In any vehicle, ignition affects the overall performance of the engine. Moreover, if the settings are incorrect, starting the engine as a whole will be difficult. In this article we will talk about such legends of the domestic automobile industry as IZH motorcycles. How to correctly set the electronic ignition on the IZH Planet 5 motorcycle and what you will need for this - read below.

Izh planet 5 adjust the ignition
Izh Planet 5 is the brainchild of the Izhevsk Machine-Building Plant. Its production was discontinued in 2008, and the model itself entered the assembly line back in 1987. Accordingly, in any case, the bikes that are traveling on our roads are far from brand new. But they are reliable in service, so we will see this model on our roads for many more years. Izh Planet 5, the ignition adjustment of which is described below.
It goes without saying that with age, any technology develops certain problem areas. Izh Planet 5, in principle, does not create extremely problematic situations for its owner, but it does have a weak point - ignition.
In order to figure out how to adjust the ignition on Izh Planet 5 and be able to fix the problem yourself if necessary, you need to have a certain tool, time and a little optimism. The first time it may be a little difficult, but as they say, the master’s work is feared.
First you need to remove the crankcase cover, but you can get by by removing only the generator cover. In the first case, it will be more convenient to do subsequent work.
The tool you will need is a caliper or a feeler gauge, but in the absence of such, you can make an analogue of a depth gauge using a handy tool (screwdriver), the feeler gauge is needed to measure the gap.
We connect the control light to the terminal. We turn the spark plug out after turning on the ignition. We take the crankshaft by the generator bolt and turn it in the direction of movement of the clock hand until the moment when the breaker contacts are maximally open, after which you should loosen the screw, turn the eccentric and set the intercontact gap to approximately 0.5 mm.
Tighten the screw. We lower a caliper micrometer (or its equivalent) into the cylinder. Carefully turning the crankshaft, we find the top dead center (TDC) by performing rotations in the direction of movement of the hand on the clock. We fix or mark this position on a micrometer (screwdriver). Let's measure and record a 3.5 mm mark on the micrometer. below the original mark.
After which it is necessary to turn the crankshaft in the opposite direction until the piston stops with a micrometer (screwdriver, feeler gauge), while the piston should not cross the 3.5 mm line from top dead center (TDC).
Opening of contacts can be easily determined using a probe, one edge of which is connected to ground, and the other to the breaker hammer terminal. Turning on the ignition is accompanied by a light bulb, which indicates that the contacts have opened.
When you have neither a rod nor a probe at hand, try to trust your own eye, using available materials, move the eccentric with a wrench so that the contacts open as wide as possible. Loosen the screw securing the moving contact and use the eccentric screw to adjust the gap to 0.4 - 0.5 mm.
Find a 10 cm ruler that can fit into the spark plug hole, and rotate the armature with a wrench, gradually bringing the piston to TDC. Place a ruler against the piston, make a mark on it that coincides with the edge of the spark plug hole, and the next mark 3.5 mm higher than the previous one.
Rotate counterclockwise until the edges of the spark plug hole line up with the second mark. Lock it in. The ruler, of course, must be removed.
Now you need to place the spark plug on the ribs of the head , while loosening the two screws securing the contact pad, turning on the ignition, carefully move the pad from side to side to find the optimal position at which it will be possible for a spark to occur between the contacts and the spark plugs.
The site is fixed. We check the correctness of the adjustment - rotate the armature by the bolt, after turning on the ignition. A spark will appear at the moment when the piston is 3.5 mm from TDC. This was our second mark.
To prevent the engine from starting to work in the opposite direction after the piston rises to TDC, it is necessary to turn the crankshaft in the opposite direction until the piston is lowered below TDC by 2-3 mm. This procedure increases efficiency.
Today, many owners replace the standard ignition with electronic ignition on the Izh Planet 5. The installation of the BSZ on Izh Planet 5 can be carried out without dismantling the cam system, but it significantly improves all characteristics and facilitates operation. The road is waiting for you.

