Ignition Izh Planet 5: features of setup and adjustment

Many motorcyclists, despite the enormous selection of modern motorcycle equipment offered by foreign companies, prefer Russian-made brands. One of the popular models of two-wheeled vehicles among domestic buyers to this day remains the IZH motorcycle, which was produced at the automobile plant in Izhevsk from 1987 until 2008.

The Izh Planet 5 motorcycle, the production of which took place during the years of perestroika, was intended primarily for use on hard road surfaces. The model was equipped with an electronic engine starting system. Therefore, for a long time, the motorcycle was in greatest demand among representatives of the middle income level. At the same time, some motorcycle equipment was manufactured with not quite modern contact breakers, due to which many owners of such “bikes” often encounter problems setting up the ignition of the Izh Planet 5 motorcycle.

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:

in position > – the generator sensor circuit is shorted to ground, which ensures the engine stops.
in position > (driving during the day) – the ignition circuit is turned on, the direction indicator circuit operates (when the direction indicator switch is on) and the brake signal circuit (when the brake pedal is pressed);
in position > (driving at night), two circuits are switched on:
a) a circuit of speedometer backlight lamps, license plate lighting and city driving (through a throttle, which serves as a device that complements the parametric control of the generator);
b) headlight lamp circuit A6-32+32 (via the light switch on the steering wheel).

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 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.

Ignition on IZ Planet. Tips for setting up.

Dear friends, please help me set up the ignition on P3. I've had my brains for about a week now. I've read a lot of smart and other books, but it still doesn't help. I do everything exactly as stated in the article from one forum given below, but the bike does not always start, sometimes when it works, failures appear, as if the spark has disappeared. but he manages to catch it himself. if the motor sits for about 20 minutes, then it is even more difficult to start it, it happens that it simply does not start, but shoots into the pipes (sometimes very loudly). I think the ignition is late. but by connecting the battery to 12V (the bike has 6V), it starts immediately. I have a couple more questions. The article says: “Before reaching the top point by 3.0 - 3.5 mm, the cams should open.” I did the same, looked at the light bulb. but it turns out that by unscrewing the base itself and turning it counterclockwise, the ignition turns out to be in the earliest position. There is simply nowhere to turn further. Please tell me how to fix this problem. I bought a new breaker yesterday. ps-generator on the bike is 6v, if that matters. THANKS IN ADVANCE .

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.

Rice. 11.3 – screws; 2 – eccentrics; 4 – breaker base; 5 – cam; 6 – rotor mounting bolt; 7 – stator fastening screw; 8 – terminal block; 9 – brush holder; 10 – capacitor.

We set the ignition on the Planet. We unscrew the generator cover or completely remove the right crankcase cover; personally, I prefer to remove it completely - it’s more convenient for me. Turn the crankshaft clockwise by the generator bolt until the breaker contacts are maximally open, loosen screw 1 (Fig. 1) and, turning the eccentric 2, set the gap between the contacts to 0.4...0.6 mm, tighten screw 1. Now, turning the crank shaft clockwise, set the piston to top dead center (TDC). Then, rotating the crankshaft counterclockwise, install the piston without bringing it to TDC by 3.0...3.5 mm. Having loosened the screws 3 by turning the base 4, establish the beginning of the opening of the contacts, fasten the screws. It is convenient to determine the beginning of the opening of the contacts using a probe. Connect one wire of the probe to ground, connect the second to the hammer terminal of the breaker, turn on the ignition, when the contacts open, the lamp will light up and this will begin to open the contacts. If you have a BSZ, then the point about setting the gap is naturally excluded, the moment of sparking is determined using the above-mentioned device or tester .Using a device: Install the device at the place of the switch, LED “D” should light up when the modulator is not in the DC (Hall Sensor) and go out when entering the DC, this will be the moment of sparking. If you don’t have a device, then you can get by with a tester. Set the tester to measure voltage (to a limit of 20 volts), connect it to the second and third contacts of the DC, the tester should show a voltage of about 7 volts when the modulator is not in the DC, and almost zero when the modulator is in the DC, the moment of transition from 7 V to 0 is the moment of sparking.

FORGET ABOUT THE BATTERY

Motorcycles of the Izh and Java brands can be quite easily converted to batteryless ignition. I did this seven years ago and still have no complaints. What is necessary? If the motorcycle has 6 V electrical equipment, then the 7 V generator set is from Minsk or the old Voskhod (with contact or electronic ignition); if at 12 V, then at 14 V - from the new “Voskhod”. Moreover, generator rotors can be either with removable or non-removable cams (in the first case, the installation procedure is simpler). For 2-cylinder engines (with electronic ignition), an additional sensor coil and another electronic switch will be required. Finally, the adapter flanges are turned from steel on a lathe and filed by hand, with a configuration depending on the brand of motorcycle.

