The IZH Planet 5 motorcycle, despite its age, is still in service and is often found on the roads of the country. Its first owners purchased this model for its beautiful appearance, good engine and versatility. The model turned out to be so successful that its owners could go to work every day all week, and on the weekends they could attach a stroller and take their family out of town or take building materials to their home. Nowadays, the role of this model has changed little; it is still a workhorse and a pleasant motorcycle, suitable for relatively short trips. Alas, Planet 5 also has its drawbacks: low speed, outdated engine and appearance. That is why the owners are tuning the IZH Planet 5 motorcycle. Below, you will find out how you can update the bike with your own hands, refresh or transform the appearance and make it a little faster.
Styling
The choice of where to start tuning is entirely yours; we recommend that you first pay attention to the appearance of the motorcycle. Now there is a long list of various styles and directions for which these motorcycles have already been converted. This is a cafe racer, retro style, rat bike, cross enduro, chopper, sport. Planet 5 is being remade into these and many other styles; the entire Internet is filled with ideas, and we decided to share the most popular ones with you.
In another of our instructions, you can learn how to tune IZ Jupiter 5 with your own hands.
Retro style
Nowadays the fashion for old and vintage cars and motorcycles is actively developing. Models from 30 to 50 years ago are kept in barns and distant villages to be restored to their original form. The idea of this style is a complete or partial restoration of the motorcycle to its factory appearance. The closer and better the work is done, the better the tuning of IZH Planet 5 with your own hands looks photo:
Do not think that it is so simple, because even for such a relatively new model, it is becoming increasingly difficult to find original spare parts. Particularly expensive are fragile dashboards, original trunks and dented gas tanks. You'll have to hunt for these details. It will be very expensive to restore Soviet chrome and paint all chips and scratches. This style is suitable for true connoisseurs of the brand and those who prefer to spend hours and days in the garage.
Recommendations
When tuning IZ Jupiter-5, you can make two-section “seats” yourself. A base is cut out of thick plastic to give the workpiece the required configuration. The structure is covered with a thin layer of foam rubber for furniture, then the future seat is covered with leather.
At the next stage, the tail section is changed:
- The desired shape is cut out of construction foam.
- The resulting figure is glued in layers using epoxy glue.
- After the composition has dried, the foam is cut out and the residues are removed using a solvent.
This shank lends itself perfectly to priming and painting. The rear part of the frame is welded to fit the resulting new part. External tuning of IZH Jupiter-5 includes replacing standard tires with sports road counterparts and installing new mirrors. This will give the bike a modern look and will have a positive effect on improving visibility. In addition, they install a dashboard from Chinese mopeds, control panels on the steering wheel, xenon light elements, LED turn signals and brake lights.
Cafe Racer
The style largely repeats the previous one, because it consists of giving the motorcycle an appearance similar to the British models of the 60-70s. A distinctive feature of such motorcycles is the special shape of the seat and tail. For our modification model, we will have to work on the rear part and replace the tank with a more streamlined one. You will also have to change a number of details in general, these are:
- round mirrors;
- one round device instead of a panel;
- monochrome, dim color of the main elements;
- no stickers;
- an abundance of chrome parts (switch feet, turn signals, possibly fenders).
Chopper
One of the popular options for tuning an IZH Planet 5 with your own hands is to turn it into a rocker motorcycle. The constant attributes of this style are:
- long front fork;
- small rear wheel with wide tires;
- wide seat;
- “sofa” seating;
- high steering wheel;
- plenty of dark color and chrome.
This option is not suitable for most, mainly due to its complexity. Here, first of all, manipulations with the frame are implied, which means it is necessary to have a high-precision slipway and a number of other equipment to maintain the geometry of the frame and the alignment of the wheels.
Fairing installation
This is one of the most popular procedures when tuning the IZH Jupiter-5 motorcycle. It is worth noting that this task is quite complex and requires specific skills and knowledge. The factories employ teams of engineers engaged in the development and creation of fairings. Until recently, plasma design methods were used for this; now automatic development systems are used. Finished elements are tested in wind tunnels to evaluate their behavior in air flow.
Making these parts yourself is very problematic, so it is better to entrust the work to specialists. This is confirmed by numerous user responses indicating a deterioration in the dynamics of the bike and the presence of irregularities on the surface of the fairing. The process is not only labor-intensive, but also requires professional equipment and training.
