1000ds compatibility?

Okay a barrage of questions really, some of which I half know the answers, hence the asking.

Assuming I wanted to swap a M900ie engine with twin fork swinging arm, for a 1000ds engine, which ones would fit with the least aggro?

Do they have different arrangements for the swinging arm bearings in the M1000, S2R and multis?

Could the 1000ds engine be run on an early 900ie ECU? Maybe with a power commander?

If the 1000ds ECU is needed, can this be used without the associated clock binnacle, or are those needed to complete the brain?

Does the 1000 use different throttle bodies and injectors to the 900 or could the 900 stuff be used?

Exhaust would have to be changed, but what about the air cleaner box?

Just toying with the idea of a heart transplant, but it will probably turn out to be much more trouble than I want to go to. Interested to see what's involved.

Cheers.

And why not an 1100DS whilst you are at it?

Swing arm should be ok.

Good point, but I know even less about those than I do about the 1000.
So all the same questions as above really.

Thanks emzedder.
Yes reasonably helpful despite the usual folk guessing at the answers just for the sake of posting something, but hope indicated at the possibility of retaining the ECU and throttle bodies.

monster / ss engines - yes
multistrada / hypermotard - no (wrong swingarm bearings)
sport classic - don’t know

throttle bodies - will want to match ecu for manual fast-idle vs stepper motor (before/after ‘05 ... I think)

not sure about airbox or injectors

Been doing a lot of research on the 1000DS engine recently because of my 1000SSie purchase.

Slob is correct that the multi engine is different because of the single sided arm.

From what I've seen the Sport Classic uses the same engine as the 1000SSie DS, but parts for them appear to command a high price.

Thank you Rob and Simon.

I thought it was the case with the multi/hyper swinging arm bearings.

ECU/throttle bodies don't look insurmountable by the sound of it. I might keep an eye out for a motor.

Just thinking out loud (and torturing myself!).
I wonder if there is enough meat around the swinging arm boss on the Multi/Hyper engines to bore them out for bearings?

This is something that I would contrive to do with a complete engine using a line boring jig of some sort, yet to be designed.... Sounds easy in my head???

So it’s a Monster 1100S engine you need to keep the same swingarm fitment.

Hi, having done this one here's my thoughts. First Slob's engine facts are just that "facts". ECU - one important issue is the ignition timing which is retarded for the DS engines, the fueling will of course be different with early type flattened ecu's this could be over come with a powercommander as I think remapping these isn't normal practice/easy, I just happen to have a PC for early type ecu if you want it. Throttle bodies on early 1000's are the same as early 900ie ones but the potentiometer is different to suit the 5.9 type ecu, I also have a spare early type potentiometer if needed, which will fit but obviously requires setting up. I also have an exhaust. Airbox you could use either I think. If you use later air box you may need a battery/ecu/fuse box holder to bolt onto 1000 rocker box I have one of those too. Any help I can give don't hesitate to ask. Bitza

I had it good authority that the throttle body potentiometer shouldn't make a difference as the ecu will work ok with both types (linear and non-linear). What will change is the way you have to set them up when you tune the bike. You can't TPS reset an non-linear type otherwise you will never be able to get the factory setting back. They have to be set with a volt meter. Linear type tended to be fitted to the later type models though like 696/796 etc.

and another thing, DS ignition coils there are two types Beru ones encapsulated, relatively smallgenerally well designed , and the Magnet Marelli ones which are big heavy highly corrodable go-wrongable. The important thing is that they require different electrical connectors, and god knows where to get them from apart from an existing looms. Of course any mix & match approach is fraught with issues particularly getting hold of the necessary electrical connectors for the ECU & Dash. Going back to ignition timing, I did briefly consider mechanically altering the position of the crankshaft sensor's trigger position in order to retard the ign timing, but this will of course also retard the fuel injection. It is basically a can of worms, and the advice somebody gave me is very true, if you want a 1000DS variant get one don't try and build one, but sometimes you just have to do something really stupid?!&%**

Many thanks Mike for sharing your experience. That's worth much more than any secondhand info or guesses.
Thanks also for the offer bitz and pieces.
I've had the idea to upgrade to 1000 if anything terminal ever happened to the 900, for a long time, but I think you have confirmed to me that it's not just a simple two bolt engine swap.
I think I would go along with the idea of getting a M1000 or S2R rather than cobbling one up, and start fresh.
Besides dacs has offered me an old fridge motor... Sounds like the way forward..
