In the process of doing something similar with my Beemer R80GS !
On the road....BUT,work in progress !

Evening 002,
A rufty tufty shopping trolley with a rack for all the gardening tools and the allotment produce runs. Spin up the knobbly for a bit of 'deep' cultivation! ;D
Regards, Bill.

Don't start me about the stupidity of the rule ( >:( ::) ) but if it's a 1992 model then it shouldn't be possible to mot with the chair on the right :(
If it wasn't for that it would look quite good, needs a coat of plain green to cover that *hideous* paint mind you lol, tbh I'd prefer a rh chair because the most difficult riding I'll do (strange cities, unfamiliar rules etc etc) is on the continent, UK is easy for me!
Wonder if anyone's ever put an Imp engine into a Ural/Dnepr/Dneipr...? (He says looking at the spares in the garage....!)
edited (again) to add... anyone know the front to back length of a bmw / ural engine? From front of the engine to the flywheel housing?
-
I have seen one with a reliant engine fitted.If you want a Ural engine measured I have a mate with one,I could drop round and see him if you like.

Sorry Smudge,
I didn't mean to vex u!
I suspect the gas axe dosen't have a place in this melange of mechanical mayhem? ::)
As for the Hillman 'Pimp', that might prove interesting, providing you keep the head true! ;D
My regards, Bill.

No worries, not vexed, just get frustrated by all the laws which pretend to be about safety but which will have no effect whatsoever on safety ::)
Imp heads are easy - use coolant.
That's it! Back in the day, when they were brought out, only exotica used alloy engines (ignoring aircooled bikes!), so everyone put antifreeze in the cooling system in the winter and water in the summer... fine in a big old iron block... but without the corrosion inhibitors alloy furs up, the fur sweeps round to the thin pipework of the radiator and then stops!
Now the cooling is ok, just(!) An standard Imp with a half reasonable condition cooling system will run a little hot if you hold a steady 70-75 on the motorway (not far off top whack!) and is fine everywhere else (we've done 400+ miles fully loaded at 60-70mph with no probs), if the radiator is choked however :o, now if you take Joe Bloggs, he will try to continue driving his overheating Imp until it stops, by which time the head is probably warped ::) and of course it's not his fault for abusing/misusing it.. it's obviously the fault of the car.. ::)
On racing Imps they mostly fitted a front rad, and on high comp engines wills rings are the accepted mod, but the cooling system really is ok if you treat it properly, and the engine is a little gem ;D they used to be popular with hydroplane racers because you could run them up to 10,000rpm and they would hold together for several races before needing precautionary rebuilds. Little else would at that time ;)
Of course another attraction is that I could easily put a heater in the chair... ;D

I have seen one with a reliant engine fitted.If you want a Ural engine measured I have a mate with one,I could drop round and see him if you like.
If it's not a drama for you to do it could be very interesting... a quick measure (in the dark with a handy bit of stick so *not* accurate lol) puts the Imp engine at about 22" or 56cm, so not very long at all. Hmmm, obviously I'd need to find a way to connect the flywheel/clutch/bellhousing/gearbox... but in principle, not impossible.
Minus side is that it would need a bit of fabrication/engineering,
plus side is availability of engine (I've got one lying here!), smooth power (easier on transmission), comparable rev range (approx 6,000rpm redline from memory) reliability and as it does 80mph/45mpg dragging a car body I'd guess it should equal or better that hauling an outfit.... ???

Reliants were one of the first to use alloy engines in cars too,other than Rolls Royce !
They didnt suffer at all with warped heads or any other proplems.
And that is a loverly little engine.

I've seen Reliant and other car engines fitted,including diesels.
And the frame has been stretched to cope.
Then the clutch and flywheel is moded to mate up with the Russian G/box.
Beemer engines go straight in.
But again some modifications need to be done to the crankcases to mate up the G/box correctly.
Got all this and some more off Tim Berry who has now moved to Poland !
He was some big wig in the Cossack Owners Club and had Shit Loads of the things over many years.

Yeah, with the sober head on a 800 Beemer engine really is the sensible option. The mods to match it to the dnepr transmission are not too difficult and it solves the main problems all at the one go. Even can be described as a "very similar engine" when discussing it with insurers ;) ;D
Looks like I'm on the casual hunt for a complete BMW 800/850 airhead motor then :o
-
I work with a chap that races the Reliant engine in a formula 750 car. with some work you can get good power from them.

anyone know the front to back length of a bmw / ural engine? From front of the engine to the flywheel housing?
I have had a quick look at my Mates Ural.Allowing for the tape measure being bent around a bit the ural engine measures 32cm from the front to the join between the engine and gearbox.If there is anything else I can always go back as he only lives around the corner from me.

I'll think you'll find that its 750/800/900 or 1000 ::)
The 850 is and oil head :P
We all know that !
Go for post '81 800.Allegedly a nicer motor than the thou and unleaded of course.

We all know that !
And we all know manufacturers and modifiers so anywhere between about 750 and 850 *real* cc is probably possible :P
But yeah yeah, I'm not a boxer spotter ;) I'm told the 1000 breaks transmissions and the 650(?) has no more guts than the ural/dneiper type... so apparently the 800 is the one to have... however I suspect the trick will be finding a cheap one ???
-
A mate of mine has a Dneiper with a 800cc BMW engine which has been very reliable but he has had a lot of problems firstly with the clutch and then with the gearbox (that is the Dneiper gearbox).We went on it last year to a BSA rally in Holland no problems it would cruise at 70mph if you want more info please contact me as I have another mate who knows a hell of a lot about Dneipers etc.
-
Sounds just the job Bruce, I don't have your email tho... could you drop me a mail? My first question for now, I've possible got the option of either an MT9/10 box or an MT11 box, allowing I'll have to replace the bearings with proper ones anyway, is one type stronger than the other? I have a memory I was told MT11... ???

Yes ! I was with Tim at The Dragon Rally when we stopped by Diggers outfit and had a good chat.
Thats where Tim went into bit about how to mate the two together properly with extra lugs,spigots and dowls,to line the clutch up with the G/box.

In about two weeks I've got to move a mountain of gear for someone, including a Dnepr chassis with a Subaru engine :o
I'll take some piccies when I do it.

Have you seen the current bid for this non MoT'able piece of whimsy? :o
"I don't believe it!"
Is there Russian gold in the frame?
