Re: need identification help

it does have a black headlamp shell with the shocks and thee seat trim strips as described. Don't want to disappoint You but those things were fairly interchangeable and could've come from another bike/type. Main things are engine (wide or narrow), cylinder (8 fin 250, 9 fin 350, 10 fin 450 unless ...

Re: need identification help

The bike on the picture is a Widecase and by counting the fins (9) on the cylinder it is probably a 350.
That's about all I can tell from this pic, never really got into singles and/or the differences between US UK AUS and all European models.

Re: How do you tell a WIDECASE vs NARROWCASE single engine?

Hey Steve, while looking for another post I noticed a small mistake in Your first post.
The diameter of the rear bolts of a widecase is 10 mm, front 8 mm.
And indeed, better try to find 10. bolts to keep them from breaking .

Re: 750SS Big Ends

Just a few remarks. Racing puts a lot of stress on parts that weren't always designed to take those amounts of stress. I admit that to overtake one of my fellow competitors I didn't really mind going over 10K on my Darmah racebike. But it was fun staying with a 851 on the drive to Les Combes and out...

Re: 83 MHR top end rebuild - low compression pressures

I suppose You took good care of the seating of the valves, checking it with liquid in the chamber. And before fitting the heads, lapping them on the cylinder, making sure there's no debris left. Did You check compression with an electric start or kick ? And of course fully open gas ? When You say th...

Re: SmartCarb in 1976 900SS ?

A correct tuned Ducati isn't difficult to start. If it is, there's something not right. I used my SS and Darmah on a daily base, except with snow or freezing, and I didn't have to make a fool of myself after getting gas. It usually started first kick. Even my girlfriend (55 kg) could start it. ciao ...

Re: 860 gt Moving forks up 5mm in Triple Clamps??

I would be surprised if You notice anything, except Your exhaust grounding faster (because the weight gets more front-biased and the drop of about 2.5 mm in the middle of the bike). I would be surprised if You notice THAT :-D :-D So, go ahead, it won't hurt and at last You can have the (non)experien...

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...

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&q...
