"Java 350-638" was considered the most beloved model for motorcyclists of the Soviet era and even the era of the new Russia.
It went on sale from the beginning of 1985. The distinguishing features of this motorcycle, capable of carrying up to two people, from the remaining models are new components: electrical equipment and, of course, the engine. "Java 350-638" had innovations in its chassis. A shock absorber was installed on board the new model, which reduced the vibrations going on the front fork, making it possible to use a motorcycle with a trailer. This explains the fact that Java 350-638 did not have protective arches, as well as the immobility of the left footboard. It was installed a new saddle, casings and a gas tank with a volume of seventeen liters, more angular. In addition, rubber inserts are provided on both sides for supporting the knees. Motorcycle "Java 350-638" has improved driving characteristics, and its comfortable saddle makes it possible to make quite long and comfortable trips.
For the driver there is no difficulty when driving on bad roads, and when driving in the city.
Specifications
Innovations affected not only the gas tank and shock absorber, but also the rear light of the model, as well as the panels on the seat post. As a result, the appearance of the motorcycle has changed . Now the model has a silencer with an increased length of its front part. This not only increased power, but also improved the type of mounting on the fuel tank. The Jawa 350-638 has a two-stroke engine with two cylinders. Its working volume is 343 cubic meters. centimeter. The maximum power of this “iron horse” is twenty-six “horses” with a mass of one hundred and seventy kilograms.
Appearance
The length of this model is 2.1 meters, the width is 107 centimeters. Java 350-638 has a battery with a transparent case, side reflectors and an audible signal. Compared to all previous models, this changed the metal of the cylinders, they are made of aluminum, as a result of which the weight of this vehicle is reduced. In addition, the bore of their inter-center distance of only twelve millimeters made it possible to obtain four, and not two bypass channels, as was the case with older versions. This increases the pressure force on the crankshaft, in which a seal is used for more intensive lubrication of the bearing due to gasoline combustion products.
Innovations
To increase the durability of the engine installed on Java 350-638, as well as the quality of its work, the
clutch basket was increased, including the number of disks in the oil bath. The force of the springs is also reduced by fifteen percent. Given the innovations in the engine, changes have also occurred in reverse gear, more precisely in its gear ratio. In this model, the number of teeth on the leading star is seventeen. Motorcycle "Java 350-638" can be equipped with a front disc brake. This is becoming an absolute plus compared to its drum serial. The
rear shock absorbers of this vehicle are also configured. Fans of experimenting choose for themselves the individual rigidity that is most appropriate for their style of driving a motorcycle. Using a tachometer it is possible to control engine speed. In this case, the most optimal is the torque at speeds from three to five thousand. For better acceleration, motorcyclists use an increased speed.
