability. The shortage of spare parts of that time has given way to their abundance today. Any components can be purchased through online stores or in markets at affordable prices. With a small set of tools, a motorcycle of the simplest design can easily be rebuilt on the road. Replacing parts of the cylinder-piston group can be done without any problems directly in the field. More complex repairs involving removal and complete disassembly of the engine are possible in a garage without the involvement of large specialists or special tools.
The motorcycle is equipped with a semi-automatic clutch, which greatly facilitates the driver’s work. Gear shifting is possible without squeezing the clutch lever on the steering wheel. The clutch release mechanism is activated automatically when you press the gear shift foot. Before pressing the foot, it is advisable to release the gas - the switching will occur smoothly, without jerking the transmission. No other domestic motorcycle has such a system.
The machine is characterized by a smooth ride in single mode and with a side trailer. Riding a well-maintained motorcycle is a pleasure. The driver's position is comfortable and ergonomic. The passenger in the side trailer feels comfortable, protected from the flow of oncoming air and dust by a high transparent plastic reflector and a soft, durable awning made of leatherette. The trailer wheel has a spring-hydraulic shock absorber, which effectively absorbs uneven road surfaces.
A motorcycle with the index Izh Jupiter-5K-01 can be used with or without a side trailer. Operation of a motorcycle with a trailer is possible only if there is a corresponding mark in the technical passport when registering with the traffic police. When installing a trailer, the final drive gear ratio is changed by installing a smaller diameter drive sprocket with 16 teeth. At the same time, the engine traction force increases significantly due to an increase in the number of crankshaft revolutions. A 19-tooth drive sprocket is installed on a single motorcycle, increasing the speed capabilities of the motorcycle.
Without a side trailer, the machine has good dynamic capabilities. The two-cylinder engine quickly picks up speed and is capable of accelerating the car from a parking lot to 100 km/h in 12 seconds. This figure is 0.5-1.0 seconds better than that of the most advanced car at that time, the VAZ-2109, or the popular imported Java-350 motorcycle.
The motorcycle is assembled on a durable tubular frame, which is simply impossible to damage if used correctly. The side trailer has its own, no less durable frame, made of thick-walled steel pipes.
The gearbox is assembled in the same housing with the engine and has its own crankcase compartment. The unit is powerful, reliable, always working without problems throughout the entire service life of the motorcycle. There is an inspection hatch on the side cover of the clutch drive mechanism to check the oil level in the clutch housing and gearbox.
Electrical equipment operates from a powerful modern 12 V alternating current generator. Alternating current is converted to direct current by a diode bridge. All old problems associated with the operation of 6-volt DC generators installed on previous machines have been eliminated. The electrical system has become significantly more reliable. The headlight has halogen optics, which produces a fairly powerful stream of light.
The engine starts reliably at any time of the year due to the installation of an emergency start system that supports starting with a weakly charged battery.
How to disassemble the IZ Jupiter 5 engine
So, disassembling the IZ Jupiter 5 engine includes the following steps:
Now that you have looked at all the parts from the inside and found the problem, we replace the broken part. The easiest way is to look on the Internet at a spare parts sales site. You can also find it at a regular city market (flea market). Before assembling the IZH Jupiter 5 engine, carefully inspect its surface for chips, cracks, and wear again.
After you have thrown out the broken part and stuck a new, shiny one in its place, you need to return everything to the way it was. Assembling the IZ Jupiter 5 engine is a little more difficult than disassembling it. Everything is put together in reverse order.
As you can see, there is nothing complicated about this. It's another matter if you want to add a couple of horses to your pet. Then you will have to sweat a little, because tuning the IZ Jupiter engine will require a little patience from you.
Tuning the IZH Jupiter engine
Before you start, you need to decide how much power you would like to give to your engine. If you are quite satisfied with the average power, then you will need a ZiD-200 resonator. But if you want to make the IZH Jupiter 5 motorcycle fast and powerful, start tuning the engine by installing a resistor from the SMB-5 “motoblock”.
Replacing the air filter plays a big role in engine modification. The better the air is cleaned, the more horses the engine will be able to produce. After all, the degree of engine overheating depends on the amount of incoming air. It is best to use imported air filters. They provide improved cleaning and longer service life.
