B12-GSXR750M and dot head mix'n match

[vitesse]

Hi everyone, so a while back I bought a B12 engine really cheap but with all motormounts broken... I've got engine cases from a gsxr 1100m and since I 've just found a GSXF 750 engine with a Dot head I was thinking of transferring the internals of the B12 in the 1100m cases using the DOT head and use cams out of a gsxr750m...

Is this doable, is there any gain  (carbs would be the 38mm from the 750m)

Need your axpert advice of what is involved here.

Not sure on this one but aren't the gear box bearings different on the b12 and gsxr1100m?

output shaft bearings are different but its not a big issue to solve.

Nice was not 100% I could remember there was something different between the two

I think the 750m head is shim type so cams aren't right and dot heads had 36mm carbs so fitting 38s will be a squeeze, using the 750m inlet rubbers will need a fair bit of port matching to work.

Much more.  Katana Mangler has a ton of good info in there.  Search Frankenstein in the vault, that's how I found it.