The conversion sequence is as follows. First, the old generator with the relay-regulator and capacitors is dismantled, and the key is removed from the crankshaft.

Then a new generator is prepared for installation. To do this, it is somewhat modernized: the key is removed from the removable rotor cam (if it is left, the rotor will be installed as with a non-removable cam), and one of the mounting ears is cut off from the stator, since it will interfere with the crankcase protective cover. Thus, for example, in a Java with 6 V electrical equipment, the stator is attached to the flange with only two M5 bolts.

The generator stator of a 2-cylinder engine undergoes a more significant modernization: in order to place the second sensor coil, a special socket is cut out opposite the first (it is best to do this during adjustment).

Before assembly, for subsequent convenience of fixing the stator, the top dead center (TDC) of a single-cylinder or right-hand piston of a 2-cylinder engine is roughly determined and the adapter flange is attached to the crankcase.

On the crankshaft axle, if the crankcase protective cover fits snugly, place and center the rotor of the new generator while turning the crankshaft (the spark plugs are removed to make it easier). First tighten only the installed standard axle bolt to the end. To prevent the crankshaft from spinning at this moment, turn on the gearbox and jam the rear wheel (put, say, a hammer handle into the spokes).

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.

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:

place the motorcycle on the stand;
turn on neutral;
unscrew the spark plug from the cylinder;
remove the engine crankcase cover;

turn the crankshaft until the contacts are as open as possible;
using a screwdriver, loosen the locking screw;
using a special feeler gauge, set the gap to 0.35-0.45 mm and fix it with a screw;
we collect everything in reverse sequence;

turn on the ignition and start the engine. Its stable operation at idle indicates that the adjustment has been correctly performed.

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:

in wet weather, driving in the rain for a long time (oxidation or dampness of electrical contacts);
when traveling over rough terrain, replete with vegetation and bushes (mechanical damage to wiring);
when used in winter (snow and slush stick to the wires and can damage them).

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:

loosen the locknut using an open-end wrench;
turn on the ignition;
press the button to turn on the sound signal;
use a screwdriver to adjust the tone;
repeat the procedure until we get a clear and loud sound;
tighten the control nut.

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.

Step-by-step guide to installing and adjusting the ignition

To carry out the setup, you need to prepare a special tool, a tester, and a light bulb with two wires.
A caliper will be needed as a depth gauge. To set the gap it is convenient to use a special feeler gauge. Setting up SZ on IZ Jupiter 5 consists of the following steps:

First open the generator cover.
To make it more convenient to work, remove the right cover from the crankcase.
Using the generator bolt, turn the crankshaft clockwise. It is necessary to ensure that the breaker contacts open to the maximum distance.
Unscrew the screw a little and turn the eccentric. It is necessary to set a gap between the contacts equal to 0.4-0.6 mm. After this, tighten the screw well.
Rotate the crankshaft in the direction of movement of the clock hand. The piston should be installed at TDC.
You need to turn the crankshaft in the opposite direction, that is, counterclockwise. In this case, the piston should not reach TDC; a distance of approximately 3.0-3.5 mm should remain. By loosening the screws, you should establish the beginning of the contact closure. After this, the screws must be tightened tightly.
To determine if the contacts are open, use a test light with wires. One wire must be connected to the breaker hammer terminal, and the other to ground. After turning on the ignition, when the contacts are closed, the light should light up.
If BSZ is installed on IZ Jupiter, then there is no need to set the gap. To determine the moment you need to use a tester. The device should be set to measure voltage. The probes must be connected to the 2nd and 3rd contacts of the DC. While the modulator is not in the DC, the voltage reading on the tester should be 7 V. At the moment when the modulator is in the DC, the voltage reading should be in the range from 7 to 0 V. At this moment, a spark is formed.
The procedure must be performed on each cylinder. It is advisable to start adjusting the gap on the left breaker. When the left breaker is configured, you can move on to the right one.

Ignition adjustment, but let's start with a little introduction.

If now motorcycles from foreign manufacturers predominate on the roads, then literally 20-30 years ago only domestic Izh “Jupiter” and “Planet” rode on our roads. 2 years difference in production, identical appearance, there are not many differences in them, but still Jupiter-5 wins due to its two-cylinder engine and its easier starting.