Next you should work hard on the injection system. An excellent option is to install a “Planet” carburetor with a diffuser diameter of 0.32 cm. Two carburetors will provide much greater acceleration and good dynamics. We take the flanges securing the cylinder from the standard tube, grind out the aluminum studs, and cut off the flange from the carburetor from the inlet tube from the Planet.
We grind the ends of the cylinder heads on a machine, and press the cylinders themselves. The maximum permissible volume of PIC is 18 cubic meters. see Install factory copper layers under the cylinder heads. And we adjust the ignition advance angle to increase compression.
We use the second flange from the old carburetor. Then we weld the parts using “cold” welding. And finally, we modify the assembly to be compatible with the inlet channels. all the cracks with epoxy liquid . Voskhod carburetors will provide uniform traction. In this simple way, you can add not only a couple of additional horses to your pet, but also provide more lively dynamics that give a good riding experience. The motorcycle is very reliable for everyday use, and if you take good care of it, breakdowns will occur very rarely.

IZH-1 - the first motorcycle of the Izhevsk Motorcycle Plant (9 photos)
On December 4, 1928, the first samples of domestic motorcycles, named Izh-1, came out of pilot production in Izhevsk (now OJSC Izhevsk Motorcycles).
See all photos in the gallery
At the end of the 20s, the Avtodor council sent P.V. Mozharov on a business trip to foreign factories. From there he brought several German motorcycles of different brands, instruments and tools.
Petr Vladimirovich Mozharov
At the same time, Avtodor purchased 14 well-proven English and American motorcycles, gave them bench tests and tested them (the then famous tester S.I. Karzinkin was involved in this matter) in the 1st All-Union Motorcycle Rally in 1928.
Leningrad engineers with L-300 (far right - Mozharov)
Mozharov, who took part in it on a German Neander, pleased the riders and spectators with the words: “... a Soviet motorcycle has already been designed, suitable for riding on our roads. Now the Izhevsk plant has started assembling such machines, by spring the first three prototypes will be ready, which we will probably present for the next motorcycle rally, and then Ruzhpultrest will begin their mass production.”
Indeed, in the fall of the same year, several experimental motorcycles began to be designed and built in Izhevsk. However, not everything went smoothly, and for the start of the 2nd All-Union Motor Ride, only IZH-1 was prepared (I. Shchedrin’s team of mechanics completed training on September 17, 1929), IZH-2 and IZH-3, and two more “IZH-4” and “IZH-5” were getting ready, but they were hopelessly late for the start.
So they were sent on the run untested, with unadjusted carburetors... Nevertheless, all five successfully completed the 3,300-kilometer route and finished in Moscow.” IZH-1 and IZH-2 were almost identical, equipped with four-stroke, two-cylinder, V-shaped engines with a displacement of 1200 cm3, maximum power of 24 hp. With. at 3000 rpm.
Magneto ignition. The engine was located across the frame. The gearbox had three stages. Drive to the rear wheel is by cardan shaft. The wheel of the side trailer (sidecar) was also driven, so the cars walked confidently off-road; 23 liters of fuel in the gas tank was enough for 300 km, the maximum speed reached 65 km/h. The front fork is parallelogram.
The motorcycle is based on a stamped frame made of two solid trusses. The lower part of the frame also served as a muffler housing - this feature was characteristic of all five motorcycles of the first series. It was an impressive car in terms of weight and dimensions with a two-cylinder four-stroke V-twin engine with a displacement of 1200 cubic meters. cm and maximum power of 24 hp.
The engine crankshaft was located longitudinally, torque was transmitted to the rear wheel from a three-speed gearbox, mounted in a block with the engine and driveshaft. The machine was intended for operation with both passenger and cargo trailers. The power reserve ensured the ability to drive on the most difficult roads.
Characteristic:
Engine displacement is 1200 cm3. Number of power strokes – 4. Number of cylinders – 2. Number of gears – 3. Reverse gear – cardan shaft. The fork is parallelogram. Wheelbase, mm – 1400 Ground clearance, mm – 120. Weight without side trailer, kg – 300.
The vehicle was intended for operation with both passenger and cargo trailers. The power reserve ensured the ability to drive on the most difficult roads.
