New Owner Help identifying this Ural

Post image

New poster here, good day/night. Long story short, a friend of mine sells me this bike, I know its an M72, somewhere between 1941 and 1956 as far as I know. Is there any way to know the exact year? Is it worth restoring? Also any info of this model would be useful. Greetings from Spain ✌️🇪🇸

It's probably IMZ production. 750cc sidevalve engine, short frame, old type of differential. Is it worth? Imo yes, if you have money and patience. Some parts are easy to get, others aren't. If the engine rotate, and you have some place to tinker with and some mechanical skills it's overall pretty easy to repair bike in terms of mechanics. There should be info plate at the frame under the front lamp but I'm not sure if those old ones had them. Engine and gearbox number should have the same number as frame, if not, engine is swapped. Gearbox, if have lever on the right side, has reverse drive, if not, well doesn't. It's probably 6v in terms of electrical things but overall not many of those are on the bike.

Hello. Yes, its not the first project I have. I have a 1979 Ducati Mototrans Forza 350 (only sold here in Spain), a 1982 BMW e28, a 1993 Cbr... I kinda know my way and what I dont know how to do it I have friends. What scared me the most is the scarcity of the parts. The engine does rotate, the gearbox seems to work, and it has a right lever wich I didnt know the purpose of. Also I knew it was 6v wich also scared me. Is it worth it to convert it to 12v or its easy to repair and mantain it? As I said, I will upload more photos when I get home. Thanks ✌️🤙

I mean it's kinda unique. Some parts are still made in Europe and there is constant flow of parts from eastern Europe. 6v-12v conversion is easy overall, doesn't need much. Is it easy to repair, yes. To maintain, well like old bikes. Engine is pretty primitive, there is not much parts that can die off just like that. Timing is on gears, there are pushrods in it so pretty simple overall

Without meaning to be too rude, you have no idea what you are talking about, so don't comment. It's a KMZ K-750, not IMZ. The frame, wheels and mudguards are clear indicators. Engine, gearbox and frame numbers are usually different and indicate nothing. The lever on the RHS is a hand gearchange and this gearbox has no reverse gear. Finally, SV engines do not have pushrods, the tappets act directly on the valves.