Main components:

Two-stroke, two-cylinder 347.6 engine;
Air or liquid cooling system;
Automatic clutch release mechanism;
Drum brakes;
18 wheels;
The steering wheel has a conventional instrument panel (speedometer, ignition lamp, etc.);
Two shock absorbers. Setting up the ignition on Izh Jupiter 5 must be done in compliance with all rules. To do this, you need to know the exact algorithm of actions when carrying out this event. Therefore, in this article we will describe in detail how to set the ignition on Izh Jupiter-5.

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.

Having considered what the K-65 carburetor is, as well as its structure, you can adjust it in accordance with all the manufacturer’s requirements.

Wiring Problems

Practice shows that if the motorcycle was stored in a dry garage and was not subjected to dubious alterations, then the Jupiter 5 wiring diagram lasts a very long time. From time to time you need to change some consumables, such as lamps and ignition coils, but otherwise it functions quite stably. However, this is not always the case and problems do occur, for example:

wire breaks;
electrical circuit short-circuit;
failure of their individual branches of the circuit;
weak light from incandescent lamps;
incorrect operation of indicators;
misfire;
reduction in engine power;
complete failure of the system.

The problems described above can arise both due to natural wear and tear of wiring elements, and after incompetent intervention in the circuit. There is no universal solution to the problem in this case, and in order to find out what caused the breakdown, you should be patient and have some basic knowledge of the technical part of the motorcycle. First of all, you should get a multimeter or assemble a primitive network indicator using a 12-volt light bulb to “ring” the wiring for breaks. Having found a circuit node that is not working correctly or a wiring break, it will need to be eliminated, the network’s functionality re-checked, and so on, until operation is completely restored.

Setting up contact ignition on Izh Jupiter - 5

Let's take a step-by-step look at how to set up contact ignition on this device:

Align the piston of the desired cylinder: - insert a screwdriver into the cylinder - rotate the crankshaft while holding the screwdriver
Take a ruler and place it next to the screwdriver.
Rotate the crankshaft, holding the screwdriver down with your finger so that it is level. We find a dead point.
Turn the crankshaft in the opposite direction (1.5-2 mm).
A spark is generated when the cam opens, locate the two adjusting bolts.
Take a light bulb with two contacts, connect one to ground, the other to the contact.
Turn on the ignition switch.
You need to find the moment when the light comes on (the moment it lights up, the start occurs), and when it goes out, the contact closes on the contrary.
Turn off the ignition, do and adjust the same with the second cylinder

Ignition adjustment

First you need to determine which contact is used for which cylinder. Set the contact gaps to 0.4 millimeters; if the cam is very worn, reduce the gap to 0.3 millimeters. Next, unscrew the spark plugs and set the piston in one cylinder to top dead center. Insert any clean stick instead of a candle and make a mark. Measure 3 millimeters from this mark and align the piston to the new mark. Using a screwdriver, loosen the contact plate of this cylinder. Insert tissue paper between the contacts and turn the plate counter-clockwise until the paper can be pulled out. Instead of paper, you can connect a light bulb, one wire to ground, the second to contact. Rotate the plate until the light comes on. The second cylinder is adjusted in the same way as the first.

After all the procedures, all that remains is to add oil and gasoline, the motorcycle is ready for use. Correct wiring is the key to long and flawless operation of the Izh Jupiter 3.

Required Parts

In order for the ignition system to work correctly, a number of auxiliary parts are required. They are listed below:

Switch for BSZ VAZ cars. You should not choose exclusively from the low price segment. The Astro switch has a lot of positive reviews;
Hall Sensor. The best option for Jupiter 5 is a similar manufacturer VAZ. By purchasing it in branded packaging, you protect yourself from counterfeits;
Ignition coil with two terminals. You should choose between the gazelle engine number 406 or Oka with an electronic ignition system;
A pair of silicone armor wires with rubber caps;
The modulator is a butterfly-shaped plate made of iron.

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:

A stud with an applied thread of seven millimeters, pitch 1, as well as a pair of nuts with washers of the corresponding parameters. The priority material for these components is brass. This is explained by the least magnetization of the plate from the generator rotor. If you use a standard bolt, then difficulties may arise with the implementation of the ignition. The bolt tends to follow the modulator as it is tightened. However, it is necessary to observe the leading indicator, maintain the same position of the rotor and modulator, and tighten the bolt. It is advisable to use a pin, since many are not able to perform all the necessary actions in total;
A set of wires with connectors for ignition without contact from VAZ. This part can be purchased or made with your own hands.