Technical characteristics of the Izh Jupiter 5 motorcycle engine
Izhevsk motorcycle can certainly be considered one of the most elegant and reliable. Being very light and compact, this motorcycle is capable of carrying incredibly large loads. Thus, the IZ Jupiter 5 engine is capable of withstanding a load of 500 kg !
This is an excellent result. The motorcycle itself looks sporty. Classic minimalism of the Soviet period was intended more for the youth of that time, but was popular among all age groups.
Motorcycle appearance
When the Jupiter 5 model came out, its design was already well-known, because it was inherited from the Jupiter 4 motorcycle. But soon the Izh Planet 5 appeared on sale, and the developers saw that they could borrow several design elements.
The first modification had a square-shaped dashboard, which consisted of several indicators, an ignition switch and a speedometer. But soon its appearance was redesigned, and instead of one dashboard there were two. On the first part they placed warning lamps, and on the second part they decided to put a speedometer.
The design of the fuel tank has also been slightly redesigned, with rubber pads on the knees and the shape of the tank itself has become slightly different. Accordingly, in the new modifications of the Moto Izh Jupiter 5, it received a different, longer seat that ended at the brake light. This innovation is still considered stylish and modern.
During the Soviet era, creating high-quality and impressive equipment was as easy as shelling pears, because the country had all the resources for this. Thus, the Izhevsk plant produced a motorcycle that is capable of carrying a load of up to 500 kg. Just imagine what could be carried on this transport!
Being a workhorse, the motorcycle had a fairly sporty appearance and excellent top speed. With a power of 25 hp. the motorcycle could accelerate to 120 km/h. This is a completely standard indicator, because another representative of the Dnepr could give a maximum speed of 110 km/h. In severe frosts down to 30 degrees, the unit started up perfectly, which cannot be said about the current new products. Unfortunately, many owners complain of frequent engine breakdowns due to their long lifespan.
Main problems and their solutions
Disassembling the IZ Jupiter 5 engine, the video of which is presented below, is carried out not only as problems arise, but also for preventive purposes. For example, cleaning the carburetor is one of the conditions for maintaining stable engine operation.
The IZ Jupiter 5 engine diagram is simple even for inexperienced motorists. Therefore, during repairs there will be no difficult issues. In most cases, breakdowns occur due to the negligence of owners who improperly operate the moped and do not perform regular maintenance. For example, incorrect selection of oil for a particular time of year. So, if any part wears out, it must be replaced.
The engine is practical and very reliable
The engine turned out to be very reliable and practical. The simplicity of the system and unpretentiousness made it easier not only to repair, but also to operate the motor. Having 175 cc per cylinder, it not only pulled a side trailer loaded to nowhere, but also developed a crazy speed of 120 km/h at that time. Compared to heavy motorcycles, it even gained 10 kilometers in speed. It also performs well at low temperatures.
Engine diagnostics and repair
It is sometimes impossible to find the cause of a breakdown after one visual inspection. In some cases, complete disassembly of the IZH Jupiter 5 engine is necessary. But if you find out the reason, you can quickly solve the problem yourself. Here are examples of main faults and repair recommendations:
These are the main problems that may occur during operation. How to disassemble the IZ Jupiter 5 engine is written in detail in the maintenance book issued upon purchase. Everything stated in it is written in clear text, with diagrams and detailed instructions. Not only the repair of a Soviet unit is within the power of any owner.
There are many questions about how to assemble the IZH Jupiter 5 engine yourself, modifying it. For example, installing a more reliable carburetor or a more stylish and loud muffler can be done quickly enough without significant financial investments.
Tuning an IZH Jupiter engine with your own hands is possible if you have enough time and enthusiasm. You just need to be persistent.
The motorcycle has a favorable ratio of cost, build quality and maintenance requirements. An ideal option for people with a small budget and those who want to get universal equipment. However, frequent breakdowns will take a lot of time. It's worth being prepared for this, since some bikes can be 40-50 years old.

Instructions
1. Before starting assembly, clear the surfaces where the parts connect from any blockages. During each process, pay special attention to evenly tighten the mounting screws, avoiding distortions. Before pressing, thoroughly lubricate the bearings. Press the ball bearing into the right half of the crankcase, then install the installation ring into the left half. From the crank chamber side, press the oil seal into the crankcase, then install the second ring.
