DAKAR 1983 | Le Morini Camel 500 three specimens were at the start of the Paris-Dakar.

The tormented path of Transafrica 80 (the race of six thousand kilometers through the African savannas and deserts) was the best development for a prototype of the Morini motorcycle from which the Carne model was obtained! 500, today offered on the market. The preparation of that prototype for the African test was carried out by Antonio Valentini, the same preparer as the three Camels 500 sponsored by Za nussi and participating in the Paris-Dakar. The machine is the result of the competitive experience of Valentini and his team and the technological evolution of the Bolognese company (founded in 1937 by Alfonso Morini) and the collaboration of Zanussi Elettromeccanica which provided the electronic ignition system.

TESTED IN TRANSAFRICA 80 IN COLLABORATION WITH ZANUSSI ELETTROMECCANICA

Faced with the difficulties of a route such as that of the Paris-Dakar, that puts a strain on all parts of the vehicle and some specific needs imposed by the characteristics of the race, the twin-cylinder from 500 CC. has undergone some modifications and has been subjected to careful checks on the. First of all the engine organs were controlled at the metalloscope, after a thorough examination of the size. The compression ratio has been adapted to the quality of the petrols available in Africa, poor octane.

The tank has been increased and has a capacity to 34 liters: it is also equipped with an anti-slip sponge. The air filter has been completely moved and is in a dust-sheltered position, sand. stones raised by wheels The saddle, Car. has been equipped with double padding and the lighting system of a double front light. But the most interesting novelty is the elimination of the battery with the adoption of a transistorized system for ignition. A system produced by Zanussi Elettromeccanica of Bologna, company belonging to the Zanussi group of Pordenone.

There are two functions that the plant is called to perform: electronic ignition and power supply of light loads. The system provides electronic adjustment of the most effective value in the alternating voltage provided by the flywheel-magnet-alternator. In electron-ca ignition. the procedure is structured as follows:: the flywheel-magnet-alternator produces alternating voltage, which is partially straightened to charge capacitors placed on high voltage electronic transducers. An electrical signal, which originates from the collector, controls the discharge of the capacitor on the primary of the transducer's high voltage coil.

In this way,. on the secondary connected to the candle, the voltage necessary to make the spark necessary for ignition is obtained. With regard to the supply of light loads. The flywheel-magnet-alternator generates an alternating voltage whose effective value is controlled by the electronic regulator in alternating current on which the light loads are inserted. On these it is established, starting from a minimum number of engine revolutions. an almost constant voltage that is not affected by changes in the number of the engine.
