Re: 860GT runs rich --- try smaller pilot????

It could well be that the Darmah 900 has a #55 pilot, but I thought we were talking about a 860 GT ? :shock:
Well, nobody forces You not to try something that is easy do fix and could give results.

Re: 860GT runs rich --- try smaller pilot????

Dell'Orto doens't just make carbs for Ducati :shock: ? They've been busy for some time now and tried (not always succeeded) to keep things uniform, like pilot jets, usable in a wide variety of carbs. And needles, also of different tapers, lengths and thickness. Maybe the needle in Your carbs is just...

Re: 1975 860GT side cover screw search

My daughter is getting married this weekend, so I'm grounded from motorcycles :oops: :oops: . The governement (NOT MY governement) is thinking about a total lockdown (again) and this will be decided this weekend. I can dodge that and next week go directly to CentralAuto and Fabory (20 miles away) to...

Re: 1975 860GT side cover screw search

It shouldn't be to difficult turning those square thingies away but I understand Your hesitation to make the cut in the head. So on went the search and I found them quickly on three places, two nearby (Central Auto and Fabory) and one in Italy (I wondered where Ducati would buy : just down the road ...

Re: 1975 860GT side cover screw search

Had nothing better to do so went for a hunt :-D Found seven of them, used (and some abused) of which two complete. Also found that bolts DIN603 (or ISO8677 and available in Stainless) have nearly the same head as the Ducati screws and are available in M6 x 45 mm (just a tad longer). The head has a d...

Re: 1975 860GT side cover screw search

Cleaning garage and getting rid of "stuff" but stumbled on 2 of those. I suppose there must be more of them somewhere.
Don't know about the shape and can't recall if they had the rubber bushing on.
I'll let You know.

Re: Why Are Modern Motorcycles so UGLY??

Probably because I've forgotten what I did on my 60th birthday, I tend to agree and the europeans were a bit influenced (and hence went in the Nippon direction). Still don't like all those superenduros and naked bikes, even the Ducatis. I think one of the last beautifull bikes (not "just nice" but r...

Re: SmartCarb in 1976 900SS ?

The starting procedure as 81mhr uses is about the best You can follow for nondestructive starting :-D May I just add this : while slowly kicking the bike (after the clutch is freed) to compression, I'd listen to the front carb hissing. The rear is compressing, the front is sucking. When You kick, fr...

Re: 860 Old Engine periodic head re-torque ??

I have an exhaust wrench--I don't think safety wire holes have been drilled in the adjacent fins.
There should be four holes drilled between the fins so no need for drilling extra.
Maybe in the head or cylinder or valvecover.
Good enough for wiring the nut.

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.