2. Insert the installation rings into the grooves of the crank chamber covers, press the ball bearings into them and put rubber sealing rings on them. Install the left crankshaft. At the same time, be careful not to damage the oil seal. Use a hammer and help to press in the crank chamber cover. After this, screw the screws and lock washers into it. The tightening force for these screws should be maximum.
3. Insert the crankshaft into the right half of the crankcase. In the same way, using a hammer and support, press in the crank chamber cover. After installing the oil seals on the crankshaft axle shafts and in the crank chamber covers, press them in. Next, insert the installation rings, press the ball bearing into the left half of the crankcase and secure the crank chamber cover with screws with maximum tightening.
4. On both halves of the crankcase, secure the screws securing the crank chamber covers to protect them from being unscrewed for no reason. Place a gasket and a cover with a crankshaft oil seal on the right half of the crankcase. Secure it with screws and cap it in the same way.
5. To assemble the cylinder-piston group of the engine, put the rings on the pistons with the help of plates. In this case, the plate locks must coincide with the piston pins. On the piston bosses, install a retaining ring in one of the grooves, and a piston pin, lubricated with machine oil, in the opposite groove. Place the piston on the upper head of the connecting rod so that the arrow points backward, and the piston ring locking pins forward in the direction of travel of the motorcycle.
6. Align the holes of the piston bosses and the bushings of the upper connecting rod head. Press in the piston pin with the support of the mandrel and hammer. Later, install the second retaining ring on the piston. In the same order, assemble and install the 2nd piston the engine Before installing the cylinder, check the connector planes. Clean these surfaces, install sealing gaskets on them, and place a wooden stand under the pistons. Lubricate the cylinder mirror with oil. Place the piston with pins on the cylinder and carefully fill the piston rings.
7. Remove the support from under the piston. While pushing the cylinder, place it in place and secure it. In this case, the ring locks do not have to fit into the cylinder windows. Correctly also put the 2nd cylinder in place, then install the carburetor pipe, gasket and head. Tighten the fastenings of the heads and pipe as follows: first tighten the middle screws until they stop, then the outer ones. Tighten the outer nuts evenly in a cross pattern.
Instructions for assembling and disassembling the IZH Jupiter 5 engine
The wiring diagram of IZH Planet 5 has a simple design: a single-wire DC network is provided by a 12-volt battery, which is charged by a generator with a power of 100–140 watts. The role of the negative wire in the electrical circuit is played by the metal frame, and since the rest of the wiring has a positive charge, their short circuit is often the main cause of the malfunction.

Generator
IZ Planet 5 generator design:
The generator converts the mechanical energy of a gasoline engine into electrical energy, which charges the battery. Alternating current is generated by 3 windings and fed to a rectifier, which converts it into direct current. An additional coil is used as an exciter.
Photo gallery: IZH Planet 5 generator and its design
Battery
To supply all components, a low-power energy storage device of 12 volts is required, since IZH Planet 5 does not have a starter. The purpose of a lead-acid battery is only to supply voltage to the ignition system and the excitation winding of the generator during startup.
Ignition system
In IZH Planet 5, the ignition coil converts low-voltage voltage into high-voltage and transmits it to the spark plug. That, in turn, is responsible for the spark that detonates the fuel. To ensure that detonation occurs only in the desired piston position, there is an ignition chopper.
From the factory, this model is equipped with a classic ignition system, which requires periodic cleaning of the breaker contacts and adjusting the gap between them.

Control devices
The following control devices are installed on the motorcycle:
Headlight and dashboard lamps
Conventional incandescent lamps are installed as lighting equipment and to illuminate the dashboard. Switching elements are responsible for supplying electricity from the battery to the lamps.
The headlight circuit includes lamps:
Switching elements
Switching elements are various types of switches that close or open an electrical circuit. They can be activated using keys on the dashboard (for example, turn signals) or by sensors.
In IZH Planet 5, the switching elements include:
Description of design
So, this motorcycle was first shown in 1971.
It was produced in two versions - “IZH Jupiter 3” and “IZH Jupiter 3K”.
They differed in that the “3K” was additionally equipped with a side stroller, but it had the ability to be detached from the motorcycle.
At that time, Jupiter 3 had a modern appearance and was well made, although it was based on its predecessor. All elements of the motorcycle were attached to a tubular frame.
