Re: Smoking under acceleration.

So the exhaust guides were changed for the later ones and the inlet stayed the old (inner o-ring) type. I remember fitting new o-rings in those guides, only to find a tiny piece of it coming out of the guide when I pushed the valve through. Not the top of the valve but the cutout that houses the two...

Re: Smoking under acceleration.

Perhaps drilling the drains to (IIRC) 10 mm instead of 8 mm (don't forget the dowels) would increase the draining and solve the problem. Did a previous owner use some RS bearings on the camshaft-bevel side ? that could prevent/decrease oil flowing to the bevels and raising the level in the head. You...

Re: New owner 860 minimum rec. Rpms

I found a few bigends of 450's that were clearly damaged by severe knocking or low revving full throtlle( damaged high up the bore of the bigend). On 350's (used here in a one-make singles Ducati class) most were damaged by high revving (damaged low and piston touching head). The roundcase twins had...

As long as You don't use the fins up front, they could break. Don't ask.

Re: Left Hand Switch Block

Since the Italians are known for their constant use of the horn (Lhand switch), Ducati fitted the pin to prevent twisting. Nothing to do with the throttle :shock: :shock: ;) ciao ducadini And indeed, grind that thing away, chances of getting that hole drilled first time on the correct place are abou...

Re: S2 rear footpeg: what thread?

As I remember reading in an article : Ducati sent a GT to the States to evaluate the bike. One of the (Berliners ?) remarks was about the rear footrest. They were changed on site and the bike was sent back to Italy. There Ducati just copied what was changed, including the (for Italian standards) thr...

Re: G’day from Australia

You won't be the first to have decided to abandon them in favour of something more practical. And enjoyable, frankly. Really Craig, "something more practical" ? A Bevel ? But don't let this discourage You Cyberduke, just a personal point of view. And ironically my '94 SS and '01 750 are the better ...

Re: Pops out of 4th gear

Fourth gear is the direct connection between inshaft and outshaft. Is that engine VERY recently dismantled ? then probably the shimming of BOTH shafts (and of course the selectorshaft) was neglected. When shimming the clutch must be fitted (or a suitable substitute) and the sprocket (also or substit...

Re: SSD having trouble getting into neutral while engine running

Another thing You can do, while the clutchcover is off to check Craig's points, is see how the clutch pressure plate lifts. Sometimes some of the springs don't have the same force (anymore) and tilts the pressureplate, still engaging on one side creating drag and making it difficult (or impossible) ...

Re: Greetings from Ireland

Looks like a 1980 500 (to start with) because it has the oldstyle fairing.
There WAS a defective batch Speedlines, but they were also used on the 500 SD without (as far as I know) breaking.
Better let them xray.

Re: How to re-install top fork nut on 1975 860GT?

Taking the spring out of the tube, and with just the forknut finding the right spot for the "click". Mark the position of the nut (with a marker ;) ), put spring back in, with the nut just a tad back, You don't have to search for the start of the thread.

Re: 860GT LED headlamp retrofit: attempt 1

But did it improve riding in the dark ? I have the impression that 2 ordinary 6€ LED flashlights give me more light then the H4 in my 600SS. The last 3 miles are on a non-lit road with trees (and dropping branches). I don't really need more light (a few weeks before retirement) and I don't like tour...

Re: 900ss clocks?

Yes, those Veglia clocks have been used on the SD500 and SD350 paralleltwins :-D :-D
As if those are easier to find :roll:
Veglia (now Veglia Borletti) is still around, not making those clocks, but those Ducati stamped ones are getting difficult to find (working).

I think those are still available , except for the alu tops : keep them.
Carefully change (if needed) the injector plastics.