How to set the ignition on Izh Planeteka 5 without a micrometer
Setting the ignition
on a bike
IZh Planetka
3,
4
and 5 models.
To find the moment when the opening begins, use your light bulb. To do this, you need to connect the light bulb using a wire to ground, and connect the other wire to the terminal. Then you need to turn on the ignition of Planet 5. The engine should start when the contacts open: this will be indicated by a lit light bulb.
See:
Unscrew the bolts a little to set the ignition
on Planetka, you need to turn them all the way (also clockwise). The light bulb won't shine here. Then slowly turn the contacts in the opposite direction again until the light comes on again. At that time a spark should appear. So, of course, adjust the ignition of the Izh Planetka.
If your bike is equipped with a contactless engine starting system, then there is no need to set gaps, since the moment of spark formation is determined by using a special tester. Under such circumstances, to install the ignition on Izh Planetka 5, you must:
- correctly install the device to measure the voltage (up to 20 volts);
- connect the device to the 2nd and 3rd contacts of the Hall Sensor.
Ignition switch Voskhod - central switch
Switch 124005490201 is used as a central software switch that provides the necessary switching of lighting equipment on a motorcycle. The switch has three operating positions >, >, > in accordance with the following operating modes:
Caring for the central switch comes down to periodically checking the reliability of the switch in the headlight and cleaning the moving and fixed contacts from dust and dirt by washing them in gasoline.
the article I mentioned above:
First, we need to acquire (make, buy – underline as necessary) a special tool. 1) Tester (a 12-volt light bulb with two wires or a store-bought one) If you have a BSZ installed, then it’s better to use a device like this (you can buy it at a car store) or a tester. 2) we need a depth gauge - it can be a caliper, or a special device, personally I I use this PribludaVitalik offers this one. I think the meaning is clear. 3) Feeler gauges for measuring the gap.

The generator is good, but it needs to be rewound to 12V, otherwise the wiring will have to be redone a lot and the battery will not be able to be made into the lighting circuit; all the lamps except the neutral lamp and the 12V control lamp are easier to find than original ones. The faceplate was made according to drawings by Dmitry67:
The generator flywheel was not mounted as in the article, but as it should be - on a key. Of course, the rotor is 3 millimeters deeper than it should be, but everything works as it should
Article - “Does the Planet Need a Battery?” - have already been posted. This is right. It all started with this article for the majority of current users of such modifications.
However, there were earlier versions. I'll post one more to complete the collection. From the book of Boris Fedorovich Demchenko »
There are some mistakes there.
I converted several IZh motorcycles to Voshodov ignition (IZH 56, IZH P 3, IZH P 5, IZH PS, IZH Yu 3, IZH Yu 5.)
In the process of this work, optimized drawings of adapters were developed. The preferred material is alloy D 16. It does not rust - it is easy to process and holds the thread normally. If there are no suitable aluminum alloys, plain steel will do. The only negative is that it can rust. I don’t recommend stainless steel - it’s difficult to process it later on site. Drilling is also vicious. I tried to make one adapter from hot stainless steel - I did it but cursed everything.
Briefly speaking. The installation of the IZH generator 6 volt and 12 volt is different. Accordingly, different adapters are needed, depending on the motor model.
Drawings of blanks for a turner:
During manufacturing, it is advisable to sharpen the adapter from one installation. That is, at the end of processing it should be like a ready-made adapter - attached with the narrow end to the blank. And then they cut it off from the blank and trim the cut edge. This will create a part without compromising the wall thickness.
A little later there will be a continuation. This is not all I wanted to write yet.
Fuel level
Adjusting the K-65 carburetor begins with measuring the amount of gasoline in the tank of the float section. To do this, you will need to prepare a certain list of tools. Almost every home craftsman has them. The tool will be required during the process of dismantling the carburetor.
