Re: Lower bevel gear spindle shimming - Darmah

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 ...

Re: Helloooo - another UK Darmah joining in

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 :tisk:
Enjoy the rebuild, hope to give You some relevant info if needed.

Re: Vee Two Hailwood Replica

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...

Re: Vee Two Hailwood Replica

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.

Re: head bracket factory numbers

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...

Re: Star stamp

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...

Re: GTL500 Los Angeles

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...

Re: Overflowing Carb

Is the seat of the needle tight and the little washerin good condition ? When it isn't tight, fuel can dribble past it and overfill the bowl. I recently read something of a float that wasn't freely moving all the way down to up. So that it got stuck when down and didn't close the fuelinlet. When it ...

Re: Drum Brake sprocket carrier re-assembly

Tom, Seems Harm and his crew discovered that the drawing was wrong but simply added the #28 without adding the bush itself. When You say the bearings have float, do You mean they are loose in the carrier ? If the bush is too short (or the carrier isn't machined correct) maybe that's why the outer be...

Re: Drum Brake sprocket carrier re-assembly

Easy to check : if it slides snugly over #28 AND is a tad longer than the distance between the two bearings in the carrier, it probably IS the "forgotten" distancepiece. Seems Gigi lost a spacer in his book ;) I know I have a few of those in my spare-parts-bin but they could also be some leftovers f...

Re: Darmah down under

1977 , Must have a low number then.
Pity about the original wheels and discs but now EBC floaters on the FPS wheels. Nice touch :-D
Starter probably dumped because the starterclutch went bad. Nothing that can't be fixed.
Conti 2-1 ?

Re: 860GTS into Darmah

The engine mounting holes are identical on all bevels. The difference is in the gearchange. The roundcase had the box on the right outside, shifting rightside. 860 had the square box on the right and a shaft from the left side to the rightside box, running outside the crankcase. The Darmah had the s...

Re: Ducati 900 SS '82 | Front cylinder exhaust running hot

Last winter after a cold damp night outside near the Waterfront, my Alazzurra didn't start like it used to. When I got it running I drove slowly the 4 km to the highway. While waiting at a trafficlight, I saw that my vertical exhaust was yellow (about the same as those smileys here on the right). Go...

Re: Cylinder base gasket - 900 bevels.

I never found any ally gaskets on any bevel (except for the singles for detuning).
Shimming on twins : getting the compression on both cylinders a bit more into the same range (Guido didn't always check that).
Could be that the bikes were handled in the past by the same mechanic.
