Engine housing D6 with cylinders, head, piston and crankshaft D8. Old school.
Hello, I am looking for help
I want to build a moped bike with An engine looking same as in picture which I got from russia
I need some auxilliary parts like chain and rear sproket
Can I find manual and spare parts online?
I suggest sendng a message to Dagger who started the post. He's probably best placed for Russian spares information. Most D- type motors used these days will actually be the Chinee derivatives.
ok anyone have a link to the manual for this engine ????? i need to know the cc's yes i bought the one on Grubees site for $1000 but didnt pay that exactly LOLOL check out my bikes at https://www.facebook.com/DRBS-motorized-bikes-218344788758332/
ok who has the links to the manual for the russian engines??????
i need the manuals for these engines
You just asked for the manual 3 times. lolz
The D-4 was the first to go into production in Russia in 1957, I think(the year).
Maybe the engineer that it 18 years designed earlier in 1939 had some D-1, D-2 and D-3 as prototypes.
The D4, 5 , 6 and 8 were all 48cc's.
It was a law in the USSR back then, that a bicycle's engine could be up to 50 cc's and have up to one HP.
Nobody would make them bigger and I don't see any reason for anyone to have even made any custom "mini" models, lol. 48cc's is about as weak as can be used. Lol,
I have a mig-21 I have had laying here in a box for a few years. This thread has sparked my interest and I may have to dig it out and try it sometime. Have been curious to how it compared in power to a 66cc China girl, but have never mounted it to find out. It definately appears to be much better machined then any of the 20 China girls I have owned.
Loved this thread! Innovative craftsmanship, multinational participation and the real history of the Chinese bicycle engine. Thoroughly enjoyable. Many decry the China Girl but I was relatively pleased with the 3 or 4 that I built. So were the buyers of those bikes. I think a lot of it is care and proper maintenance.
