Air cooler cylinders on water cooled cases?

I've got an S2R1000 head gasket and 1098 cases here, gasket will not fit over studs.
From the part numbers above, it will not fit 848 either.

That S2R1000 head gasket will not fit a 748 cylinder either.

I suspect the 1100Evo will fit 848/1098 cases.

Well the Evo and S2r use different top ends due to the dual spark heads. So it wouldn't surprise me the case studs being in a different orientation.

Interesting that the 848 & the 1098 use the same base gasket, I had heard that the 1098 got wider stud spacing than the 848 for the larger bore.  I will have to double check my part numbers but I think my test base gasket is the 786.1.114.1A Evo gasket.
The deep sump case is not a huge loss to me on this bike, though I do like the piston squirters that the 848 cases have.  I was mainly looking to see if I could use internal oiling to the cylinder heads if I switched to the 848 cases as the 749 does not have passages.

Another update with more information;
The base gaskets I was using for test fitting were 1100 EVO base gaskets so the EVO does use the same stud spacing as the 1x00 DS & the 749.
I contacted Duc shop as they are semi local asking if they had done any conversions on 848 cases & if they would be willing to preform the work.  They said that the studs can not be moved & shops that are preforming this conversion are elongating the holes in the cylinders & heads to match up with the botom end.  They do not recomend doing this, I can see how it could creat many issues when trying to get the cylinders centered & sealed.
So my hopes of having deep sump oiling & piston cooling jets may be over.

are the 749 and 999 the same cases?

I am not 100% sure if they are the same. I know 999 cylinders can be put on 749 cases with some modifications for a bore increase.  They do look to have the same issue as the 749 in that they use external oiling to the cylinder heads.  I am still looking into options of a cam bearing plate with enough material to add an oil port to, or drilling the cases for oiling as the locating dowl is in the same location as the oil spigot on the engines with internal oiling.

Base gaskets:

'05 999 - 786.1.087.1A
'05 749 - 786.1.087.1A

It may be necessary to bore the 749 cases to allow fitment of 999 cylinders, but same base gasket means same stud spacing.

AFAIK, the 749 cases have oil jets, they're just not the same as the 848/1*98 ones.

are the 749 and 999 the same cases?

Yes, the 749 & 999 base gaskets do interchange.
