IZH "Planeta-5": tuning not only for speed but also for the soul

The Tuning of the motorcycle IZH “planet-5” is the dream of many boys that they sometimes begin to realize only at a Mature age, when I can afford to purchase a product of the Izhevsk plant. Then to engage in “Planet-5” can be close. Such “operations” joined by their children and grandchildren male and sometimes female, to join the amazing and mysterious world motodel.

Motorcycle “planet-5”

Motorcycle “planet-5”, the production of which started in 1985 and completed in 2008, is amenable to fine tuning. Often carried out tuning of the exterior of some units or basic units. To make the fifth “Planet” more spirited and passable (in fact, to alter IZH “planet-5” in a motocross bike), removed the unnecessary frames to reduce the 180-pound curb weight in the form of a motorcycle. Then it moves on the rear wheel put a long stroke shock absorbers and replace the front fork. It can be moved from motorcycle “Java” with power swing. Of course, change and wings.

The engine of radical changes are not carried out. To increase the service life of the crankshaft bearings change native from the secondary shaft to “janowskie”. The quality and increase the resources the high cost of these bearings to compensate.

For motorcycle IZH “planet-5" engine tuning is the increase in the volume of the cylinder. To do this, cut off its top, the sleeve chiseled to 76 millimeters. Under this size will fall freely from the piston “Planet-sport». After these modifications the prototype of upgraded “Planet-5” will develop speed to 160 kilometers instead of their 120 kilometers per hour. By the way, on the test bench the motor developed power of 42 BHP at 5950 rpm. But any crossing of the motor reduces its resource. Such changes should not be performed on the motorcycle, designed for everyday normal driving.

To increase the power of a motorcycle engine IZH “planet-5”, the tuning of which is considered in this article by increasing the speed of the upper edge of the exhaust window trim and a half-two millimeter. Obligatory – equal weight pistons, with Windows to match needs the cylinder with vent Windows, not cover them in any case. Have the piston rings with the edges must be chamfered. Piston pins should be facilitated by a groove on the end of the cone. From the end of fingers also be chamfered. Need bite “tails” locking, so they do not cut the piston pin. The cylinder heads need to pull your trim off their ends on a lathe.

Tuning motorbike ‘planet-5”: finalization

For finalization we need to find the crankshaft that holds the top of the needle bearing. This shaft can be found on “liquid” «Jupiter». It is interchangeable with other models of IZH. In the head it is necessary to drill 2 holes with a diameter of 3-3,5 mm, as is done in “Planet”. Staff separators from aluminum, installed at the Izhevsk plant, reliability is no different.
After the alterations will have to use the AI-92 gasoline.
