Izh Jupiter-2 - road bike middle class, designed for driving on roads with different surfaces. Produced by the Izhevsk Machine-Building Plant. It was a continuation of the Izh Jupiter series of motorcycles, produced from 1971 to 1971. Then the engineers were faced with the task of making a new motorcycle with a two-cylinder engine. They succeeded.
The motorcycle turned out to be quite powerful (19 hp), the engine displacement of the motorcycle was 347 cm³. The battery was alkaline at 6V.
Izh Jupiter-2 was well received by motorists, but then the opinion changed. The reason for this was the technical problems that arose in operation, in particular, on a motorcycle, the ignition angle constantly went astray over time, due to the negligence of crooked craftsmen who forgot to install engravers. The design of the motorcycle turned out to be not entirely successful: the main and glaring mistake of the designers is that on the gas tank, where the Izh badge usually stands, there was a badge with a painted planet similar to Saturn, but not Jupiter.

Hundreds of blue IZHs leave the factory assembly line every day. This bike is also not long to wait. 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 the machines has increased significantly, and thanks to this, the warranty mileage of motorcycles has been increased by 20 percent.
Factory designers are working not only to eliminate the flaws identified during operation, to improve the model on the conveyor. Our design bureau also prepared new, modernized models of motorcycles, paying special attention to such qualities as reliability and durability. Now all work on the creation and testing of new machines has been completed. "IZH-Planet-2" and "IZH-Jupiter-2" are ready for launch.
How do they differ from their well-known predecessors?
The first thing that catches your eye - appearance. New machines are more in line with the requirements of modern technical aesthetics. Motorcycles are painted in a single, corporate color. The wheel rims, muffler housings are covered with a layer of decorative chrome plating, and the protective covers of carburetors and brake covers are covered with hammer enamel. Crankcase covers due to polishing found a mirror finish. The saddle cover made of colored textvinite looks quite modern. By the way, the double saddle itself is somewhat wider than usual and more comfortable in shape.
The power of the new "Jupiter" remained the same, but the IZH Planet-2 motorcycle became stronger by more than two Horse power s. This made it possible to improve the dynamic qualities of the motorcycle and increase the maximum speed to 105 km/h. Increasing power to 15.5 liters. with. achieved by reducing the volume of the crank chamber, a slight increase in the compression ratio and the use of a K-36Zh carburetor with a diffuser diameter increased to 27 mm.
Not stopping at design features new carburetor, we want to briefly talk about its advantages over the previously used K-28. The scheme of the K-36Zh carburetor with a fuel corrector removed from the diffuser zone provides a more economical composition of the mixture and a reduction in fuel consumption by 4-6 percent. The enrichment of the mixture in the K-36Zh carburetor, unlike the K-28, is achieved by rotating the corrector lever clockwise. You need to use the corrector when starting the engine in cold weather and when driving on top speed. The flange fastening of the K-36Zh carburetor to the inlet pipe with two bolts is stronger than the K-28 fastening, in which the clamps often broke.
The bearing design of the secondary shaft of the gearbox has undergone a change. In the new roller bearings, the length of the rollers has been increased from 8 mm to 12 mm. However, they are installed without changing the seats in the crankcase. This is especially important for engine repair and spare parts provision. In addition, the barrel-shaped rollers allow for a more even distribution of stress along the length. Extended, bubbling rollers will increase bearing life by more than 1.5 times.
Now a few words about the changes in IZH-Jupiter.
Although the durability of the bearing of the lower head of the connecting rod crankshaft
IZH-Yu is quite sufficient and the bearing can withstand over 30 thousand kilometers, there are cases premature exit him out of order. This is due to exceeding the permissible speeds in each gear or "gasping" on Idling during warm-up, when the shaft revolutions significantly exceed the maximum power revolutions.
The redesigned connecting rod has now improved bottom smut roller bearing lubrication. This, in turn, increased the resistance several times when the engine was running at high revs. Changed worm shaft and shift forks. This is done for a clearer and more durable operation of the switching mechanism.
Rice. 1. Oil seals protecting wheel bearings: a) a felt seal used on the IZH-Planet motorcycle, b) a motorcycle rubber seal
An important innovation that increased the overhaul run of Planeta and Jupiter is a new design of oil seals to protect wheel bearings from dust and moisture. Previously, a felt gland served for this purpose (Fig. 1, a). It did not provide sufficient sealing and, moreover, required frequent replacement. Rubber seals (Fig. 1, b), which replaced the felt ones, almost doubled the service life of the bearings.
Rubber sealing rings are also installed in the pendulum fork.
They significantly improve the protection of the fork bearings and thus increase their service life.
Rice. 2. Location of the brake light switch: a) brake light switch on the frame of IZH-Planet, b) brake light switch IZH-Planet-2 in the tool box.
