The Izh Jupiter 5 motorcycle is today considered one of the best Soviet bikes, so to this day hundreds of satisfied owners are trying to improve it. The best improvement to an old motorcycle is its tuning.
Izh Jupiter 5 was produced in a standard form, because in those days people loved simple but high-quality equipment. Today, many people want to have a unique, special motorcycle that would have not only excellent external characteristics, but also increased technical parameters.
Any motorcycle tuning is divided into two types: external and internal (the process of changing technical characteristics).
Previously, it was impossible to tune your vehicle, because then materials for tuning were not produced, and if you saw some special motorcycle, then most likely it was the personal fantasy of the owner. In general, any tuning is divided into external and internal (engine). But in addition to these two types, we will also look at tuning other characteristics, such as the tachometer and carburetor.
External tuning Izh Jupiter 5
Appearance has always played an important role for the owner, so anyone who wants to modernize their vehicle immediately takes on minor changes in appearance, because this requires a minimum of funds and a great desire to stand out. Basically, if you look at the Izh Jupiter 5 tuning photo, you can see that most are trying to transform their bike into a sports motorcycle. Jupiter 5 itself looks like a sports class, but modern models have a more attractive appearance. External tuning is divided into several processes:
- lightweight design;
- frame extension;
- installation of a new seat;
- chrome plating of some elements;
- installation of fairings.
If you decide to install new fairings on your motorcycle, you can use two types: a new unique part or a used fairing from another motorcycle model. In the second case, you will have to change the fastenings of the fairings, and only then will it fit. This option is the most popular, because buying a custom-made fairing will be very expensive.

Another equally popular type of tuning is chrome plating of parts. If you find metal parts on your motorcycle, make sure they shine by chrome plating. The following parts can be chromed: exhaust pipe, wheel rims, engine block and fork. You can tune other elements at your discretion.
Further, not only beautiful, but also useful tuning will be to lighten the age of the motorcycle. To do this, all unnecessary parts are removed and, if necessary, replaced with lighter analogues. And finally, installing a new seat can be an excellent option for external tuning. You can go two ways: reupholster the existing seat with leather or order a new seat from a sports motorcycle. You may also have noticed that owners often style their Jupiter 5 as a Japanese motorcycle Suzuki Bandit 650, taking from it not only its appearance, but also other tangible details.
Improving the Izh Jupiter 5 engine
If you decide to do the tuning of the Izh Jupiter 5 with your own hands, and at the same time your eyes are focused on the engine, be prepared for the fact that you will have to do some serious work. Basically, modernizing a motor means increasing its characteristics and, accordingly, power. Any tuning of the Izh Jupiter 5 engine implies two options:
- increase in volume;
- increasing engine speed.
With the first option, you will need to spend a considerable sum, because in order to increase the volume of the engine you will have to bore the cylinder, buy another piston and, if necessary, make another crankshaft. But with the right approach to such tuning, the increase in power will be noticeable. The downside of this method is that the cylinder is too fragile and may not be able to be bored.

In the second case, as the speed increases, you will have to adjust the valve timing. As you know, the timing of the distribution is controlled by the windows in the cylinders, so if you can bore these windows, the motorcycle will increase in speed and, accordingly, power. But be careful when making such an upgrade, because if you drill the windows incorrectly and add a different amount of fuel mixture, the engine will not only lose power, but will also have increased fuel consumption.
How I decided to remove paint
It was necessary to have some kind of more or less durable grinder with an attachment made of Scotch Brite of suitable grain size, with Velcro on a cup with a rubber base. The surface would immediately be obtained without unnecessary scratches (although traces of metal molding and roughly cleaned welds previously hidden under paint would be visible).
Here, for example, are traces of metal molding:
Plus, the welds would have to be cleaned with a brush made of thin steel wires - also an angle grinder or a light high-speed reversible drill with such an attachment.
But instead of a so-so drill (and this is my drill in the photo and screws screws) with the money I had, I bought a semi-professional Skil grinder with a flexible shaft for 1390 rubles (790 rubles in the configuration without a flexible shaft; the flexible shaft resembles a speedometer cable in braid), I didn’t really use a single attachment from it. I asked him to sharpen an M6 bolt for a 3.2 mm collet, sawed it at the end and put small strips of sandpaper there.
This device made it possible to remove paint from the wheel rim without disassembling the wheel (without separating the rim and the wheel hub).
By the way, never clamp Chinese 3.0 mm bits with such a collet - they will turn and you will have to buy a whole set of collets (they are for different drills) in a radio parts store, which costs 200 rubles. Probably, the collet is 3.00 mm and not 3.20 mm and you need to clamp such attachments.
Included with the grinder was a pencil-shaped attachment made of diamond-coated steel. She was able to trim welds and draw on glass jars (the part with the largest diameter). These are sold in separate sets, but it’s still a shame to trim the metal with them.
You have to add machine oil to the flexible shaft of the grinder - in the place where it connects to the grinder, it then leaks out and ends up everywhere - on the floor, mask, face and clothes. It is better not to set the speed above positions 3, 4 or 5 during different operations set by the speed controller (there are 6 positions in total), since the motor in it starts to heat up too quickly at high speeds, the smell of insulation appears and you feel sorry for the sander.
Almost all the paint and rust was removed from the motorcycle with this sander. A grinder in addition to a grinder like this would be much faster, perhaps two or three days for all the parts including the frame. Some parts were cleaned by hand. It’s more pleasant to work by hand; there’s no rush like with a power tool. I would have done exactly this without a sander.
The best thing is a durable air compressor with sufficient liters per minute and air pressure capacity, and a few tools to go with it (a durable straight sander with easily replaceable bearings and a small angle sander with a rubber backing for Velcro). The rotation of the attachments in such tools simply stops and they do not get knocked out of your hands like a power tool - which often has a kilowatt of power to withstand possible overheating from prolonged use.
Installing two carburetors
If you decide to tune your motorcycle to the maximum, you can increase its performance by installing two carburetors. As you know, Izh Jupiter 5 has 2 cylinders, and accordingly you can put a carburetor on each of them.

