Russian Bike Nut

Russian Bike Nut (3/3)

  1. I had a IMZ M72, very similar. The crank was bad, but not cracked. What happens is the lobes or the con rods slip on the radial axis, so the pisto s bind up- the crank does not spin freely. I think mine was damaged by the previous owner. The bike was left outside for years and the piston rings had rusted to the cylinder walls. He had been standing on the kick lever trying to break it free and twisted the conrods into a different axis.
  2. Are the floats plastic or brass? The benzene in today's ######ty gas can impregnate the plastic floats and they swell up or even allow fuel inside. Maybe switch for new floats and needle, too, just to be thorough.
  3. Rebuit my transmission, got it back in, everything buttoned up except this stupid spring. Is there some trick to stretching it onto the post? It's been chucked across the shop more than once now, along with lots of cussing!
  4. Does anyone have a simple, legible, English language diagram they can share? The ones I've found online are either in Russian or they don't print off well. Thanks!
  5. Bump. RP, I did get a 7AH. I need to know the key positions now. Can anyone tell me what are the positions for Lights, Ignition, etc? Close to installing the ignition and don't know which position is ON. Also, I am hooking a Dnepr sidecar frame to this 98 Ural 1WD bike. I have a brake backing plate. Should there be a thrust washer between plate and swingarm, on the axle? There's a slight bevel on the axle Or is there one inside, between the wheel guts and the plate? Hard to see from the parts diagrams I've found online.
  6. How thick a wall should the sleeve have? I have a lathe, so I could keep things balanced, hopefully.
  7. What grade steel, and how long a sleeve? Did you drill holes and plug weld it as well as welding the ends? I was thinking of boring out a piston wrist pin for the sleeve. Too short?
  8. Incidently, also looking for a shock and a sidecar fender, for Dnepr sidecar frame. Cosmetics not important. Going for the farm truck look, lol.
  9. Rewiring my 97 650. Planning on using a C5 ignition. I have been looking at the Blue Seas fuse blocks. Id like to put a car battery on the car. It doesnt have a tub. It will be a flatbed cargo car, with a toolbox mounted aft, for the electrics and storage. Anyone done this scheme? Any advantage to deep cycle vs typical car battery? I have the 424 alternator.
  10. Has anyone done it? I have a Dnepr gearbox that I would like to use, Can I cut the shaft, sleeve it, and weld it safely?
  11. Anyone sell a kit of replacement stainless nut/bolts for this bike?
  12. I had a Dnepr/IMZ flathead.54-56, I guess. I rebuilt the whole rig. Simple to work on, and generally better quality metallurgy and parts than my 90s 650 Ural. The top speed with a sidecar is maybe 65, and I wouldn't take it on the slab. Great fun on backroads.
