Just another picture of the dnepr, painted 2K primer and PU topcoat.

Engine in line with the frame to fit on the gearbox i assume.
It depends size of the engine, 2 cyl Hatz don't fit without stretch the frame.
Punsun 2 cyl V-shape wil probably fit.

2 month's ago I injured my foot badly. I sprain my left foot and couldn't walk anymore. So very little activity employed. Today I connected my clutchcable, it take a while because made some special pieces to fit the cable rigid. Next time I wil place a picture. While I tried to uncouple, my gearbox ...

I don't have any experience with the company, I think there isn't a standart conversionkit. The frame has to be elonguated bij aprox 20cm. You have to cut some pieces and weld in other pieces to get it right. The adaptor for the gearbox on the engine is a machined piece . This is not so easy to make...

The expansionvessel mounted on the bike.

I cal it an expansionvessel, but it is the same as an overflow tank.
The system is without any pressure. Why pressure the system? The hoses can leak when the pressure is to much.

The Daihatsu is watercooled. When water is going hot it expands. The vessel works as an resorvoir and the pressure escapes in the open air. One of the top nozzle]s is open , the other is for escaping air bubbles into the air catched at the highest point. The bottom nozzle is for filling the system.T...

The expansionvessel for coolingwater is almost ready.

Wiring is completed.
Watercooling is in progress.
Hard to find the right rubberhoses for the cooling.

I cut the rubber hoses out the enginecompartiment of some car's , the cars wil be shredded anyway.

Make some aluminium couplers and connect the hoses together.

Looking for an expansionvessel.

Building is in progress,
I am wiring the bike.

I have no pict. because electric wire's aren't that interesting.

I have to connect many thing's with an extra relays, the standart BMW shalters are to weak for the current of some part's.

It's a while ago I give an update.
The project is slown down.
I am wiring the bike, not an easy work like the old petrolbikes I wired in the past.

It seems to me as a fatigue failure. It started at the drilled hole. It doesn't need a heavy force, only an force with an alternating direction wil do the job.
Just a tiny deficiency wil start the proces.

There isn't any movement by Elsbet for a couple of years. The concept of vegoil was new years ago but overhauled also years ago. The cast iron pistonhead looks a novelty, I have never seen it before. I think it is never produced because there are many problems to solve using a divided piston, top ir...

For years it was a BMW injection, model not important. But it was a total disappointment having an R1100R. It wasn't developed completely. Many annoying things and even so many (bad) excuses from the dealer. My dreambike is max. 50 Hp, don/t need more. Very easy to maintain. No need for periodic rep...

Push up the rpm is possible but limited. The engine starts using much more fuel compare the power delivery. Small dieselengines best torque is about 1800-2200 rpm for some reason. So you have to put your energie in gearboxes and/or bigger chainwheels. You are showing a nice dieselengine to us. I was...

What a big engine. I can't hardly wait to see the bike finished.

That's a hell of bike.
Well done.

Thank you.
I am wiring some things but there is few space to mount relais and yhat sort of stuff.
Some of those little things are time consuming to get it right.

Nice engine, probably Chinees.
Enough power for a dieselbike.
There are 2 versions. Aircooles and watercooled engines.
The aircooled engines are noisy and not so good compare the watercooled engine's.
But I am not an expert, It's what I picket up .

Very nice motorbike. i like the colour to.

The dieselbike partly mounted together.
Those little things for finishing it right consumes costly time.

Thanks for your comments! Henk, any pictures of your bike? Would be nice to see! I found pictures of Locomotivebreaths bike, very nice! However my idea has all the time been to keep the bike looking as much a K-750 as possible, so I'll be keeping the original tank. I'll take the injector lines tomo...

Very good project. I to have used (partly) a Dnepr-frame , the rear. But building a total fifferent bike. I see you have cut the backside of a Dneprengine to fit the gearbox on the Punsun. That's a clever idea. The Punsung engine max rpm is about 3600, so take the highest gearing you can find. I am ...

Connection frame and steer.

I have (some time ago) dismantle the gearbox completely and build it together with new bearings and a 1:1 4the gear.
To get it right I bought a defect gearbox and cut it in half.See pict.
So I got the distance's of the gears right when fitted in the half cut gearbox. It's russian so nothing is sure.

The mudguard is suprisingly stiff compare to it's lightweight . It sure would save some kg.
On my bike it is pure to prevent excessive forces on the aluminium lugs. Lightweight is a bonus .

The lugs on the aluminium frontfork are to weak for a steel mudguard to my opinion. I use the fork of a BMW K100. It consists of 2 front legs each apart and connected in the crownplate. I suspect these came from a type with integrated mudguard instead of a mudgard mounted on the frontfork. I have an...

Hi Dougy, thanks for the positive reaction. Nothing goes easy, while I place the pict. I remember the hard labour it cost's. Here a pict from an self made tool to dismantle a rear shockbraker. It is rough but I don't believe I will use this tool very much. After repair the shockbrakers I painted the...

Yes, is was a solid disk alumnium. I bought it in Germany (internet) and they shipped it to my home. Lucky we have a big lathe at the maintanance department. For a few apple-cakes they made the flange. Another pict from the fuel-tank. The red primer is very thick and sticky. It's like a tough sirup....

Fitting the engine in the frame. Every step is a lot of work. I blasted the frame with glass and painted with 2pack industrial primer, after the primer I painted theframe with black 2pack polyurethane topcoat. The topcoat is only for spraying. But painting with a brush is possible but not so smooth....