To increase comfort, the front suspension travel was increased and the rear shock absorbers were made softer.
They changed the shape of the tank, it stopped being teardrop-shaped. But the headlight did not change; its housing continued to house the speedometer, ignition switch and warning lamps.
The seat is undivided, double. A rear fender with a brake light, turn signals and a license plate placed on it was attached to the seat body from below.
Turn signals on the IZH Jupiter family began to be installed precisely from the third model.
There were glove compartments under the seat on both sides of the motorcycle, the left one was intended for installing the battery, and the right one was for storing keys.
The engine was located under the tank, which ensured that fuel flowed into the carburetor by gravity. To prevent spontaneous leakage of gasoline, a tap was placed on the tank.
The cylinders had an in-line arrangement. When designing a new engine for this motorcycle, the position of the cylinder fins was revised, which subsequently ensured better cooling.
One elbow came out of each of the cylinders, to which two exhaust pipes were screwed, mounted on the sides of the motorcycle under the footpegs.
The power system consisted of a single carburetor located behind the cylinders and connected to them by a pipe with a double outlet. In the base, the motorcycle came with protective covers covering the carburetor.
By reworking the engine, the designers managed to increase its power by 6 hp, which affected the speed; it increased to 120 km/h.
The gearbox was made integral with the engine. Torque was transmitted via a multi-plate clutch. The drive to the rear wheel was carried out by a chain.
The rear drive sprocket was housed in an aluminum housing.
The front suspension was made in the form of a telescopic fork, and the rear suspension was a pendulum with two shock absorbers.
The brakes on both wheels are mechanically driven drums.
At one time, this motorcycle was awarded the State Quality Mark because it was reliable, easy to repair, and easy to start, compared to the IZH Planet.
Its only weak point was the contact ignition system. It practically consisted of two contact systems, one for each cylinder.
This affected the convenience of installing the ignition; it was difficult to achieve the same advance angle on the cylinders.
Required Parts
In order for the ignition system to work correctly, a number of auxiliary parts are required. They are listed below:
Modulator
The most difficult stage is the production of the modulator. It is important to maintain the required shape. The more accurately the required dimensions are observed, the lower the likelihood of problems occurring after the system is implemented, that is, there will be no need to adjust it with a file. The ignition timing must match on any cylinder used.
The bolt hole must be located in the middle. Otherwise, the engine operation will not be synchronized. It is also recommended to check the integrity of the crankshaft bearings. If you find defects, you should immediately replace it.
The contact ignition is not able to work normally if the bearings are damaged. The thickness of the part should not exceed one and a half millimeters. If it is thin, it will not be possible to avoid deformation, and if it is thick, it will come into contact with the surface of the hall sensor housing.
To create the plate, it is allowed to use any material except steel. Aluminum and others should not be used as they are not magnetic. The drawing that must be followed can be found in the public domain. The presented diagram will be useful to those people who decide to modernize the vehicle ignition device. Below are methods for installing electrical ignition devices in Jupiter.
It must be turned by a professional turner. He will make a simple disk and draw on it the markings of elementary distances between the corners. Then, in accordance with it, you will cut out the necessary sectors at home. The cost of the modulator is seventy rubles.
It is not advisable to use an ordinary plate, since its width is less than twelve millimeters. This will not be enough to fully accumulate the energy resource in the coil. Of course, it can be installed, but achieving four thousand revolutions per minute will become impossible.
In addition to the above you will need:
Final actions
You should put rubber caps on the armor wires, and insert the latter into the candlesticks or coil above. If you skip this step, the motorcycle will stall when riding in rainy weather, as moisture will get into the battery.
By inserting spark plugs into the tip, it will be possible to maintain excellent contact between the battery and the volume of the vehicle. Now you will need a pre-purchased set of wires. The switch, coil and hall sensor are connected by wiring. She needs to be isolated. Of the entire mass, only a common plus is required.
Maintenance
The owner can independently perform some maintenance procedures:
The need to inspect and adjust the wiring arises if:
Self-check of the Planet 5 motorcycle generator in case of loss of charge
The cause of loss of charge in the IZH Planet 5 battery is most often a breakdown of the generator.
To check it yourself you need:
Step-by-step instruction
The following steps must be followed:
The presence of a short circuit in the 3rd stage or a discrepancy in the indicators in the 4th will indicate problems with the generator.