Do-it-yourself engine tuning for IZH Planet 5
Having figured out what the tuning of the IZH Planet 5 motorcycle will look like, the rider may find the power insufficient. So it is, because the factory ones are 20 - 25 hp. The original engine is enough for tight streets, but on the highway the engine stops the speedometer at 120, beyond which it is quite difficult to get out. That is why, the next step is to tune your engine. The first step is to conduct a complete audit of the main elements that affect power: ignition, air filter, carburetor, exhaust. 50% of success lies in the correct setup and maintenance of these “capricious” motor components. If everything is in order, but there is still not enough power, then there are two further options:
- The first is modification of existing units;
- The second is a comprehensive tuning of the IZH Planet 5 engine with replacement of parts.
The first option is suitable for those who are trying to maintain the factory condition of their bike. Then, to drive a little faster, you can clean the exhaust, which inevitably becomes clogged with oil residue. The next step may be to install higher flow jets on the carburetor. At the same time, we inspect the filter element; it should fully cope with its task; monitor the oil level. The last item will be replacing the spark plugs and fine-tuning the ignition. With the right approach, you can get the most out of your engine. The maximum speed will not increase, but the engine response will definitely improve. Some models have a “traction” drive sprocket with a large number of teeth; if you replace it with a “high-speed” one, you can add at least 10 km/h to the maximum speed. Riders who are primarily concerned about the sense of speed should prepare to study a lot of specialized literature, because in order to noticeably improve the engine's power, its main components will have to be replaced. It’s worth starting with an audit of the cylinder-piston group. It is best to immediately replace the crankshaft with bearings, connecting rod and piston with rings with analogues from Japanese models. New spare parts will be stronger and lighter than the old IL Planet 5 tuning will significantly improve the engine, allow it to spin up more easily and preserve its service life. Next we replace the intake system, this is a new, more efficient carburetor. Behind it is installed a low-resistance filter and another important intake element - a reed valve. The exhaust should also be replaced. Only part of the knee will remain from the old spare parts, and a special resonator will be welded behind it (diagrams with dimensions can be found on the Internet).
Due to the characteristics of 2T engines, the exhaust cannot be direct-flow; it must provide a reverse impulse, which will prevent the air-fuel mixture from splashing out of the combustion chamber. After the resonator, a muffler is installed, which in general may be absent if you prefer a loud roar of the engine. Last but not least is the ignition system. It is better to immediately replace it with an electronic one, because the contact one almost always gets lost and has to be adjusted very often. The electronic system eliminates the need for regular inspection of the mechanism and allows you to maintain the power and torque curve at any speed.
Refinement of the exhaust and intake system
Tuning of the IZH Jupiter-5 motorcycle is carried out by improving the intake part. The main disadvantage of this system is the absence of a reed-type valve and the presence of only one carburetor on the standard engine. This element does not allow you to develop high speeds and power. The optimal solution would be to install a pair of identical carburetors along with two “house” type reed valves.
It will be necessary to make new intake pipes specifically for each cylinder with the possibility of installing housings under the “petals”. The parts ensure that the fuel mixture is supplied only to the internal part, which has a positive effect on filling the cylinders with an increase in power. Carburetors can be taken from two-stroke foreign bikes of identical volume, the domestic “Ural” or K-68. You will also need to select jets for the volume of the motorcycle’s power unit.
When tuning IZ Jupiter-5, many owners believe that it is appropriate to install a forward flow with a beautiful exhaust pipe. Experts categorically advise against doing this. This solution leads to an increase in fuel consumption and a decrease in power. The exhaust system should consist of a pair of resonators. Combining two exhaust elements into one unit is not allowed. If you want to make the sound of exhaust gases quieter, install muffling nozzles.
Improved ride quality
The icing on the cake, and in our case the final touch of tuning, is the improvement in driving performance. Some of the tuners approached this issue earlier when they sawed the frame of their motorcycle or raised the tail of a future crossover. For the rest, first of all, you should get rid of your original tires. Among its advantages, only wear resistance can be noted, for which you pay with your safety. It is both universal and useless. The lugs are practically useless; if they get into a mess, under normal conditions on the highway it is noisy, but relatively holds the road, turning into a killer on a wet highway.
Therefore, without hesitation, we throw it away and purchase road, cross or all-purpose tires, based on your requirements. The second point is the suspension. If everything is generally clear with the rear shock absorbers, they are extremely reliable and, in addition, have stiffness settings, then the front fork does not leak only for those who have chosen a different brand. There are two ways to get out of this situation. The first is to add thicker oil. The second is to carry out a complete overhaul of the feathers and replace all parts. Both options do not last long, so the most demanding owners simply change the fork to an imported one, while the rest endure all the shortcomings of their iron horse.
