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 maintenance manual, here it is possible to see pictures http://www.moped.ee/manual/d4-57L.pdf
And here it is possible to see comparison of the Russian engine and Chinese...
