It could be a leak in the intake between carb and manifold/head. Didn't You mention cracked rubbers between manifold and head ? Or on some of the newer type manifolds : the rubber ring between manifold and head. The plastic bushing between carb and manifold that is split and doens't seal properly. c...

Just a distancepiece between the bearings.
Grease to keep it relative in place, as is the ring.

welcome in DucatiWonderLand.
The serial number look up CLEARLY stated ??
You mean like : info that came from Bologna ? where a lot of parts were mixed and matched ?
As long as the gearbox is working and correctly shimmed, enjoy it.
Nothing visible from the outside

The rim of the frontwheel looks like a 4777
If those are stainless steel spokes, they could be Original Moto Guzzi.
The 6bolt carriers are made by Grimeca to fit Guzzi and Ducati.
The discs are EBC floaters.
All in all a nice and working upgrade

You mean You want to replace the back downtube of a Darmah , the one that goes from the rear engineplate to the toprails ? WITH a dent, a bend AND the "modification" for a bigger battery ? Why not look for a old, damaged frame and cut out that part, so that You can use the engine (or a template) to ...

Inner covers are interchangeable : singles (4 or 5 speed) and paralleltwins. The latter also have the neutralswitchlug. The moving parts are also the same BUT there is a difference in some diameters of the shaft of the gearpedal. And off course the part that controls the fixation of the gears : 4 or...

If the 750 didn't have the hardware to fit a neutral switch, all parts of a 860 can be swapped and pronto : a 750 with neutral light that works.
Shouldn't be too difficult to come by ?

Due to the helicoidal teeth, the connecting gears are pushed outward (and upward), hence only shims #24 on the outside. Since the gear to the crank is a straight-toothed (?) one, there is no need for additional shimming. Don't want to make the shimming harder than it already is :shock: :shock: ciao ...

Usually the beer gets opened when all shims fall on the ground and the drive to continue fades
Just one, otherwise You may develope a drinking problem on top of the Ducati problem
Enjoy the rebuild, hope to give You some relevant info if needed.

The engines that were used in the endurance-racers weren't entirely build by Ducati but by NCR. They got unofficial help from factory-employees and engineers, but because they were a governement-steered factory, they weren't allowed to spend money on such capitalist things as racing. Hence NCR-Ducat...

Did VeeTwo recreate the engine, or are those of Ioannoni ? He has been building them for years.
Seeing the tacho going more than once over the 10K, I suspect there is a plainbearing crank in it.

Not entirely correct, at least about the part number. Verlicchi stamped the frames with partnumber DGM 123 860 SS * *, sent them over to Ducati and Guido at Ducati entered the REAL framenumber between the stars. So in a few countries in Europe only the sixdigit number was used on the documents. ciao...

Found those for a lot less money on several mostra scambio in Italy. Usually from eastern europe sellers. Aftermarket frames are available and could be replicated. I found that the welder at Verlicchi couldn't quite finish a particular weld and had a little fault in it, talking about S and SS frames...

I took all that stuff out, spotwelded the three holes of the bush and pronto.
Bigends get that tiny faction more oil

I guess You're Lucky : seems likt it is the second generation engine with the flat head. Previous the cylinders stuck out and fitted into the head (like the singles and v-twins) and were very hard to get gastight. Some suggestions for the saving of the engine : #1 Make a more sensible wiring harness...
