ducati 900sd in boxes

I have hesitated to start the thread until i have build pics, but what the hell right? at this point it would be pictures of cardboard as its all in boxes.

I have purchased a 78 ducati 900sd: mostly complete and original.. but in many boxes. I am picking up an engine stand in 4 days and the first order of business is rebuilding the (heavily shimmed) engine.

I have done some honda engines, but this will be my first ducati rebuild. I have received warnings that its a whole new ballgame in terms of precision in machining - in that ducati was slightly behind honda.
I tried to post some pics- even if its just boxes - but flickr has become such a pain in the ass recently that I need to find a different host.

there! made it work. ok, so that is not my garage. that is the garage of the of the guy who sold it to me. but that is the bike, the engine is in that pile in the back. its pretty complete - with the exception of the headlight rim- which i hear is the same as an airhead- so should be easy to find.

There are shims everywhere in this engine. Especially the bevel drives. Some as thin as .001". Do not mix the shims up as you will not get them back in their proper order. If this is a desmo motor you can upgrade the opening rockers to a later slide over rocker. Makes the valve adjustments easier.

Ducati was really just a shim maker back then, they only built bikes to have a market for them

The good news is you won't need an impact driver with a JIS tip to get it apart.

Well, ok, it sounds like it's already apart. But still...

The headlight rim is more likely the same as a Guzzi.
Take note of what folks are saying about not mixing up the shims.An airline pilot in Louisville bought a 900SS bevel drive and wanted it perfect ,so he took it apart and cleaned each piece til it was spotless. Incuding the shims,but he put the clean shims in a bag. All of them in the same bag !
Then he started a tour of Ducati dealers to find someone who could sort it out. Jon White turned him down and told him the only one he knew of that might put in the time and do it. was D.. D..... I left his name out on purpose,He's not working on much anymore.
D.. did sort out the guys motor for him and he said "I charged him plenty, too." And he told the pilot ,if he found anymore he wanted rebuilt , just bring it in one piece.

probably the same as those as well. I have a /6 and it looks just the same but I have not tried to swap it on. Same stupid clip system that fails and drops your headlight on your fender. great... like I needed another one of those.

zip ties are your friend.

You my friend are a brave man taking on a bevel drive Ducati. I too once fell for the charms of a fiery Italian temptress only to have all my love and affection thrown back in my face. I left the relationship a penniless and broken man.
You have yet to experience the fusebox with the cover that falls off that's mounted above the short sexy front mudguard and catches all the rain. The starter motor sprag clutch that fails when your furthest from home and really need to be back. Magnesium wheels that dissolve and cost a kings ransom to replace...the list goes on.

Take it back, get your money back and pretend you never saw it

Don't forget the big ends usually fall out at 20k and the crank needs to be shimmed up.

Shit, if getting classics back on the road was easy, every dickhead would be on one. This way it separates the MEN from the boys.

That's why new bikes are like appliances, so the boys can ride too

That's easy to say from the comfort of your nice warm computer chair. At the side of the road on a dark, wet night miles from anywhere I wonder if you'd have the same bravado

This was mine. As you can see the front wheel had started to dissolve. The rear went shortly after. They're $3000 a pair. http://www.bikehps.com/acatalog/Marv..._wcB#aMCAMPDUC

I can say I've only been stranded twice by one of my classics.

Honda 750 ignition switch gave up the ghost but I jumpered around it with a piece of wire I had in my tool kit for just such an emergency.

Triumph Trophy just quit once for no apparent reason. Would not start until the next day then it has run fine since for around 5 years now. I think it was just tired.

My new bikes have left me stranded more often and worse off than my old ones.

Its really easy with Italian Bikes - think of them as women,
There looks will seduce you, you ride them like there is not another day left, they never make sense and you will never understand them and by god will they strip your wallet bare.


But still can't keep away from them - its a bloke thing.