In spring and autumn, the brake light switch (Fig. 2, a), mounted on the frame under the brake lever, brought a lot of trouble to motorists. It was not tight enough and often failed due to oxidation of the contacts.
The new switch design shown in fig. 2, b (it is located on the tool box), ensures its reliability in any conditions.
Both models have new relay-regulators. They are distinguished by the best vibration resistance and stability of adjustments, and this is important for the reliable operation of the engine.
On IZH-P2 and IZH-Yu2, a special polyethylene tray is placed under the battery. It will protect the toolbox from corrosion due to electrolyte ingress.
The modernization of motorcycles also touched on such important components as brakes. Analyzing the operating experience of tens of thousands of cars, the designers came to the conclusion that with a large mileage, the brakes sometimes lose their reliability. And adjusting doesn't help either. brake system- Linings and ends of pads wear out. As a result, when the cam is fully rotated, the pads are weakly pressed against the brake drum. During repairs in such cases, steel strips were welded to the end of the pads to compensate for wear. AT new design cast aluminum brake pads a special compensator is provided. Now, with a lot of wear, under the steel heel located at the end of the pad, you just need to put the washer, which will be included in the complete set of the motorcycle. Comparing the old stamp-welded and new - cast - pads, it can be noted that the design of the latter is much more rigid. Pressing a steel bushing into the seat under the brake cam should make the operation of the brake system drive more reliable.
Rice. 3. Collapsible muffler IZH-Planet 2 and IZH-Jupiter 2
The exhaust system has also changed. And before, IZH was not considered a “loud” car. However, the sound of the exhaust and the design of the mufflers did not satisfy the designers. For new models, new exhaust silencers were developed and tested (Fig. 3). Their collapsible design allows, without removing the muffler body, to disconnect the tip, remove it, clean the “stuffing” and reassemble the muffler. In addition, an increase in the volume of the muffler and optimally matched exhaust passage sections make the motorcycle very quiet.
Taken together design changes, which we talked about, will increase the warranty mileage of motorcycles IZH-Planet 2 and IZH-Jupiter 2 compared to IZH-Planet and IZH-Jupiter by 25 percent.
Each motorcycle comes with a spare parts kit. Now it has increased: it additionally includes a clutch cable and a tire pressure gauge, which will make it possible to maintain the required pressure in the chambers. This will ultimately affect the life of the tires. For motorcycles IZH-Jupiter with a side trailer, an asterisk with nineteen teeth is given. It is necessary when driving without a trailer.
And in conclusion - a request to motorists. The plant receives many letters from the owners Izhevsk motorcycles with comments, suggestions, questions, advice. I would like to receive data on the service life of components and parts in these letters, indicating the motorcycle model, year of manufacture, nature of the malfunction, mileage, operating conditions, load.
Analysis of materials describing the operation of vehicles in various road and climatic conditions will help the plant to quickly solve problems for their further improvement.
G. PISAREV, V. ABRAMYAN, engineers
A motorcycle in the USSR was a popular vehicle, since not everyone had money to buy a car, and in general there weren’t enough cars for everyone. Then the motorcycle was affordable and inexpensive. And one of them is IZH Jupiter 2.
The first IZH Jupiter rolled off the assembly line of the Izhevsk Motorcycle Plant in 1961. At first he was given the name IZH-58, but then the boring numbers were replaced with a fashionable space word. Jupiter was at the top of the range of factory products. Why is there a factory one, many motorcyclists considered it the best Soviet motorcycle - powerful and fast.
The second generation model is very similar to the first Jupiters. How is it different? Probably nothing. The crew of the then Izha was one hundred percent the development of Soviet designers. A tubular frame, a soft telescopic fork, deep mudguards, side glove compartments for all sorts of things - Jupiter got all this from the 1-cylinder model almost unchanged.
Izh Jupiter 2 received a completely new, 2-stroke, 2-cylinder, air-cooled short-stroke unit with a volume of 350 cc. and 18 horsepower. The engine is very reliable. Even after 40 years, it comes to life with a half turn and pleases with a characteristic ringing sound.
The motor is very responsive to the throttle. He has a real athletic flair. The first gear is engaged with the clutch, and then, like the Jawa 350, you can switch without squeezing the handle. Acceleration is so vigorous that it takes your breath away! The sofa chair allows you to almost lie on the tank to accelerate to a maximum speed of 140 km / h.
IZH Jupiter 2 motorcycles were produced both with and without sidecars. The speed of the loner was slightly higher than the sidecar version. Consumption of 6 liters per hundred at that time was considered economical. The engine is powered by a mixture of gasoline and engine oil. In the 60s and 70s there were columns selling it.
The second Jupiter had a long life. Following the second, a third, fourth and fifth model appeared. Well, then, like all Soviet motorcycles, it took funds to re-equip the plant. No money was found, and that was it. So IZH Jupiter 2 became history.
