Ducati Monster Forum

Yes, I have one lying around. I don't have my monster, yet. But I was just wondering if anyone had done that. One caveat- the 900ss is fuel injected, and the Monster motor is carbed. Am I just asking for trouble?

The 900SS motor should have carbs too...

+1...SS was first injected in 99.

You can tell the injected Supersports cuz they got all ugly  ;)

did not... :P

I like the Terblanche SS...and it's a much better track bike. ;)

I guess 'cos of all of the noises the SS made when I would turn the key I assumed it was FI...

Now I feel like an idiot... :-[

This info is why I decided to ask y'all.

1995 SS900's had a low-pressure electric in-tank pump that sounds like a high pressure pump so maybe that's where you were confused.

As far as the swap goes, here's the skinny:

The '95 will have 10mm engine mounting bolts same as the 1993 to 2000 Monsters do.  In 2001, Ducati made the change to 12mm bolts.
You can use the intake manifolds from the SS900 and the carbs too.
Monster 750 fuel pump will work w/a 900 engine so you're good there too.
Monster air-box will work too.
Monster 750 has a 4.5" rear wheel w/a 17mm rear axle up to & including 2001 so if you can score the '95 SS900 rear wheel it'll swap onto the Monster chassis.  If not (no rear wheel), then you'll have to flip over the front sprocket so it will be closer to lining up w/the rear on the 4.5" wheel.  (checking alignment is recommended w/any engine swap).
'95 had a single phase charging system (two yellow wires out of the LH engine cover).  2000 M750 had a 3 phase charging system (3 yellow wires going into the regulator).  Simply connect the two out of the '95 alternator to *ANY* two of the 3 on the regulator and you're good.

You *WILL* need a Monster 900 header as they're different than the SS900's.  If you can cut/weld or have it done, perhaps someone could re-do the SS900 header for you.

Duck Stew-

This is sounding better and better. I DO have the rear wheel. I actually have BOTH wheels with new Michelin Pilot rubber. It will fit in the Monster swingarm?

Now- something in the charging system was all f***ed up with the 900ss (the battery would dump). Can I use the Monster charging system?

I will probably have a mechanic help me significantly. While I have been doing some of my own wrenching when it comes to things like mods, I am a newbie when it comes to actually working on motors and such. But I think with some help, I could swing this.

Thanks in advance for your help!!!

Chances are the regulator is bad on the SS.

The crankshaft is different on the 2 and 3 phase motors so you can't swap components.

So then I should source a new regulator?

Maybe this could be my winter project...

They aren't that hard to come by. You can get an aftermarket unit in the $100 range. Electrex and Rick's are two brands I'm familiar with. I've had a Rick's in mine for years.

I think I'd make the swap and get the thing running so you can diagnose the problem properly before I started buying parts.

If you check in tech or do a search there are some threads about testing the various charging system parts. You could do the bench stuff up front.

Me thinks this is a winter project...

If the paint weren't stained on the wheels from the 900ss, I would keep them yellow. I don't know if the front would clear the fender (because of the slightly bigger tyre). Now I wish I would have kept a few more of the parts from the 900ss...

The front wheel from the SS will be fine.

Cool- now onto the fender question... (different thread)

Nope.  Ducati changed to a 25mm front axle for the 2000 - 2008 Monsters.  1993-1999 Monsters had the 20mm axle same as the SS's from 1993 - 1998.

If you test and find that you do need a stator (charging alternator) I have one available in the Parts For Sale section...  Just sayin'... 

damn...forgot about the axle...sorry

So then I would have a mis-matched set of wheels. Well, the design is the same, anyways...

I guess I need to start testing some parts...

Rearsets mount onto the engine, right? That means I am going to have to get some rearsets, as I know the Monster ones won't fit. Maybe the 900ss engine will have to go bye-bye, as this could just be the beginning of a never-finished project/money pit. :-\

rearsets mount to the frame.

Now I am an idiot... I can just drop this engine into the frame and basically have everything I need mount up with little fuss?  Yes, I am asking the question again because I want to make certain this is what I want to do.
I don't mind doing a little extra work, but if I have to fabricate stuff and deal with mis-matched parts, I may end up with another unridable mess!!! That's what the Kawa turned into...

The motor will drop right in. The motor mount bolt size is different, but you can open up the cases on the 900.

You will need the 900 carbs as there are some minor differences in them between 750 and 900 aside from jetting.

You will also need to fix the 900 charging system as the parts won't swap.

The rear wheel from the SS will bolt right on using all the pieces from the SS.

This really shouldn't be too big of a deal.

Keep in mind if the 900 has been sitting you may have some issues related to any engine sitting. You will definitely need to put fresh belts on the 900

It has sat for about three months.

Yeah- it could probably use a good going over, anyways...

3 months isn't bad.

If your belts are more than 2 years old you need new ones.

Can I use the swingarm from the Monster or do I have to source a 900ss one?

Just swap the motor and rear wheel/sprocket carrier and be happy.

An SS swingarm won't fit a monster frame because of the shock linkage.

The swap you're doing is really very simple. Try not to over think it. ;)

2000 Monsters have 10mm engine mounting bolts same as the 1995 SS did.  In 2001, Ducati went to the 12mm ones. Humorless dp is right about the rest of his comments.  ;)

I misread your earlier post about the bolts Stu...

glad you're around to point me straight.

Okay- you've convinced me. I may even try it sooner than later...

Any hints on swapping out the belts? Is there a section on this forum for doing that?

tutorial section..................even a link to a video.

Bear with me- I am a bit slow on the uptake :P

Thanks again!!!

One last question:

Do I have to use the wiring harness from the 900SS? The reason why I ask is 'cos it's kinda messed up. What electrical components can I use from the Monster for this conversion? DO I use the coils from the 900SS or the Monster? Again, I am a babe in the woods, so I appreciate your patience.

Use the Monster harness. It will fit the bike better. Most of the stuff is the same although you may have to do a little something because you're going backwards to a two phase charging system. Stu can probably point you on that.

All the peripherals like coils and ignitor boxes should work from either bike. You should use the Monster airbox etc...

Really...just swap the motor and put a 2 phase regulator in it and it should be fine.
