Hi , nooby here .
I recently picked up a "barn find" '91 851 . It has been sitting for a minimum of 10 years in a storage facility . I have been in the industry for 30 plus years and owned my own independant repair shop for 10 years prior to selling up and retiring at the end of 2016 and moving to New Mexico . However i rarely had Ducatis thu my shop for anything other than tyres , brakes , chain and sprockets or oil and filter changes . Consequently i'm a little in the dark with bringing one back from the dead . It has 16080 genuine miles . Last service was at 14750 when it had a major service with valve adjust and belt replacement . I plan on replacing the belts again since they are 10 years old and probably hard/deteriated . Also the usual oil, filter , plugs , clutch and brake system overhaul , chain and sprockets , fork rebuild as they started weeping on the 700 mile trip home in the back of my truck . . The tyres are original Dunlop Sportmax , both dated 08/89 .
I'm hoping i can get some insight into what to look out for , any advise would be greatly appreciated .
Cheers .

Nice find, looks very good for a barn find !
You have a model 92`, the last year of the 851.

Yep, 1992. Welcome.
Looks familiar... I'm in the same boat as you; 1992, 16k, stored for long time, Sportmax tires, etc...
I've done some head work and will be having the frame painted now that I have a Abba stand to hold everything else securely.
Keep up posted on the progress.

IMO the '92 851 is one of the best . The '92 has the newer 888 style body work, newer curved radiator, newer style valve shims, white frame with top cross brace, etc. I would replace all of the fuel hoses (even inside the fuel tank), fuel filter. Get hose that is for immersion (ebay is a good place tolook). The only drawback of the '92 is it has a Showa shock (others have an Ohlins). It still has the P7 ECU (P8 came in '93). Great bike ! (I have one as well)
p.s. You can buy a OEM filter from Ducati if you want to but I would buy a NAPA #3032 for 3 bucks.
2nd p.s. A good source for parts if you don't have a Ducati Dealership close to you is ducatiomaha.com However their parts diagrams don't go back very far so you will have to have a part number. This Forum has lots of information in the files section.

I think you've about got it. If it was me I'd do the fuel pump and all lines just to be on the safe side. Perhaps radiator hoses too depending on your budget.
Great find, get cracking on it

I would get the fuel injectors/regulator and fuel pump checked out. If it was standing with fuel in the tank , don,t forget your bike has the metal tank. Fill with water and check for leaks.......maybe even get it coated on the inside just to be sure.
I like the wooden bike stand...........I might make one myself just to raise the bike up a bit.
Lovely looking bike with the white decals and frame.

Well i drained the oil overnight , as well as removing the oil screen and filter . Next day i replenished the engine with Shell 4T full synthetic 15w50 and factory filter . I was going to use the NAPA alternative but it wasn't available here in Albuquerque , New Mexico . More on that later . I flushed the front and rear brake systems and clutch hydraulics with new dot4 , bled and good to go .
I called the local Ducati dealer enquiring on timing belt prices and cost of replacement and was told without hesitation that they would not work on my bike as it was more than 10 years old and no parts were available ! . Now , i kinda get that . In SoCal where i had my own independant repair shop for many years that was the common mantra of the OEM dealers - and i got a lot of work because of that attitude . But that is designed to keep away the beaters that have had multiple owners , been crashed and poorly repaired or are just old and have soft phillips head screws that shear/round of when you try and remove them , plus other reasons that we all know . The dealers do not want responsibilty . I was just suprised that a Ducati dealer in a small city like Albuquerque could afford to turn away work , especially as the bike is low mileage , unsullied and in good condition . Then again , after visiting the dealership and noting nothing but the latest and shiniest new Ducatis in the new Honda/Ducati showroom - do i want a fresh MMA grad working on my bike when he has no concept of its lineage or place in history. I think not .
So i rummaged thru my tool box and found my old Ducati tools which i thought i'd sold with my shop , must be spares , and decided to put away my lazyness and do the job myself . I ordered new belts and spark plugs on line , ($36 a piece for plugs at the dealer here !! - not in stock of course - not even alternatives). I need to pick up a battery which i'll get from the Yamaha dealer as it's the same as a V-Max but costs half as much as a Ducati part #. I also need to order submersable fuel lines as advised . I should probably ultrasonic the injector bodies and fuel pump too .
I was a little concerned the motor may be "stuck" after sitting for 10 years but i was pleasantly suprised when after pulling the plugs and putting it in top and turning the rear wheel it turned over as smooth as silk .Stuck my thumb down the plug cavity and plenty of squeeze even turning the wheel by hand .
So gotta wait now for parts to arrive .....

Plus i'll check the electrics after i get it running . I shone a flashlight into the tank and its as good as new suprisingly . Good call @dudlington .
The workbench is a boon frankly . I'm too old to work on the floor but i didn't want it so high i couldn,t reach stuff or push a bike up on my own . It's 8' long and 2' wide . The legs are 18" to the underside of the table . Works great . I'm 6'2".