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:

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.

Algorithm for adjusting the Izh Planeta-5 carburetor:

The first step is to check the fuel level in the float chamber. Unscrew the camera cover bolts with a screwdriver and remove it. Turn the carburetor over and use a ruler to measure the distance from the carburetor body to the top edge of the floats. It should be 26 ± 5 mm. If the parameters deviate, the tongue of the floats is bent in the appropriate direction using pliers. At the same time, in no case should the parallelism of the floats be disrupted.
Set a gap of 2 mm between the throttle valve and the bottom of the mixing chamber by adjusting screw 11. Then check the position of the throttle needle. The required needle position is the middle groove. The remaining grooves are made to move the needle lock and adjust the appropriate fuel quality depending on climatic conditions.
After all the above steps, we proceed to the most important stage - setting the idle speed. The idle quality adjusting screw 15 (located vertically on the left side of the carburetor) is screwed in until it stops, and then unscrewed 1-1.5 turns. Start the engine and warm up for 5 minutes. Using the mixture quantity adjustment screw 11 (located horizontally on the left side of the carburetor), we set the minimum stable engine speed. At the same time, slowly unscrew screw 15 until the engine speed stops increasing. It is the moment of reducing the crankshaft speed that will be optimal for determining the position of the adjusting screw 15. We again reduce the engine speed with screw 11 and unscrewing screw 15, we find a new optimal position of the throttle valve. This operation must be repeated until the minimum, but at the same time stable, engine crankshaft speed is established.
By sharply turning the throttle lever at idle, we check the correctness of the adjustment (the quality of the mixture). If, when the throttle is opened sharply, the engine stalls or picks up speed poorly, screw 15 needs to be tightened a little, thereby enriching the mixture. If the engine stalls when the throttle is closed, screw 15 should be unscrewed slightly.
You can also check the correctness of the adjustment by the color of the central insulator of the spark plug. After adjusting the carburetor, drive a motorcycle for a distance of 5-10 km and remove the spark plugs from the cylinder head. Dark carbon deposits indicate that the mixture is too rich. A light color (whitish or sandy) indicates that the mixture is poor. The normal recommended candle color is brown or brick.
It is also worth remembering that the free play of the throttle cable is 1-3 mm. If it is not there, the throttle adjustment will be incorrect. The free play is set by adjusting a special bolt located under cap 18.

Differences from the second Planet

For many modern citizens, the information that domestic motorcycle manufacturers worked tirelessly to improve their models in an era of total shortages may come as a surprise.

Note! The fact takes place, moreover, it is supported by official documents, in particular 1970N04P16-17 - this is the outgoing number of the factory newsletter, which described the changes made.

In the photo - official materials of the Izhmash Design Bureau

The new generation motorcycle received:

Direction indicator lights are a first in domestic practice;
Semiconductor relay for controlling direction indicators (installed in the headlight);
New size of wheels and tires (3.50x18 versus previous - 3.25x19);
New brand increased capacity battery (old one on IZH Planet 2 - ZMT-6);
And, of course, more engine power. The power unit now developed 18 hp.

Modifications

But the creator engineers did not stop there and, having released the five-millionth car from the production line, presented a modification of the IZH Planet 3-01.

Mirror and safety arches are the distinctive features of the new modification

Among the innovations it should be noted:

Rear passenger footrests;
Roll bars;
Rearview mirror;
New steering wheel design.

For reference: The buyer paid for the changes out of his own pocket. In particular, the price for IZH Planet 3-01 was 750 rubles, the version with a stroller was 1140, and the “rural version” was even more expensive. Fortunately, care instructions were included with purchase, which made maintenance easier.

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 of BSZ

Contactless ignition system - this element has become so popular that it rightfully occupies the place of the most popular improvement to the standard ignition circuit. From the factory, the IZ Jupiter 5 wiring model is equipped with a contact ignition system. It is unable to hold the ignition angle advance settings for a long time, has failures in operation and low accuracy. The disadvantages of this system can be listed for a very long time, so owners switch to electronic ignition, thereby increasing power, reducing consumption and getting a flat torque and power curve.

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.

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

When considering how to set up a K-65 carburetor, it is necessary to take into account a number of general recommendations. They must be performed before the process. All setup work must be carried out in accordance with the manufacturer's instructions. For owners of the presented vehicles who do not have experience in making adjustments, it is recommended that before starting work they carefully study all the requirements of the device creators.

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.