When the device is removed from the slots, you will need to remove the cover from it. It covers the float chamber. Next you need to take a ruler. The float has a special tongue. It needs to be unbent and bent to make adjustments. Due to this, the fuel level in the chamber will change.
You will need to place a ruler on the connector plane. Next, the tongue must be adjusted correctly. The strip on the float should be at 13 mm. The deviation is ±1.5 mm. The floats themselves must be level. The adjustment must be made very precisely. The operation of the carburetor depends on this.
Carburetor - removal and disassembly
It is possible to partially disassemble the carburetor (removing and washing the throttle, repairing the drive, etc.) without removing it from the engine.
1. Place the motorcycle on the center stand.
2. Remove the protective covers.
3. Shutting off the fuel supply, disconnect the fuel hose from the carburetor.
4. Use a screwdriver to loosen the clamp and disconnect the rubber air filter pipe from the carburetor.
5. 10 mm
Unscrew the mixture corrector nut.
6. Remove the corrector plunger assembly.
7. Disassemble the corrector plunger.
8. Pulling the cable sheath upward, unscrew the throttle valve cover.
9. Remove the throttle valve assembly. Cover the hole with a clean cloth.
10. To replace the cable, you need to compress the damper return spring, and, pushing the cable down, remove its end from the cut in the damper needle nut.
1. 12 mm
unscrew the two bolts securing the carburetor adapter pipe to the cylinder. We remove the carburetor with the pipe, being careful not to tear the paronite gasket.
2. Hold the bolts with a 12mm
, unscrew the nuts securing the adapter pipe
with a 13 mm
. We remove the pipe.
1. Using a screwdriver, unscrew the two screws securing the carburetor cover.
2. Remove the float chamber. There is a paper gasket underneath, be careful not to tear it.
3. Using a thin drift, carefully knock out the float axis.
4. Use thin pliers to remove the axle.
5. Remove the float along with the locking needle.
8 mm socket wrench
We turn out the seat of the shut-off valve.
7. Using a screwdriver, unscrew the jets of the main dosing system and the idle system.
8. 6 mm
turn out the additional jet.
9. 12 mm
We turn out the fuel-emulsion nozzle of the main dosing system.
10. Turn out the “quantity” and “quality” screws.
13. We wash all carburetor parts, except gaskets and rubber parts, in acetone or solvent for nitro paints. We clean all channels and jets with copper wire or toothpicks soaked in solvent, and blow them with compressed air from the compressor.
It is unacceptable to clean carburetor jets with steel wire, needles or any other tool.
We assemble the carburetor in the reverse order, while lubricating the rubber o-rings, threads and gaskets with engine oil or BSK brake fluid containing castor oil.
We tighten the “quantity” and “quality” screws until they stop. Then we unscrew the “quality” screw one turn (preset), and unscrew the “quantity” screw five to seven turns.
We check the operation of the shut-off valve. When the carburetor is oriented with the throttle channel down, the air supplied by the mouth into the inlet fitting should not pass through the valve.
Adjusting the position of the needle of the main dosing system is carried out by rearranging the lock washer in the grooves of the needle:
- washer to the left - enrichment of the mixture; - washer to the right - lean mixture.
Maintenance Features
Often during operation it is necessary to correctly set the gap between the contacts of the breaker. To do this, you need tools and a diagram to see which elements need to be dismantled.
The algorithm of actions is as follows:
In general, all the wiring of IZH Planet 5 is very easy to do with your own hands.
The need for such work often arises when operating a motorcycle:
Often the sound signal suffers during operation. Its malfunctions manifest themselves in the form of deterioration in sound quality.
To restore its functionality, you must perform the following procedure:
Conclusions: we are confident that this article will help you in servicing motorcycles of the IZH family (see also the article about). Both the attached diagrams and description will help you avoid making mistakes during operation.
While easily fixing mechanical failures, motorcyclists experience difficulties if the electrics fail. It’s completely in vain, the wiring diagram of the planet Izh 5 is not complicated, it’s easy to figure out.
