Thanks for the link! That is good history of the origins of the CG. Grubee fits in there somewhere.A good thread on this topic.
The Russian engines D-4,D-5,D-6,D-8. History.
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...motorbicycling.com
A build thread using a D series engine. Thread 'Russian engines' https://motoredbikes.com/threads/russian-engines.3881/
While I agree with the changes in design, mostly due to the fact that it cut costs, these engines did lose some charm. Did gain a good bit of power though.
If only the cut cost went right back into quality control...
