EN Circular economy principles works with nature built environment with water, air, carbon cycles with no waste. Industrial revolution enable society led to development of engine and became more powerful machines. This include motorcycle which is has a life span based on the revolution of engine technologies. Modern ignition and injection systems significantly reduce servicing. In the Dniepr MT 11 motorcycle from 1989, in accordance with the manufacturer's guidelines, the following should be checked every 5,000 km: cleanliness and fastening of the interrupter contacts, oiling the felt and friction elements of the ignition advance mechanism, and adjusting the spark plug gap. As regards the fuel supply system, the carburetor should be washed and blown out and the tap strainer should be cleaned every 500 km. Additionally, due to climatic conditions, the position of the carburetor needle should be adjusted. In addition, before working on the fuel system, check the gap between: spark plug electrodes, breaker contacts, valve stems and levers. After modernization and the use of an electronically controlled injection and ignition system, service activities were limited to adjusting the gaps on the spark plugs (every 5,000 km) and replacing the fuel filter and cleaning the filter element in the pre-filter every 30,000 km. The developed solutions confirm the possibility of improving the operation of older structures in the field of injection and ignition systems at the level of modern structures.