There is no need to have special stands and equipment for repairs. A minimum knowledge of electrical engineering and a simple avometer (tester) is enough; even often you can get by with just a test lamp.
We will tell you in more detail about the main electrical wiring components and possible malfunctions. The Izh Planet wiring diagram makes it easy to find a broken wire or damaged insulation (for example, a bad contact always gets hot).
In this case, we look to see if there is a spark at the coil output and at the output at the spark plug contact. Let's take a closer look at the main wiring components of the Izh Planet.
Motorcycle service
Unlike other models, both domestic and foreign, IZH Jupiter 3 is distinguished by enviable survivability.
Here are a few instructions for resuscitating a motorcycle that has stood motionless:
- It is enough to replace or clean the candles yourself;
- Adjust the ignition;
- Replace high-voltage wires from the coils with spark plugs;
- Change the engine oil;
- Install a new battery or charge the existing one.
Modern scheme, more understandable to the younger generation
And it will start and drive. And this is its distinctive feature, which is well known to the generation of the 80s. You can restore the old paintwork, reupholster the seat, or polish the chrome parts to a shine later, the main thing is its durability.
Advice: wiring IZ Jupiter 3 after long-term storage also requires close attention. Inspect it for abrasions and damage to the insulation. If any, replace the wires. Do not repair, but replace.
In the photo - the restored IZ Jupiter 3 (right) looks no worse than modern models
In the video below you can get acquainted with the features of this model. It should be noted that the cost of restoration is quite affordable for most, and the difficulty lies only in the lack of spare parts and the need to modify those found from other models.
Dosage system
The K-65 carburetor is adjusted especially carefully in the area of the metering needle. Its position must be carefully adjusted. The engine must be well warmed up. If it has already cooled down, you need to ride the motorcycle for some time on the highway.
On a straight section of the route, you can evaluate the engine's performance. If turning the throttle does not have sufficient effect, you will need to raise the needle. This will lead to an increase in gasoline in the fuel mixture. If after the next trip carbon deposits appear on the spark plugs, you will need to lower the throttle needle one notch.
This approach will ensure stable operation of the engine at medium speeds. This is the most frequently used mode when operating motorcycles. The maximum speed allows you to adjust the measurement of the jet cross-section. When the throttle is turned all the way, it will ensure the operation of the system.
Improving the standard system
The ignition system can be improved in other ways. To do this, you need to identify what problems there are with the wiring. They can occur in the primary circuit between the coil and the 12V battery or due to operating conditions. A visual inspection of the primary circuit can reveal problems with connections, contacts and the ignition switch.
But when dirt and dust get into the circuit, the resistance at the contact points increases, which entails a decrease in voltage from 12 Volts to 7-8 Volts. This voltage is not enough for a powerful discharge to appear in the secondary winding of the coil. As a result, a charge of less than 12 V appears on the spark plug, which poorly ignites the combustible mixture in the cylinders. Burnt contacts, oily spark plugs and batteries with a charge of less than 12 V further worsen sparking.
The following measures help solve these problems:
- The plug connectors are removed and each wire is soldered using traditional soldering and then insulated.
- An additional toggle switch is installed that turns off all consumers when the engine starts. Thus, the coils are supplied with 12 volt voltage from the battery (diagram 1).
- Remake the ignition switch (IZ) (diagram 2). You need to take a wire and solder one end of it to the connector of lock 4, which is free, and the other to the positive terminal of the coil. The standard wire should be re-soldered from terminal 5 to terminal 6. After turning on this position of the key, power is supplied from the battery to the primary circuit according to a simplified scheme.
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 reliably the required dimensions are observed, the lower the likelihood of problems occurring after implementing the system, that is, there will be no need to adjust it using 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:
Setting the appropriate options
Setting up the BSZ on Izh Jupiter 5 also requires special attention. The ignition is turned on with the tachometer connected. After thirty seconds, indicators of 3000, 4000, 5000 rpm should appear on the device panel. If they are present, then the switch is working correctly.
