The Izh motorcycle is the most popular in Russia and the then USSR. One of the most popular was considered the IZH-Planet 5. This motorcycle began to be produced in 1987 and was produced for a little over 21 years. During this time, improvements and various changes were made. In 2008, the Izhevsk plant stopped producing Planet -5.
Izh "Planet-5" is a series of road or classic motorcycles of the middle class in weight, designed for movement on various types of road surfaces, as well as on light off-road conditions.
Bearing in mind almost all the main technical characteristics, Izh “Planet-5” is not much inferior to modern analogues. This vehicle was produced by Izhevsk Motorcycles OJSC (Izhevsk). The company is currently frozen indefinitely.
Supply and demand
Initially, the model was created in a single version; later, the design bureau developed a side trailer, which became an addition to the motorcycle. The new IZH Planeta-5 with a sidecar was produced in small batches, since customer demand was low. The main production was focused on the mass production of two-wheeled motorcycles. IZH Planet-5, whose technical characteristics were at the level of general consumer demand, was modernized many times. At the same time, the quality of the motorcycle increased, the exterior became more modern, and the service life of the units increased.
Transmission
Its characteristics are as follows:
- transmission of rotation to the clutch from the crankshaft - double-row chain;
- clutch - multi-disc in an oil-sealed ditch;
- Gearbox - three-shaft, four-speed, located in the engine crankcase;
- transmission of rotation to the rear wheel from the gearbox is a single-row chain.
The IZH Planet-5 engine is characterized by the following transmission ratios:
- crankshaft/clutch - 2.17;
- Gearbox/rear wheel - 2.33;
- first gear - 3.88;
- second gear - 2.01;
- third gear - 1.26;
- fourth gear - 1.0.

Load capacity
The IZH Planeta-5 motorcycle differs from other models in its class in that its engine has powerful traction at low speeds. This makes it possible to operate the machine in off-road conditions, when you have to move at a speed of 5-6 km/h. First gear ensures smooth running with low fuel consumption. Comfortable driving at low speeds is also facilitated by a 7-disc clutch with a cam engagement mechanism, which allows you to reduce engine speed to minimum values. Thus, “IZH Planet 5” will go where the engines of other motorcycles stall and they have to be transported by hand. The motorcyclist gets the opportunity to pass through an uneven section of the road with minimal losses.
The stable operation of the engine at low speeds also allows the IZH Planet-5 motorcycle to be used for transporting heavy loads. The side stroller can accommodate up to two hundred kilograms. Some craftsmen adapt an ordinary car semi-trailer, which is attached to the back of a motorcycle and becomes an additional means for transporting goods. IZH Planeta-5, whose characteristics meet the best standards of motor vehicles, is still successfully used in rural areas.

Conversion of Java electrical equipment 6V to 12V
Remaking the electrical equipment of Java Our magazine has repeatedly discussed the shortcomings of the power supply of the YAVA-634 motorcycle, produced before 1985.
At low crankshaft speeds (up to 1800 per minute), the 6-volt generator does not produce energy, and all consumers at this time are powered by the battery. If the lights and headlights are on, the battery is quickly discharged, which, with repeated cycles, leads to its failure. The only measure to avoid this trouble is to maintain medium speed even on bad roads or stops at intersections. It is clear that this causes great inconvenience, especially for residents of rural areas. The currently produced YABE model “638” uses a 12-volt electrical system (its description and diagram are given in No. 6, 1987), where a more advanced and powerful generator begins to work already at 1000 rpm. It is clear that many owners of the old model want to switch to new electrical equipment, but encounter an obstacle:... Read more >>
Motorcycles that are waiting. Future newcomers IZH Planet 2 and Jupiter 2
Future newcomers IZH Planet 2 and Jupiter 2 Hundreds of blue IZHs roll off the factory assembly line every day.
This motorcycle won't have long to wait either. A few more efforts and the car will come to life. Motorcycle enthusiasts are well aware of the IZH-Planet and IZH-Jupiter motorcycles. Our plant has been producing them since 1961 - 1962. And since that time, work has been continuously going on to improve them. The reliability of cars has increased significantly, and thanks to this, the warranty mileage of motorcycles has increased by 20 percent.