Modernization
“Izh Jupiter” served as the beginning of a whole series of two-cylinder motorcycles:
- "Izh Jupiter-2" (1965-1971) - engine power 19 hp. at 4900 rpm
- “Izh Jupiter-3” (1971-1977) - power increased by almost 40 percent compared to its predecessor (25 hp at 5,700 rpm). The model was awarded the USSR State Quality Mark.
- "Izh Jupiter-3-01" (1977-1980) - engine power increased to 27 hp.
- "Izh Jupiter-3-02" (1979-1981)
- "Izh Jupiter-4" (1982-1985) - engine power increased to 28 hp. at 6,200 rpm, torque up to 3.58 kgf m, 12-volt electrical equipment, new lighting equipment.
- “Izh Jupiter-5” (IZH 6.113; IZH 6.114) (1985-1988) - engine power reduced to 24 hp. at 4800-5600 rpm, but the torque characteristics in the mid-speed range are improved. An “emergency start” button has appeared, which closes the generator excitation winding to ground, bypassing the voltage regulator, when starting with a dead battery.
- “IZH Jupiter-5-01” (IZH 6.113-01; IZH 6.114-01) (since 1988) - the motorcycle received a completely new appearance, unified with IZH Planet 5, released in 1987. The shape of elements such as the fuel tank, tool box lids, seat, and dashboard has been changed. Two cooling fins were added to the engine cylinders, nine instead of seven, the front part of each fin was bent towards the cooling air flow. A wide motor chain was installed, as a result of which the teeth of the motor sprocket and large clutch drum were changed.
- “Izh Jupiter-5-03” (Izh 6.113-03; IZh 6.114-03) (since 1993) - the model is equipped with a liquid-cooled engine IZH-Yu5 Sb. 1-08. Fuel consumption is reduced by 1.5-2 liters, noise level is reduced by 30%, engine power is 25 hp.
Electrical equipment IZH Planet 5
The motorcycle uses 12-volt electrical equipment. The electrical wiring of the IZH Planet 5 motorcycle is single-wire, the role of the negative wire is performed by a metal frame.
Among the main components are:
For reference: as is customary in auto and motorcycle construction, modification of components and assemblies allows you to reduce the cost of products. For consumers, the advantage is that the price is low and a number of parts are interchangeable.
Generator
The motorcycle is equipped with a three-phase alternating current generator with an electromagnetic excitation circuit.
The principle of its operation is as follows:
The instructions provided include the following items:
For reference: on three-phase generators of the IZH Planet 5 motorcycle, the windings are connected according to a “star” or “delta” circuit. The rectifier is installed as a separate unit, and the IZH Planet 5 electrical wiring is connected to it.
Headlight
Unlike European countries, where there is a requirement that motorcycles with permanent magnet generators must be equipped with a battery - since a motorcycle with a non-working engine must have side lights - there are no such restrictions in Russia (see also about the Ural motorcycle wiring diagram).
For reference: with such a generator, IZH Planet 5 did not need an external current source when starting the engine. Therefore, the battery was not included in the electrical equipment.
The head light circuit includes:
Control devices
The following control devices are installed on the motorcycle:
Design
The motorcycle retained the crew part of the Izh-56 motorcycle, but had a completely new engine - a two-cylinder, two-stroke, with a vertical transverse in-line arrangement of cylinders, air-cooled with a return-loop double-jet purge, with the preparation of the working mixture in the carburetor and its ignition in the cylinder from an electric sparks. The carburetor is closed with special casings (with a metal valve for access during start-up), the air filter is a contact oil filter. The parts of the connecting rod and piston group (piston, connecting rod, piston rings, piston pin, retaining rings, bearing rollers of the lower end of the connecting rod) are unified with the corresponding parts of the K-175 motorcycle engine.
The two-arm foot shift pedal and kickstart pedal are located on the left side of the gearbox housing. Izh-Jupiter, like all subsequent two-cylinder models, was equipped with an automatic clutch release mechanism.
The speedometer drive, unlike the Izh-56, is from the front wheel.
The front sprung mud shield is attached on a cast bracket to the lower bridge of the front fork, which eliminates the possibility of it becoming clogged with dirt.