In other cases, you should pay attention to previously grounded candles. We insert a screwdriver into the hall connector, and then pull it out
A spark should appear on the spark plugs. If it was not possible to cause a spark using the steps described above, then the reason for the incorrect operation is incorrect connections.
The setup looks like this. The dial indicator is unscrewed and the cylinder piston is adjusted. Having connected the voltmeter to the second and third connectors, you need to start rotating the modulator axis. After a jump from 7 to 0.1 volts is detected, the modulator must be secured with a nut. Usually the required advance angle is set.
The test run should be successful if you install the components yourself according to the instructions. Now you can use BSZ.
The main problem with the Izh Jupiter motorcycle engine is the standard contact ignition system. Any owner of Jupiter sooner or later faces the problem of failure of one of the cylinders due to a change in the gap in the contacts or failure of the capacitor. Adjustment helps, but usually not for long. This problem can be radically solved by installing a contactless ignition system on a motorcycle.
Single-channel BSZ.
There are probably many options for BSZ design, but we won’t consider them all. Let's focus on the simplest, and probably the most common option in our country. There is no motorcycle market or motorcycle store nearby where you can buy a factory-made BSZ, and there is no turner with a machine nearby either. We will proceed from this.
Minimum set for installation
But we can’t do without a minimum set, so before you start work, you need to stock up on the following components, which are sold in any auto shop or car market in our country:
- Ignition circuit Izh Planet 4 12 volts. Izh Planet bike of the fifth model: what should you know about its wiring? explanations for the diagram
1. Switch from VAZ 2108
2. Hall sensor from VAZ 2108
3. Set of wires for BSZ from VAZ 2107 (from distributor (Hall sensor) to switch)
4. Two-terminal ignition coil (from an Oka or Gazelle car with a ZMZ 406 engine)
5. Two automotive silicone high-voltage wires of the required length with caps for spark plugs (you can buy a kit for a VAZ and take it from there, you can simply find used wires, after first making sure they are working)
Next, in addition to the components, we will need a small flat piece of sheet steel 1-1.2 mm thick to make a modulator and a plate for the Hall sensor. I warn you right away that stainless steel or non-ferrous metals are not suitable for the manufacture of the modulator, since they are not magnetic materials. To make a plate for the Hall sensor, you can use any material of sufficient strength.
Tools you may need are a drill with drills, files, a chisel, a hammer and other tools that, as a rule, are found in any garage.
Rework process
We dismantle the old ignition system. We remove the plate with contacts, capacitors, ignition coils with high-voltage wires from the motorcycle. We install the switch in the right glove compartment.
We attach the ignition coil to the frame under the tank. We connect the wiring connector to the switch, connect the black ground wire from the connector to ground. We connect the wire from terminal No. 1 of the switch connector to one of the coil terminals. We connect the second terminal of the coil to the old wiring, to the wire to which “+12V” is supplied when the ignition is turned on. In the old wiring, this wire connected both ignition coils. From it we pull an additional “+12V” wire to the switch, which we connect to the 4th wire in the connector. We carefully isolate everything. We insert the wire with the connector to the Hall sensor into the cavity of the generator.
You can check the functionality of the system. We connect the Hall sensor to its connector, connect the high-voltage wires to the coil and to the spark plugs. We provide reliable weight to the candles. Turn on the ignition and pass a metal object (you can use a flat screwdriver) through the Hall sensor slot. The spark plugs should spark. The scheme is working. (If there is no spark, then something is connected incorrectly and everything needs to be checked again.) Now it remains to supply a spark at the right time to the cylinders, for this:
Adjusting the K-68 carburetor on the IZH Planet-5 motorcycle
The K-68I carburetor was installed on the Izh Planet-5 motorcycle more often than others. With proper setup and proper care, the motorcycle starts quickly, runs smoothly and without complaints.
