2001 shouldn't have the hoop rear suspension either right?

So looks like some older favor of 900 in those first two shots - not a 2001.

You all have very sharp eyes I have been staring at these bikes for a week and reading forums and did not catch that it had a dry clutch! I found this page http://www.motorcycleinfo.co.uk/index.cfm?fa=contentGeneric.zvfiihryhlqbrzht&pageId=2255673
and if the section about "data stamped on engine" is correct then the engine is from a 96'.

Make sure the motor mount bosses on the engine aren't cracked or broken, that bike took a big hit on the front.

When you say motor mount bossed do you mean the front bolts holding the motor to the frame?

I double checked the sticker on the frame and the vin on the frame against the title and it's a 2001. I guess the previous owner dropped the guts of a 900 into this frame? Since I have the two motors, what are the big differences or advantages between air cooled and air/oil cooled?

The only '01 Monster without the hoop is the S4.

The motor mount bolts go through the engine, front and rear.  If the bolts are loose or the bike is in a crash the parts of the engine casting the bolts go through can crack.  Repair is possible, depending on severity.

Also, the mounting bolts on '01 and newer are 12mm, '00 and older 10mm.

the "00" motor is a 2001 year model.  All 1998 - 2000 small motors had green side covers, 2001 silver.  some minor differences, nothing really notable except for the clutch pushrod length.

ducati motors are labelled "air cooled" or "water cooled"  the euro engine numbers have ZDM (capacity) then A or W depending on cooling, 2 or 4 depending on valves per cylinder (later motors have dropped this), sometimes another letter for variant then the actual sequential number.  usa engine numbers are a bit different, although the last 6 numbers are the same sequence. 

i had a 2000 900SS apart recently and it had oil cooled cylinders.  not sure when they went back to that, as it was dropped from the 1998 900 motor when they went to the 3 phase alt.  you can see on the LH side of the 900 motor you have the two hoses from cylinders to alt cover - they're the oil return hoses.  1998 onward didn't have them, supposedly didn't need them.

the 2001 bike must have been a 600 or 750 and now has a 900 motor, as 900 was ie from 2000 onward.  looks like the inlet manifolds are still the 600 or 750 ones - 900 ones have a real step down in them as the cylinders are longer - but it could just be the way it looks in the photo.

As far as I can see the engine castings where the bolts go through are not showing signs of stress or cracking but I will give them a full inspection before we transplant the motor. The only thing on the engine that is damaged that I can see is the oil cooler mounting bracket and the vertical cylinder timing belt shroud. Thanks for the heads up about the mounting bolt diameters.

Thanks the the info about the side cover colors, that confirms what the engine stamp decoder said about the year. Also what you are saying is confirming what I decoder about the 900 motor. It said it was a 96' and your description points to that year range as well. You are well versed on your ducati motors!!!

Your mystery wet-clutched motor is a 600.  The 750's had oil coolers which this does not and the 900's had dry-clutches which this does not.

As far as your 900 motor goes, it's a 1992-1997 motor as it has the single-phase charging system. 

In 1998 Ducati put the 3-phase charging systems onto the 2V bikes and followed up a year later (1999) with the 3-phase charging systems on the 4V bikes.  (Unless you're talking ST2 in 1998 which was a 2V bike with a single-phase charging system but it had a radiator...)

Since I have the two motors, what are the big differences or advantages between air cooled and air/oil cooled?

The bigger displacement engines needed more cooling capacity - hence the oil coolers. So if you want to follow the 'bigger is better' model, take the air+oil cooled one.

cant wait to see what the finished monster will look like. "AHAM" clip on handle bars!

An update! A 2001 frame has been purchased. Will be here in a week or two. It has a salvage cert. So I will be getting my ducks in a row with receipts for when it comes time to title but it will be a huge cost savings over buying one with a clean title.

Question for the 1 and 3 phase savvy. I have an older 900 that should be single phase but its in a newer frame replacing a motor that was three phase(correct me please if that's wrong). Is it possible that the 900 was converted to three phase or is it more likely the single phase harness (rectifier and other necessary electrical doodads) was swapped with the motor? I would be more then happy to post picts of what would be necessary for the experts (Hopefully that's you the reader ) to decipher what kind electrical system I have, just let me know where to point the camera! 

I really appreciate all the feed back and helpful advise I am receiving!!!!

Not easy to convert the motor as the cranks are different.

It looks like you have the correct harness as the pics show the ignitor boxes behind the air cleaner and in front of the battery. The only 900 that was 3 phase and used ignitors was the first year fi motor If I'm remembering right, and that was either 99 or Y2K.

1998 900SS FE was three phase and carbed.

[Howie]

Just count the yellow wires coming out of the side cover.  Three wires = three phase.

[elyse]

good luck!!

to hook a single phase alt into a 3 phase bike you just don't have anything going to one of the regulator yellow inputs.  no other change required.  don't use flat spade terminals like the 3 phase connector though on a single phase system or they will burn out.  the bullet style terminals work well.

usa 990ss fe was 3 phase and carbed, 99 900m was 3 phase and carbed, not sure about 98.  probably was i guess, i'm sure the little motors in 98 were with the redesign.

all ie bikes run the ignition via the ecu.

I guess I thought wrong.
