The Russian engines D-4,D-5,D-6,D-8. History.

[Dagger]

I will tell about engines of the Russian manufacture which use in Russia for installation on a motor-bicycle. These are engines D-4, D-5, D-6, D-8, at present, they are not made. The factory which made engines is called ,,Krasniy oktyabr".
Them exhausted since 1957, till 1990... So D-4 and D-5 were similar against each other.
These engines did not have a possibility to connect flashlights on a bicycle...

The following engine D-8 and D-8э, almost differed nothing from D-6, except an electricity, they began to develop even more powerfully a current for headlights.
There was an ignition coil, and other muffler...
D-8 - 6 volt.
