Dneprglide
Some help needed, I have a “Dneprglide” gearbox with an fault !
In second gear it looks like it goes faster and slower constantly.
So I shift very quick in third, no problems at all.
Mentioned causes, takes another gear the same time, oval gear, friction with another gear !
How do I find out what the problem is, and more how do I fix it !!
PS another member of the UDCN has the same problem in third !

Mystery II
Michael from Denmark would like to know more about the frame he has !
hi John,
thanks for helping me. I would really like to know which model it is,first the holes has always there.They have not been weld later on.
Thought a BMW R75 engine would fit inside it,from hole to hole is around 33,5 cm.
Where I have my finger is on the steeringhead,is a very littel stamp,se the photo with my drawing number 1.There is not stamped anything on the frame any place as the normal.The frame at the back is a original R71 frame,just for see how close it looks. Where I have my finger at the rearbrake plate, is stamped the things you see on my drawing number 2. The frame is without the reinforcement at the back suspension
regards michael

Dnepr/Ural “stubby” front fork
Hi Catwesel,
Note, he means B-Cozz community 😉
I have a Dnepr/Ural “stubby” front fork. It’s a nice piece of engineering but I don’t need it–my only Eastern motorcycle is a 1951 BMW-SAG R35/2 (EMW). Is there a classifieds section to your website? The fork is complete except for the upper triple-tree. It looks straight, and the headlight ears are nice. The rubber bump stops aren’t too hard. Is the steering tube supposed to be parallel to the fork legs? It’s not–it leans back a few degrees. I am in Baltimore, Maryland U.S.A.
Thanks, Paul