It is impossible not to exaggerate the contribution of the Izhevsk plant to the development of motor-building. The first IZH models replenished and surprised the motopark. "IZH Jupiter-2" is precisely the crumb that endured all the hardships of the lack of copies on its own two. "Jupiter" has become not just a favorite of people, it still holds the high title of a legend of motor industry. New design, good specifications, endurance, strength, and most importantly, cheapness - these are the components of popular success. "IZH Jupiter-2" can still be found on the roads. And it has a lot good reasons. So what kind of motorcycle is this? You need to start from the beginning.
History of creation
The motorcycle "IZH Jupiter-2" began its journey back in the distant "sixties". The first copy was published in 1957. Then it could be seen at the world motorcycle exhibition under the simple and nondescript name "IZH". The prototype of the future "Jupiter" was IZH-56. It was the single design of this motorcycle that became the basis for further linear two-wheeled transport.
IZH Jupiter-2 was produced only in 1961. During the mass production, this bike got its proud name already known to everyone. The motorcycle lasted quite an impressive time. The last copy came out exactly ten years after the start of the launch - in 1971, IZH Jupiter-2 stopped descending from
Novelty, or What gave the world the second "Jupiter"
The motorcycle differed little from its predecessors. Although there were technical and structural differences. The new design is a separate issue, but the appearance of the model has been radically redesigned. Now "IZH Jupiter-2" began to look differently. Scheme electrical supply also experienced modernization. New lighting required new wiring. By the way, about her.
There are few signal lights on a motorcycle. All in all, there is a front round high beam headlight and a rear electric reflector. But by today's standards, this is not enough. Therefore, modern motorcyclists riding the "Jupiter" are required by law to put side turn signals. The engine has also been redesigned.
"IZH Jupiter-2" - the photo will not deceive
The design of the bike for the sixties is pretty good. Looks good "IZH Jupiter-2". The photo cannot fully convey all the colors of the motorcycle. Large chrome exhaust pipes, which run parallel to the ground, immediately attract attention. A neat classic frame, there is nothing superfluous on it. The wheels are shallowly planted in the wheel arches.
The compact engine, which can be seen in the middle of this picture, does not stick out from the sides. It is worth saying a little more about the fuel tank. The teardrop shape looks great as ever. Notable details include a round speedometer and the invariable inscription "Jupiter". Nearby, the very picture of this planet flaunts.
Motorcycle type
"IZH 2 Jupiter", like many of his "friends", belongs to the type What is characteristic of him? First, the main distinguishing feature each "classic" is a direct fit. The seat is not moved back, not planted low, it is even. This chair makes for a pleasant ride.
On a long road, in order not to get tired, you need to keep your back straight, only a classic motorcycle is capable of this. The pedals are not thrown forward. They are tucked under the driver. Thus, when supporting, a right angle is formed. The legs do not get numb from this, which is very important. The low steering wheel improves handling. You don't have to reach far to grab the horns. The classic motorcycle feels good on both good roads, and in poor surface conditions.
"IZH Jupiter-2" - characteristic
All "rattles", appearance, innovative details do not matter much. The only thing worth paying close attention to is the technical specifications. They can tell something about the bike that hides the shine. And so, the main center of any vehicle, and a motorcycle belongs to these, is the engine. Therefore, the first thing you need to look at the motor. "IZH 2 Jupiter" has a gasoline power unit, which is classified as a two-stroke system. And this means that the pistons are lubricated by supplying the main fuel. That is, right at the gas station, in addition to gasoline, in fuel tank you need to fill in engine oil. At first glance, there are many details, but once you get used to it, you don’t notice it. The Jupiter engine has only two cylinders.
Their total volume is three hundred and forty-seven cubic centimeters. The IZH motor is capable of developing a power of nineteen horsepower. This is normal for a light bike. The good old carburetor is responsible for the fuel supply. Don't forget the main thing: practical characteristics. "IZH 2 Jupiter" on relatively flat terrain is capable of speeds of one hundred and ten kilometers per hour. Fuel consumption is small: four and a half liters of the "eightieth" per hundred kilometers of the working path. Cooled "Jupiter" with the help of air currents. Not very efficient, of course. But for that time it was relevant.
Tuning a classic model
It's no secret that IZH 2 Jupiter has been produced for a long time. Not many people may like the old, worn look of the motorcycle, someone wants to see something of their own in this bike. There is only one way out - tuning, in a simple way - restructuring. As one of the non-capital options, you can consider painting. New bright colors will breathe a new soul into IZH 2 Jupiter. From this, the bike will play in completely new colors. Other craftsmen simply remove the stroller, if there is one. A lone moto looks much more spectacular.
"IZH 2 Jupiter" not without reason acquired the title of people's motorcycle. Everything about him speaks of perfection.

