    I think all balls has to be almost 30mm in diameter but in time maybe the balls has worn out, as you can see the M72 balls are smaller but also the oldest and the Dnepr balls are from 1991.

    I have measured the balls, Ural M72 has 27mm, Ural M63 has 28mm and Dnepr has almost 30mm.

    I was in my garage at least ten times in the last week but I always forget to measure the balls and I have four sidecar frames in garage.

    If I will not forget I will measure on my frame tomorow.

    I have finished the BMW R60/5, this is the last video for this BMW on my youtube channel: Now I am working only for the BMW R35 and I realy hope that I will finish the bike by the end of the june and after that I will be able to finish my M72 bike.

    It will fit whitout problems on the head light mounts but you need to modify the electrics. Topic here:

    And now I have all the parts painted, I have painted again the headlight shell because i had some minor scratches due to the work done before for electrics, front fork, etc. Small progresses but I will succed one day to finish the bike...

    I had some time this weekend and I have work on carburetors which were having problems from the factory. The carburetors are new chinese PZ28 model copied from the russian K37. Now they are working quit good with a good throttle response but I recomend these carburetors only if you want to keep an original look on the bike.

    It seems to be a MT9, the frame has short gussets for rear shocks. The engine is 100% a MT9 engine, it has 6V generator and 6V ignition. We need more pictures... the tank is a the new version starting from MT10 and the seat is not original. Here we have a catalogue: http://dnepr-kiev.com/catalogue-of-spare-parts-dnepr-mt-9-10

    I don't know for MT10 but on Ural M63/M66 was the same speedo as it is in K750, KMZ K650, Dnepr MT9. From a mechanic point of view they work exactly the same starting from Ural M72 until the last Dnepr was built: 1. Wheels on 19 inches 2. Rear drive ratios are the same Just fit one in the dashboard and it will work.

    I have bought from Ural Zentrale rims for M72 and these are made for 4mm spokes but I manged to put them on Dnepr brake hubs by enlarging the niple holes. The rims are good enough but I recomend these rims only for paved roads only because the material is thinner then the russian rims.

    Working on electrics and I am almost done, everything is working and I just have to start the bike in order to test the electronic relay (Vape R81). After the test I have to paint the fenders and the front fork parts and begin the final assembly for the bike. Below the rear light, quit bright for a 6V chinese copy:

    It should be on the left top mount of the shock absorber. Also keep in mind that some series of the russian bikes did not had frame number, only engine number which apeared in the papers.

    I believe the problem with the springs is not the heat but the poor quality material of the springs. For example the Ural engines does not have this problem, also the boxer BMW aircooled engines which don't have an insulator shim under the valve springs.

    I have managed to adjust the position of the front wheel by milling the front brake plate, 3 mm in the center: and 2 mm in the outer diameter: Now the wheel is aligned in the center of the front fork and fender. After that I have painted the gas tank, no filler and no polyester, just paint because as I have mentioned before this is not a final project. The gas tank was treated on the surface with an antirust compound: Green paint semimatt finish RAL 6003:

    I believe on J&P Cycles you can find old model Harley rims that fits for russian boxers.

    Yes, it shouldn't be overlapping but those brake shoes are not NOS but aftermarket parts and they are not always fit perfectly. The "bright" side is that area is not braking very hard even in a perfect braking sistem.

    Summer is begining, Covid starts to dissapear, peoples try to recover the lost time. I did not have much activity on this forum because in the last two years I had another projects (Triumpf BD250 finished, BMW R35, BMW R60/5). On russian bikes I am working on my M72, I am begining to work on a M66 engine (I will show here the work) and I have to finish a Dnepr engine. So, I am still working and I am still here. I have sold the Dnepr and now I have some space in my garage!

    This is cool, nice design.

    Front brake, I have made some adjustments on the brake shoes: I have made may own clutch cable and mount which are stronger then the original ones: I have worked also for the rear brakes: Videos with the work:
  22. luca.stere
    I have 1.5mm wires.
  23. luca.stere
    I realy don't know, did not have an original harness and I did my own wiring. Some new parts, I hope these are the last of them, rear spring support: New bushes for the rear suspension axles: Rear suspension covers:

    As a profession I am a mechanic but I do it as a hobby in my spare time.