To adjust the K-68I carburetor you will need a flat-head screwdriver, pliers, and a ruler. For clarity and ease of adjustment, use the K-68 carburetor diagram.

Electronic ignition for the IZH PLANET 5 motorcycle
Generator Izh Planet 5 on permanent magnets, with a contact ignition system that operates independently of the battery, with automatically adjustable ignition timing. Therefore, on Izh Planet 5, electronic ignition can be installed from a VAZ 2108. Installation takes about two evenings. In a nutshell:
1. Manufacturing and installation of a corner
(Fig. 1) for attaching the Hall sensor (the standard contact ignition was not touched!) into the standard threaded holes on the generator platform (photo. 2). Both elements are made of ordinary iron with a thickness of 1.5 mm.
3. Installing the reel under the tank
(photo 3). There is not enough space, but it can be installed. I had to cut out the fastening sleeve.
4. Mounting the Switch
(photo 4). I turned and turned for a long time, and found a place only near the signal, under the tank.
5. Wiring
(photo. 5). Nothing complicated, except for pulling the casing with wires from the Hall sensor under the clutch cover.
6. Connecting all the elements
according to the diagram (Fig. 6).
Set the ignition timing to 3.5 mm before TDC. It is worth considering that the sensor produces a pulse when the modulator exits the gap. Start the engine. If everything went well, then you can safely drive, having a contact ignition system as a backup. Everything went smoothly for me. The start was easy and there were no problems. When the engine was warm, the speed was stable, and the engine responded perfectly to the accelerator handle.
Ignition timing former (FUOZ)
I ask the skeptics to calm down, FUOZ is working and, in all likelihood, will be put into production. There will be one manufacturing option for 1 and 2 cylinder engines. A new feature has been added - individual settings for a specific engine. Those. the characteristic will be set by the driver himself, right on the go. Moreover, the established characteristic will be remembered and used in the future. The algorithm is simple: 1) start the engine; 2) let it reach operating temperature; 3) start moving; 4) having fixed the throttle handle in a certain position, adjust the OZ using the FUOZ potentiometer; 5) press the “remember” button 6) repeat step 4. for other speeds. Because such templates may be a lot, then for a loaded motorcycle you can build another characteristic and switch to it via the menu item. It is possible to switch between m/s templates when the specified temperature is reached, which will also be very useful. This way you will get an almost ideal performance for your engine.
FUOZ is a device for forming the required ignition timing of a motorcycle (and not only a motorcycle) with extended service functions. The device is surface mounted and fits under the LCD (PC1601LRS-FNH-B/PC1601F D). FUOZ is connected to the gap of the Hall sensor (control output of the DC) and 6 con. switch. The OZ schedule is shown in the figure. The graph is taken from a similar device, which is made on an ATMEL microcontroller and runs 100% on IZ Jupiter 5.
If desired, set the characteristic for a specific engine independently, according to the algorithm above. The choice of characteristic is displayed on the LCD. The ideal option, of course, is a knock sensor + throttle position sensor + air flow sensor + temperature sensor + injector
The device can be made without an LCD, for simplicity. In this case, the visibility of the device’s operation is lost, and it is more difficult to adjust some parameters.
The initial SOP is set to about 30 degrees (7 mm before TDC). FUOZ ensures the production of the required delay with high accuracy. At minimum speeds, the pulse delay will be maximum (SOP is 0 degrees), and at high speeds, vice versa (SOP tends to 30 degrees).
The FUOZ diagram for the option with LCD is shown in Fig. 9. The FUOZ is made on a PIC controller MicroChip PIC16F873, operating at a frequency of 4 MHz. The circuit is simple and does not require any explanation; the parts are surface-mounted (except for the LCD).
Here are drawings of a (test!) double-sided surface mount printed circuit board measuring 84x57mm.
All this fits into the dashboard of a motorcycle.