I don't think your local dealer knows much. And yes, the youngsters know nothing of the older bikes! Belts are still available. Probably they looked at the old part number (before the red label kevlar belts) and just gave up. If nothing else, Calif. cycleworks has "Exact fit" belts. Made in China but everyone says they are OK. I have always used OEM Gates belts personally.
Yes, do it yourself if you can and do it the way it should be done!!
p.s. Sounds like your NAPA is seriously lacking. My local NAPA , if they don't have it, will have it by 8:00 AM the next morning 99.9% of the time. For plugs I use NGK equivelent (I like NGK better than Champion ayway)
macsport44
Well i replaced the belts with EXACT FIT belts and probably just as well as the old ones , tho low mileage were stiff and and hard compared to the new ones . I must have had one too many adult gatorades when i checked the gas tank because once fully drained it is full of rust and sediment . I'm farming the tank cleaning and sealing out to a local independant shop that has come highly recommended . The wife is not keen about the bad gas smell wafting over to the house .
I bought a new NAPA fuel filter , new gas cap base plate "o" ring and top seal ( 2 each - i understand they are easy to mess up ) and will have them replace everything including all fuel lines inside and outside the tank . The fuel pump doesn't work with power applied so i bought a pump from ebay that is a replacement for BMW K75/100' . It said it's for 851/888 Ducatis also . Anybody have a better alternative ?.
Interestingly enough there a few older ducatisti here in Albuquerque who are passionate about the brand . I met an older guy - like i'm not old @ 62 lol - who has 4-5 older ducatis , at a giro restaurant !. He makes the most beautiful Ducati belt buckles - has restored many old Ducks to boot . I think his name is Tom Rolland .

You maybe able to resurrect that pump. Fill it with injector cleaner , let it sit for a while or overnight. Then try it. sometimes you have to connect it in reverse so it runs backwards and breaks it loose. Once it's working again run injector cleaner through it.

I have run into a little problem . The tank cleaning and lining i outsourced to a local reputable shop . It has taken a while but is all done and going back together . I asked them to install the pump i bought on ebay along with all new fuel lines inside and out and then run it . If all was well i was going to have them replace the tyres before i picked it up . Unfortunately the generic pump i bought on ebay doesn't fit the clamp inside the tank . They do not want to mickey mouse it and have asked me to get an oem pump . I am having trouble sourcing a pump that is of the correct specs but also the correct dimensions . Any advice ?.
Cheers .

I should have mentioned that the old pump is/was completely junk - beyond fixing .

The fuel pump and mount for the Ducati 851 1991 an earlier is the same as the BMW K75/K100. Ducati changed the pump and mount (DUCATI # 82910771A, it will be moulded into the rubber mount) on the 1992 851 and later 888.
You can still purchase the mount from Ducati (the new number is 82910772A) if yours has come apart, and I think that there are some old threads on which pump to use. The 1991 and earlier bikes use a large 52 mm Bosch pump. I think that the later bikes use a Walbro pump, which is smaller in diameter than the Bosch pump).
Supposedly this Bosch pump will fit:Bosch 69238 . It is cheap on Amazon, but you should do some research to make sure that it will fit.
brad black
0580464998 is the bosch number
Foggy 888
Brad, the Bosch 0580464998 pump is the large 52mm OD pump, which fits the 1991 and earlier bikes. The 1992 851 and later 888 use a smaller pump, Walbro AOU195.
brad black
ok, i thought i was helping. sorry.
macsport44
Actually everyone is helping thanks 😄😄 . Seems the Walbro pump is available but not here in the States from Amazon or Ebay . The Bosch equivalent is available but nowhwere can i find the specs for it , like GPH or pressure . Following threads on it takes me to all kinds of auto forums and nobody seems to know . I'm leary of that in a way because i bought on Ebay this week a replacement water filter for my fridge - supposedly a direct replacement alternative - and it doesn't get within a bull's roar of fitting !.
So i'm faced with a mortgage payment for OEM from my local dealer who doesn't know shit from chewed dates , Walbro for $85 from Bulgaria or Bosch for 1/2 that here in the USA but with unknown specs . Think i'll roll the dice on the Bosch . It's a project anyway .
If anyone wants the 52mm pump i bought it's yours for $20 shipped .
Foggy 888
The Bosch pump should work fine. I am sure that it will have enough output and the pressure is controlled by the Ducati pressure regulator.
Did you see the thread started by Stiglarsen? He is using a Bosch pump in place of the original Walbro. You might ask him which Bosch pump he is using

The little pump used on later models is used by about 8 billion cars. They come in different overall lengths and with different plugs. If you take it to a general auto shop(NAPA?) they rangefrom $60-120 here in Aus, so about 20cents in the US. 😁, i'm sure you'll find one the right size. I used an MX5 one and just stuck on a plug. Then the x trail did in a pump and surprise same pump. There all about 5 bar pumps and as mentioned the pressure reg dumps of the excess pressure.
