I was having some problems with my clutch and when I opened it, I saw some bits and pieces of clutch packs. I decided that instead of fixing it, I would just buy a 900 engine since I've read it's a bolt on installation since my bike is a 1997 M750.
I found two options:
Option A: 96 900SS with 18,430 miles on it. It just comes with the engine, transmission, and clutch and it is missing oil cooling lines, carbs, etc. The price is $800 but the catch is that when they got the bike, they had no key to test it out before disassembling it. The engine number is: LC4T032743
Option B: 96 M900 engine with 7,977. The same as the 900SS, it is just the engine, transmission, and clutch. Price is a tad cheaper: $750. That's the only information given on it.
So, a couple of questions:
1) Which is the better option?
2) How can I tell if they are W heads or V heads?
3) Will I be able to use my carbs, oil lines, etc or I would need to replace more things?
4) What's the difference between the M900 engine and the 900SS?
5) Is there a step by step guide since I can remove the engine but putting the new one might be a problem.
6) Anybody selling a 900 engine?

Not sure buying instead of fixing is the best option for you, however here are some answers:
2) there's a V or W stamped on the engine heads.
3) carbs need re-jetting (you can buy a kit from ca-cycleworks.com), oil lines *should* work.
4) the SS has the rear shock bolt up near the back of the vertical head, there *might* be some difference there. Otherwise they should be identical.
5) no but the engine is heavy as f*** so be sure you have plenty of space and help.
Between the two, I would choose the M900 engine: it's cheaper and has fewer miles. Whichever engine you get, you should also change belts, oil, and filter and check the valves.
Oh, and take lots of pics. They help when you can't figure where the f*** some part went. And they make for good laughs too! [cheeky]
Good luck,

Well, I've always wanted to do it but I just wanted an excuse. [cheeky]
As I've been reading through here, though, is that you can fit a M1000 engine. Now this gives me butterflies in my stomach. So with this recent discovery comes a new batch of questions (I swear they are my last):
Will an 06 S2R 1000 fit as a direct bolt on?
If so, to convert to carbs all I have to do is replace the intake manifolds? Or will I have to replace more parts?
I saw in a thread that it might have swingarm issues. Is it true for this engine also?
Though you can fit a 1000DS engine in, the only direct swap would be from the rather rare m1000, or from a 1000SS as the S2R bikes have the single sided swingarm and have milled engine cases to fit it.
So those are just my only options without wasting big $$$ on making the others fit, huh? Oh well, can't blame a guy for dreaming. [cheeky]
Thanks for the insight, my good man!
What about Sport Classic engines. I think those will fit.
There was another thread where this was addressed about a year ago. You might be able to find it. DuckStew knew the answer. I think he said any of the engines from the Monster or SC bikes would fit.

I believe this is the thread...
Re: Monster 1000 Engine compatibility (http://www.ducatimonsterforum.org/index.php?topic=46122.msg839888#msg839888)
Chris Kelly (CA Cycleworks) outlines the differences in the cases.
Blue, Thanks for finding that thread.
After re-reading that thread I can not quite tell if we can use the engines from the M1100 in the earlier frames. I don't need an engine right now, but I always assumed that if I needed another one in the future I could use a M1100 engine and take advantage of any incremental improvements like the slightly lighter weight due to the vacuum casting, any head flow improvements, and possibly better shifting if they refined the transmission.

You may be right on that.
Well, after seeing the prizes for the Sport Classic engines, I think I'll just be content with an M900 engine. Thank you all for your help!
I have a 98 M750 and swapped in a 95 900 SS engine. I waited for a 900 ss engine to come up on ebay for a reasonable price. Now days, most engines on ebay are not for bid but are at a high buy it now price. The swap itself went okay. I had several gremlins to trace down. One that you should know about is that the M750 intake manifold were too short for the 900 engine. So, try to get an engine with manifolds. My M750 has 41mm FCRs so the carbs are fine for the new engine. I don't know if M750 stock mikunis are the same size as those mounted on a 900. I now have the engine running but am dealing with a jetting issue. At 7000 rpm and 3/4 throttle the engine misses slightly. I'll try raising the needle again. If you go with the stock mikunis you might budget for a jet kit. PM me if I can help.
Any problem with fitting the 750 headers on the 900 engine?

Won't fit.

+1 I know first hand. Nor will SS headers even though they look like they should. You'll need 900 monster headers.
My M750 had a Sil full 2 into 1 system. I have had no problem mounting it to the 900 engine, but it was intended for use on a 900 engine and just happened to have enough versatility to work with the 750 engine. These little problems that we are pointing out, problems with carb jetting, intake manifolds, and headers can easily eat up the budget and patients of a do it yourself owner on a tight budget.