The main menu item displays: engine speed, SOP, on-board network voltage Temperature, octane correction angle Multi-spark mode (Options: On/Off). If “On”, then at revolutions less than 400 it produces three sparks. Indication of overtemperature (Options: Off/100/120/140/160) Indication of overspeed (Options: Off/4000/5000/6000) Backlight (Options: On/Off ) UOZ mode (Options: Pattern #1 / Pattern #2 / Pattern #3) Switching between patterns when the set temperature is exceeded
Installation and configuration instructions
In IZH Planet motorcycles, be it version 3, 4 or 5, the ignition installation in accordance with the diagram must be carried out using the device that came with the motorcycle.
But since it is not so easy to find this device today, we will make do with improvised means. Non-contact ignition is configured by adjusting and setting the gap of the distributor contacts. An equally important nuance is the correct setting of the moment of sparking. Diagram and designation of parts of the IZH distributor
If your IZH Planet 3 is equipped with a single-cylinder internal combustion engine with a G-36 M generator device, then in this case the procedure for setting the gap is carried out by turning the eccentric, marked in the diagram with the number 1. In this case, bolt 2 according to the diagram must be loosened, and the eccentric itself is turned or right or left. Before setting the BSZ on products from the IZHMASH plant, the crankshaft must be turned. It rotates until the moment of greatest divergence of contacts occurs. It is in this position that the ignition of the IZH Planet 5 is adjusted - you need to ensure that the maximum gap on the contacts is around 0.35-0.45 mm.
According to experts, the ignition system should be adjusted with the cylinder head removed. In this case, the piston itself must be located in a position where it does not reach the dead center; to find out what the clearance should be in this case, you need to use the instruction book. For example, in versions 3 this parameter should be 3.5-4 mm, in Planets 4 - from 3 to 3.5 mm, and in Sports versions - from 3.5 to 3.8 mm. It is in this position that the spark will appear. The adjustment procedure in this case is performed by turning the interrupter assembly, while the bolts marked in the diagram as number 10 must be loosened.
Assembly diagram for IL
, in particular, setting the gaps between the contacts of the interrupting device should be done in the following order:
- First of all, the crankshaft is turned by the kick starter.
- One of the interrupting elements is set to the contact opening position. In this case, the bolt marked number 4 in the diagram must be loosened.
- Next, using the eccentric number 3, the gap is set; this figure should be from 0.4 to 0.6 mm. After this, the same actions are carried out with the second pair of contacts.
It should be noted that the entire procedure must be carried out with the candles unscrewed. When you place the dipstick in the corresponding hole for the spark plug in the right cylinder, you need to turn the crankshaft with the kick starter. You need to find the top dead center and having found it, you should make several marks on the dipstick - one of the marks should be placed at the level of the hole, and the other should be located slightly higher - about 2-3 mm. After this, the crankshaft must continue to be turned, this is done until the upper mark reaches the position in which the first mark at top dead center was set (video author - Garage in the USSR).

In this position, the elements of the interrupter assembly, which is located on the lower surface, will begin to open. It should be noted that the procedure for setting the contact opening is done by turning the base, but to do this you need to loosen the bolts numbered 2 and 7. And when you can make the adjustment correctly, these screws will need to be tightened. As for directly determining the moment of rupture, it can be detected thanks to a light bulb, which must be connected in advance to the body ground and the distributor terminal.
After the torque on the right cylinder has been set, the same procedure is performed in a similar way only on the left cylinder. In general, the situation is similar, only in this case it is not the lower, but the upper base that rotates, and in this case, bolts 1 and 7 should be loosened.
Main stage
As noted in the assembly diagram of the Izh-Planet 5 box, further disassembly operations are carried out above the insides of the roof of the unit, since the secondary shaft and sector could remain in it. If it is necessary to remove them, you need to straighten the petals of the lock washer, unscrew the nut, remove the star and washer. Holding the gear very carefully to prevent the shaft from jumping out, the cover is moved to a clean and flat surface with the gear facing up.
