s2r 1000 compatable engine cases?

[DuciD03]

simple q - What other 1000 duc bike engine cases are compatible with s2r 1000 engine cases?

[Speeddog]

AFAIK: ST4S, S4R, M1000, ST3.

996, 998, 999 will have the same stud spacing for the cylinders, but will not have swingarm bearings in the cases.

(ha!... knowledgeable fellow ...)

ST4S, S4R, M1000, ST3 are the same as s2r 1k? ok ... this being the case .... so to speak ... inner case only, right? (I understand what your saying about the 996, 998, 999, thanks for that too ).

One question leads to another, this is where it gets less simple ....

What years ST4S, S4R, M1000, ST3? (s2r 1k was only made 2006 to 08, M1k 2003-05?)

looking at the inner cases the other day; the liquid cooled engines have hoses attached to the outer cases; so the question is ... where does the liquid run (it must run inside the cylinders; no, so therefore circulated through the cases). Without searching online ... are the  ST4S, S4R, M1000, ST3 liquid cooled? Is that the change?  The s2r 1000 series engine is the biggest oil cooled, before it goes into liquid cooled?.

[Speeddog]

ST4S, S4R, ST3 are liguid cooled motors, but all of that plumbing is outside of the main cases.

The only liquid inside the main cases is oil, and the passages for that are the same for all 3 engines.

AFAIK S2R1000 and M1000 are exactly the same motor.

I'm pretty sure the M1100 cases would interchange as well, but there may be some annoying details that prevent that.

[ducpainter]

On the 999 were the bearings in the swing arm like the SSS bikes?

Ok good this means I can widen my search for cases; but it's the unknown annoying details (to the uninitiated); that worry (us all I guess). Other relevant details appreciated ....

749/999 had bearings in the swingarm like 748/916/996/998/848/1098/1198/1199.

AFAIK, only SSS that has the bearings in the cases are S2R/S4R/S4Rs/S4Rt.

ut-oh (spagettios) did my case pool just get smaller?; 

so I cann't use ST4S & ST3 cases due to the bearing on the sss? or I sub a different matching swing arm  instead of the sss ... if I use ST4S & ST3 cases?

[Speeddog]

It's a bit confusing, yes.

S2R1000 is a 'large case' motor, so we'll restrict all compatible cases to 'large case' style.
S2R1000 is a 'swingarm bearings in the cases' motor, so we'll restrict all compatible cases to 'swingarm bearings in the cases' style.
S2R1000 is a '996 cylinder stud spacing' motor, so we'll restrict all compatible cases to '996 cylinder stud spacing' style.

So, the only cases that fit those restrictions are ST3, ST4S, S4R, S2R1000, M1000, and possibly M1100.

All 'small case' motors; 350, 400, 500, 600, 620, 650, 695, 696, 750, 800 are 'small case', thus excluded.
All SBK motors are 'swingarm bearings in the swingarm'; so 748, 916, 996, 998, 749, 999, 848, 1098, 1198, 1199, 1299 are excluded.
The only remaining motors are S4, S4R, S4Rs, S4Rt, ST2, ST3, ST4, ST4S, M900, S2R1000, M1000, M1100.

S4, ST2, ST4 and M900 are not '996 stud spacing'.
S4Rs and S4Rt are deep sump, so not compatible as I'm assuming you're keeping S2R1000 exhaust.

S4, S4R, S4Rs, S4Rt, ST2, ST3, ST4, ST4S, M900, S2R1000, M1000, and possibly M1100.

omg  wow lotsa detail there[bow_down]
yaaa its confusing (wtf!)

thanks (I think)
I'll have to re read er again when Im well rested.

....sweet duc dreams .... to all and to all a good night.

Just looked up s2r 1000 specs; this might be an error or it may not make a difference but one site specs a 992cc engine; is that correct? - sigh -

ok; yepers keep the stock pipes so no deep sump.

[Speeddog]

Yes, "1000' motor is 992cc, as is ST3.

But it's not an issue, as they're both '996 stud spacing' cases.

... ok - thanks! - again -

M1000 usually refers to Monster. MTS1000 or MTS1100 are Multistradas.

[Speeddog]

M1000 = multistrada right?

what about the other 1000's; like the sports classic and the GT

I mean Monster when I write M.

SportClassic and GT cases are interchangeable with other 1000's, AFAIK.