Motorcycles for mass sports. IZH-64M, Kovrovets 175S
For mass sports For many years, the domestic industry, along with road motorcycles, has been producing motorcycles for sports - cross-country and multi-day motorcycles.
The leading role in this matter belongs to the Kovrov and Izhevsk plants. The pioneers were Izhevsk residents, who built in 1947-1948. the first batch of IZH-350S vehicles. Since then, the plant has developed 24 models of sports motorcycles, which are supplied to sports clubs, motorcycle sections, and grassroots sports groups. The Izhevsk plant celebrated the year of the IV Summer Spartakiad of the Peoples of the USSR with the new serial sports model IZH-64, which replaced the IZH-60. Just like its predecessor, the new motorcycle is available in cross-country (IZH-64K) and multi-day (IZH-64M) versions. Fundamentally, its engine (cylinder size 72 X 85 mm, 346 cm3) has not changed. However, the new shape of the combustion chamber (“jockey cap”), the selection of the resistance of the exhaust pipes, and the reduction of the “harmful” volume of the crank chamber made it possible without changing the compression ratio (8.0&mdash...

Engine IZh Planet Sport. Tests
In the previous issue (February 1976) of the magazine, an article was published about editorial tests of the new motorcycle.
It mentioned that it was accepted by the editors in January of last year. And in August a message came from Izhevsk that instead of it you could get another machine from the factory, this time with separate lubrication. One of the authors of this article, B. DEMCHENKO, went to Izhevsk on an old motorcycle, and returned from there on another one, with separate lubrication. Below we publish travel notes about this trip, which was part of the editorial testing program, and material from engineers E. KONOPA and L. OVSIEVICH, based on the further operation of the IZH-Planet-Sport motorcycle. 5th of August. From Moscow to Kazan there are 800 kilometers of excellent road. They were completed without a single delay. The heat is about 28 degrees. The engine runs clean and quiet. But at speeds above 110 km/h, detonation appears, and when the ignition is turned off, glowing flashes are observed. However, there is no overheating or power loss. 6av... Read more >>

Noise reduction
At the very beginning of production, the new IZH Planet-5 motorcycle caused quite a lot of complaints about the high noise level. In this regard, it was necessary to modernize the engine. At medium and high speeds the piston skirt could be heard knocking. There was a need to increase the diameter of the piston by several microns so that it interacts more closely with the cylinder mirror. However, this method does not always pay off, since there is a danger of the engine jamming. Nevertheless, the design bureau took a risk, calculated the dimensions correctly, and the engine noise decreased significantly.
Sources of noise also lay in the chassis. The rear suspension, which is the most active part of any motorcycle, needed to seal the connection between the hydraulic shock absorbers and the pendulum fork. Special rubber silent blocks were installed to insulate the metal parts, resulting in reduced noise.
The muffler, which was originally direct-flow, raised quite a lot of questions. The exhaust rumble exceeded the permissible decibel limits. We had to radically change the design of the damper. The internal cavity of the muffler was equipped with mesh partitions, which significantly reduced the noise level.
Ignition
The production of the IZH Planeta-5 motorcycle began during the perestroika years. The USSR was experiencing changes that affected almost all sectors of the national economy. At the same time, the staff of the Izhevsk Machine-Building Plant tried in every possible way to maintain its production potential. Motorcycle production was expanding its base. The IZH Planet-5 model began to be equipped with a modern ignition system operating on an electronic basis. The contactless principle was new at that time, and many consumers were distrustful of the “know-how.” However, domestic motorcyclists soon became convinced of the reliability of the BESZ and the ease of maintenance of the electronic system. The main problem of the standard distributor-breaker, contact burning, is a thing of the past. The first motorcycle on the territory of the USSR, on which the most modern functional devices were installed, was considered the IZH Planet 5. Electronic operating principle ignition was one such device. However, some motorcycles were produced with outdated, but quite reliable contact breakers.
Wiring
The IZH Planeta-5 motorcycle is equipped with a standard set of incandescent lamps, switches and instruments. The 12-volt lamps are arranged in such a way that each can be replaced if necessary within a few minutes. The total number of light bulbs is 17 pieces, including:
- parking light bulb;
- high and low beam headlights;
- control lamp, responsible for the operation of the generator;
- speedometer indicator light;
- turn signal lamps on the motorcycle handlebars, rear fender and side trailer;
- side trailer marker lamp;
- trailer brake light;
- tail light lamp;
- motorcycle brake light lamp;
- high beam indicator light;
- light for monitoring the neutral position of the gearbox;
- turn signal indicator light;
- neutral signal light.
The electrical circuit of the motorcycle includes the following devices:
- generator;
- turn signal switch;
- brake light switch;
- fuse;
- neutral switch;
- ignition switch;
- sound signal;
- accumulator battery;
- turn signal switch;
- spark plug;
- ignition switch.
The electrical system includes a generator that powers an automatic non-contact ignition, independent of the battery. The IZH Planeta-5 motorcycle, whose wiring meets all safety requirements, is considered a good example of the rational use of electrical appliances.