But be careful, because you will have to properly balance the fuel supply. As a result, the motorcycle’s power will increase significantly, which is the main goal of engine modernization. If you want to do a similar procedure yourself, be sure to look at the Izh Jupiter 5 tuning video, which should be plenty on the Internet.
How did the motorcycle turn out the way it is?
The metal is sanded and coated with clear acrylic varnish. Selected color combinations and everything glossy are still boring from fiddling with computer programs. I wanted something like the so-called post-apocalyptic industrial theme. Here, for example, from the Detroit Bros workshop:
In general, I decided to assemble the Jupiter without the side borders and so that it would all shine with the steel from which it is made.
I bought a kilogram package of car varnish, it turned out to be acrylic, from Vika (about 500 rubles). I also bought thinner for acrylic paints and varnishes, also from Vika (a couple of jars for 90 rubles each), but later the hardener ran out faster than the thinner (a small jar of hardener was included with a jar of varnish). It seems that the domestic solvent R-12 is friendly with any acrylic paints and varnishes, but I have not checked.
I planned to paint with a purchased touch-up airbrush from MATRIX - with a simple round nozzle, a 0.2-liter aluminum tank, designed specifically for regular paint (not for all sorts of filling primers, which require a large diameter nozzle, greater pressure and, accordingly, greater air flow), produces spot from 5 mm to 4-5 centimeters, economically consumes paint.
I bought this touch-up airbrush for 690 rubles. And for 200 rubles a filter drier is small for him, for another 50 rubles for a set of two flanges (for a thin oxygen hose) and two nuts for a bayonet connection of such a flange to the airbrush.
On occasion, I got the compressor quite inexpensively, homemade, from a compressor from a refrigerator, a small receiver, a pressure gauge on the receiver itself, and an oxygen reducer with a thin oxygen hose. I've already modified it a little:
And also modified:
Steampunk compressor:
Such a compressor will not handle spray guns with high air consumption, but my touch-up airbrush works, and a small airbrush will work even more so. Although you can try a small spray gun with an LVLP spray system (originally made to work at low pressure and air flow) from IWATA, for example (I saw it on the Internet for 2300 rubles). But the compressor works no louder than a refrigerator. Otherwise, I would buy a compressor from my next salary (this is approximately 5,000 - 7,000 rubles).
Installing a tachometer on Izh Jupiter 5
Very often, owners of this model change the standard tachometer and the dashboard in general. An excellent and inexpensive analogue would be the dashboard from a VAZ 2106 car. You can take a speedometer, tachometer and temperature sensor from the car. All these parts fit perfectly into standard motorcycle holes. Optionally, LED lighting can be installed on the new dashboard.
Suspension upgrade
The standard suspension of the motorcycle in question is quite reliable and has good maintainability. However, its characteristics can be improved somewhat. To do this, perform the following steps:
- Install adjustable gas shock absorbers. They are easy to find in specialized stores. As a result, ride comfort and vehicle stability on the highway are increased.
- Change the front fork. Most often, this process is accompanied by reworking the fastening of the part.
- Install an ergonomic steering wheel.