In my childhood of the 90s, when most people did not have computers and spent their free time on the street, the time came when the owners of first mopeds appeared in the yard. mostly holes with pedals, less often in the Carpathians and Riga. A year or two later, they already came to the yard at Voskhod, Minsky, Izhakh, most often without documents and without category “A” rights. Own Java, and even more so latest model at that time, it was the height of steepness. But most of my peers 14-16 years old moved on two wheels with pedals and a two-legged drive, jealous of the guys in helmets.
The boy of those years could not have a motorcycle for several reasons:
1. Parents do not allow. (and rightly so).
2. No money (in the yard of the 90s).
3. You don’t need this yourself, he doesn’t know how and in general it’s better to do homework :).
My choice was #2.
When the desire to own two-wheeled vehicles overcame all possible boundaries, the brain began to think about how to make money on it.
There are not many options at 15 years old. He dragged corn from the fields, boiled it and sold it in the market. I saved up 800 rubles in a month!
As a result, the following year, in the spring, I bought an IZH Jupiter 2 with a sidecar for 600 rubles. and gave 100 rubles for a general power of attorney.
Photo 1999. Here I am 16 years old.
That was the time! Gasoline cost 3-4 rubles a liter, in the pocket was also no more than 10 rubles. After some time, I unhooked the cradle, drove the motorcycle to the dacha and spent the whole summer and autumn riding it.
In winter, I decided to make it a cool sports bike, black and red, with a fire on the tank, with a raised wing. It is not difficult to guess what came of this, and after a year of inactivity in the garage, he was sent to the village, where he was revived and changed to grain.
Time passed, but the idea to buy IZH Jupiter 2, restore and ride remembering childhood never left.
Studying, the army, marriage, work, a small child, again work and business trips, did not give thoughts and a chance for a motorcycle and free time around it. Finally, approaching the age of 30, when my capabilities became a little closer to my desires, I sat down on the Internet in search of a Jupiter 2 in good condition and complete set.
But it wasn’t there, for everything more or less alive and intact, the owners asked for the amount that arose in their heads apparently after a strong blow, arguing that it was already a rarity and its place in the museum, and not, as it is now, near the crap .... barn .
Once I pressed my grandparents to the side of the road (he did it very politely).
I say - "Sell your father a motorcycle, I will restore it and keep it."
Grandfather - “What are you going to restore in it? He is so in good condition and in general the whole.”
- "Well, I'll paint it ... sell it, buy yourself a modern Jupiter."
- “I don’t need a modern one, I’ve been on this all my life. I’ll die, then I’ll sell”
“But how do I know that you are dead?”
- “I, he says, remembered your numbers, they will inform you”
Grandfather got caught with humor, parted. Such people do not sell their friend, children and grandchildren do it for them later. Either the price tag for a rarity, or for scrap, after they roll it away.
Months passed, it became a habit to watch ads for the sale of motorcycles in the evening. And then somehow it comes across - IZH Jupiter 2 is for sale, the price is 10 thousand rubles. The photo shows a complete motorcycle with good chrome.
There was one thing, but three weeks earlier I bought an IZH-49, around which all my free time spun. The wife looked at the ad
and said - go and pick it up, then you will regret it, we will ride together. I thank her for this, for her understanding and full support.
in my hobby.
Arriving at the place, I found that the motorcycle was assembled on a non-native frame, the right glove box was from the third series. The price dropped to 6 thousand rubles
and I was happy to take him home. It was winter, but it was impossible not to drive, especially since it started up perfectly. All lighting equipment worked, up to the signal.
In the photo I am 30 years old. Find 10 differences from the photo above))))
The motorcycle stood for a year, IZH-49 was occupied all the time ... Finally, I decided to take it apart. I already had experience of how to make less “extra movements”. Expected to take to the sandblasting and paint in the powder chamber. Under the order, I picked up a beautiful beige-milky powder color, with gloss, and took black for the frame and chassis parts in order to dilute the monotony.
Unfortunately, things didn't turn out the way I wanted. Beige powder paint was of poor quality. The output turned out to be a matte yellow color, while the black one lay well and correctly. I had to manually re-clean off the powder paint and prepare for the usual painting with cheap car enamel, for drying in the chamber.
I hoped to catch the remains of chromium under a layer of dirt and oil, but, the shiny surface of the exhaust pipes, this is cleaned
shiny bare metal. I decided, until I get a donor, to paint them in the color of the motorcycle. Should not burn, on early IZHs
fully painted at the factory.
After painting. I chose blue. There are no documents for it, so I didn’t become attached to beige, which I didn’t really like
Quotes! Tape from the first experience with IZH-49 into the furnace! You need masking tape. Automotive masking tape ZM costs 200 rubles for 5 meters, but you need 20. I found it in a hardware store, rough, thick, but alternative in price - for 40 rubles.
I bought a very successful paint, the color from it really gives off chrome, and not silver.