"IZH Planet 5": repair and prevention
Motorcycles, like any road equipment, need maintenance and repair. The IZH Planet-5 model has a fairly long service life, but at the same time the machine requires preventive and sometimes major repairs. Routine maintenance of the motorcycle can be limited to timely lubrication of the hinge and sliding components, which include the rear suspension bushings, chain drive, accelerator handle and front brake lever.
The brake mechanisms themselves also need periodic cleaning. If the front wheel of the motorcycle is equipped with a disc brake, it must be disassembled and washed with a liquid cleaner such as Schnell-Reiniger or another product of a similar effect. As a rule, front disc brake maintenance is carried out when replacing the pads.
If the motorcycle has drum brakes, they also need to be periodically disassembled, cleaned and adjusted. This must be done at least once a year, and in the event of extraneous sounds during movement, knocking or friction, an inspection of the brake mechanism should be carried out immediately. The malfunction can be eliminated by adjusting the unit, and if the part breaks or becomes deformed, it must be replaced. It is unacceptable to ride a motorcycle with faulty brakes.
Design
The design of this bike was typically Soviet, in the best traditions of the domestic school of motorcycle building - a bulging round headlight, a flat seat, shock absorbers a la “candle”... But the gas tank visually raised up on the frame, the muffler pipes that went around the engine and shiny chrome wheels looked very good , like all of Planet 5 as a whole. The overall impression of the appearance of the motorcycle was somewhat spoiled by the cheap-looking turn signals and the pipes themselves, which, unlike the mufflers, for some reason they decided not to chrome, but simply paint them. Well, okay, in the USSR motorcycles were valued not for their external gloss, but for what they were capable of, and IZH is doing well with this.
Major renovation
A technical revision of the IZH Planet-5 model should be carried out as necessary:
- when the piston group wears out, when compression decreases and engine power drops;
- when extraneous noise appears in the gearbox;
- when the clutch “drives”.
Simultaneously with the overhaul of the motorcycle, you should carry out an inspection and preventive maintenance of all components and assemblies without exception, as well as touch up scratches and level out dents on the motorcycle body, if any.
If it is necessary to replace individual parts, they should only be replaced with new ones purchased in specialized stores. Spare parts for IZH Planet-5 are sold in a sufficient range.
Preventive motorcycle repairs can be done in a home workshop or garage. It is important that you have a set of necessary tools at hand, these are spanners and open-end wrenches, drifts, files and rasps, a vice, a drilling machine and a grinder.
Major repairs of a motorcycle, engine or gearbox are only possible in a specialized workshop equipped with all the necessary equipment, lathes and milling machines and a full set of metalworking tools.
If there is a need to replace a worn cylinder along with the piston, then you should purchase new parts in the original packaging, since in this case they will be matched in pairs and match the parameters. In this case, no adjustment is required.
Weaknesses of the IZH-P5 engine
- Air filter;
- Cylinder-piston group;
- Transmission.
More details about the weak points of the IZH-P5 power unit...
Air filter. To prevent dust from entering the engine, frequent washing and oiling of the filter element is required. Installing a paper filter would reduce the time spent on engine maintenance during maintenance and would improve the quality of cleaning the air supplying the carburetor.
The CPG wears out after 20,000-25,000 km due to the lack of water cooling.
Transmission. Over the years, due to wear and tear, the gears switch off on their own and adjustment does not eliminate the problem. In this case, it is necessary to overhaul the gearbox and replace worn out parts.
Resource
An important condition for the long-term operation of an engine that has undergone a major overhaul is proper running-in. The process consists of two stages - running the engine on a stand or on a stationary motorcycle; the second cycle is a test run in road conditions, on the move.
In both cases, the proportions of oil in the combustible mixture should be increased to 1:10, and the engine speed should be adjusted to the minimum. After 4 hours of running-in, you can increase the speed to medium, but make the process cyclical - after working for one hour, turn off the engine for 30 minutes, then start it again.
After a full break-in, the motorcycle should be maintained in a certain mode, avoiding overload and, most importantly, overheating of the engine. The machine must be operated for a certain period of time with only one driver, no passenger, no side trailer and no load. In this case, the final grinding of the cylinder/piston pair will occur.
400 kilometers is the optimal distance that a motorcycle should travel without a load, then it will be possible to reduce the amount of oil in the fuel mixture to a ratio of 1:25, and also operate the car with a side trailer.
