What would you do? 900 swap or 750 motor work?

No replacement for displacement!

Honestly, though, unless you're in love with your 750, I'm not sure I'd mess around with the $ in doing a motor swap with a 750. I'd just buy a more modern air-cooled Duc with FI. For the price of the engine plus the cost of your 750, you're already in the range of a FI 900 or an earlier 1000.

That's the problem; I am in love with my 750 Dark. It was my first Ducati, bought it when personal life was not going so great and that bike brought me out of my funk or maybe it was the crazy ducati community? Who knows.

I definitely see what you are saying about a new FI900 or 1000, but I just like that bike too much to part with it.

Makes sense now...that's quite a bit of work to the engine.

yeah it is.

JD is an engine guy, that's all he likes to really do.

Not to mention his labor rate is only 40$ an hour and charged by the 1/4 hour.

6k service (more like 8k), with timing belts is going to run me under 450$

That would cover half of your new 900 engine

gotta get that service done before I sell it; I won't sell a ducati that hasn't been properly maintained.

Monsterlover · September 15, 2009, 01:11:24 PM

In that case I would suggest servicing it after the 750 is out of the frame.

Easier to work on while it's on the bench. Could save you a little money.

Count up what you are looking to spend on the 750 motor. Then price a 900 engine vs. what you can get for the 750 engine on resale. Contact Chris at cacycleworks and find out the numbers he got out of a 900 with a good bit of work done to it. See what the price difference is. I am pretty sure that he achieved 104 hp from his 944 with some headwork as well.

The 104hp 900 motor was/is a 966 that's got an EASY $4,000 into it.

Try to find an 1100 DS from a wrecked Mulit or newer Monster 1100. I haven't seen one for sale in quite a while, but I would guess they would be around $2K. Would they fit in the 750 frame? I don't see why not, but I'm sure someone here knows for sure.

staying carby.

I have 39 FCR's which are fine on a 900 motor.

Don't want FI.

Travman · September 16, 2009, 04:13:19 AM

You can put carbs on the 1000 & 1100 DS engines. My local shop does it. They say the FCR 's offer quicker response than the fuel injection. I'm not sure of what size carbs would work best though. The 39 FCR's you currently have may work.

Monsterlover · September 16, 2009, 05:14:06 AM

What do they do to run the ignition system?

Well lets just say he doesnt have that much to spend. If he were going to spend about 1500-2000 then calculate around 800-100 to buy a 900 and then the rest of what he was going to spend + what he gets from the resale of the 750 engine and he will have more power from the 900 for the same cost and still have room to add more power at a later date.

mdriver · September 16, 2009, 08:43:04 AM

I'm in the same boat as you. Want more grunt and to stay carby. I decided to go with finding a 900. Partly because more displacement is better for a strong feeling low mid range. Partly for the least functional reason possible, the 944 is the most bad ass sounding Duc I've ever heard.
I'm looking forward to seeing what you end up with.

900 motor swap with a 944 kit installed
Bueller?

This would be my vote also.

My previous Duc was a mostly stock 92 900ss, that I sold about two years ago.

Last month I bought a 01 M900sie from the DMF flea market that just so happend to have a F by F big bore 944 kit in it. All I can say is WOW !

Night and day difference ! Loads of great usable power from just off idle with a mid range punch that makes me giggle. [moto]

I am very pleased with it so far, good luck in your decision.

Norm · September 17, 2009, 08:38:25 AM

No offence, but around here, fixing up a 750 would be considered polishing a turd. It's thought of as a girl's bike.
$1000 will get you a nice carb'd 900 on the used market and another $1000 will put a 944 kit on it.