It is worth noting that the bearing of this part of the assembly does not have a retaining ring. Therefore, when removing the shaft with bearing, the rollers may fall out, so be careful. If the specified element has exhausted a decent service life, there is a risk that when dismantling the secondary shaft, the outer ring may jump out of the seat and remain on the rollers. Next you need to start pressing out the oil seal. To do this, the installation rings are removed from the hole in the cover, after which the outer ring of the bearing is removed.
Model features
Therefore, even today, enthusiasts retrieve famous motorcycles from dusty sheds and garages, restore them to their original form and, as before, give the spirit of freedom to their owners.

What is especially pleasing is the interest of modern youth in domestic technology. This article is intended for them and their parents who had the opportunity to ride Izhaks, Jupiters and Planets .
Electrical diagram
The IZH Jupiter 3 model appeared as an improved example of the previously produced IZH Jupiter 2. For the first time in domestic practice, a motorcycle received turn signals, and therefore the wiring diagram of the IZH Jupiter 3 has undergone changes.
In particular:
- There was a separate cable running under the gas tank and seat to the rear turn signals;
- For the model with a side trailer, a second cable was laid and attached to the stroller frame.
The new model is based on the proven electrical circuit of its predecessor.
The photo above also shows the wiring on the IZ Jupiter 3 in the version with a sidecar.
They asked from her:
- Lamp (yellow) for trailer brake lights (indicated as 2a in the diagram);
- Lamp (red) for the rear marker light of a trailer (3a);
- Right direction indicator on the trailer fender (11);
- Trailer front marker light (white) (17).
One can argue for a long time about the quality of products of the domestic motorcycle industry, but a motorcycle in capable hands required only preventive maintenance and adjustment. And the era of shortages forced owners to show miracles of ingenuity, modifying unreliable components and assemblies of their two-wheeled horses.
For reference: Izh Jupiter 3 deservedly received the Quality Mark. This was evidenced by a sign on the frame - in the photo below. Today, finding such a motorcycle without “crooked” improvements is a great success for collectors.
Self-improvement
Many were not satisfied with the capricious ignition of the motorcycle (see the article wiring diagram for IZH Planet 3), so the wiring diagram for IZH Jupiter 3 was often changed from 6 to 12 volt. This was facilitated by the appearance of the 281.3701 generator produced by the Izhevsk Motor Plant, which was much better and more reliable than the standard G36M7. Those owners who were not able to get it had to upgrade the existing one.
For this:
- A steel adapter plate was machined, allowing 12 internals to be installed in the generator;
- The right engine cover was purchased or exchanged from older models Jupiter 5 or Planet 5.

In what cases is ignition adjustment necessary?
During the operation of the vehicle, the owner faces many problems. The most serious failure is related to the engine. In order to spend significant funds on major repairs, it is necessary to monitor the technical condition of the motorcycle and carry out preventive work, including adjusting the valves and valves (video author - Hana Rulyu).
If you do not monitor the SZ, then the motorcycle engine may not reveal its full potential and will not work at full capacity. This can lead to a reduction in its service life. An ignition adjustment is necessary if the engine is running poorly, the muffler or carburetor is firing. True, before setting up the SZ, you should make sure that the cause of the malfunction is in it.
It happens that the flywheel bolt, which connects the two halves of the crankshaft, comes loose, begins to play and does not work well. Sometimes he even cuts the key.
Setting up the SZ may be necessary after repairing lock 5. The installation and connection itself are carried out according to the diagram.

General recommendations
The carburetor must be in good working order. If there is any abnormality in its system operation, it is necessary to carry out system maintenance.
If necessary, the system will need to be thoroughly cleaned. All consumables are replaced with new seals. The air filter must be clean. If necessary, it must be washed. In some cases it will need to be completely replaced.
When adjusting the carburetor, the engine must be warm. To do this, you can drive several kilometers along the highway. Only after this can you begin the procedure described below.
