700xx drive info

i was wondering if any of you guys with the new 700xx have taken a good look at the sprocket on the motor and how it is setup. i was wondering if honda just added like a gearbox to relocate the sprocket to the middle or if the cases are just completely different?? reason i ask is because i am currently putting an xr650r motor into a trx450r frame, but i wanted to know if it was possible to make the 700xx motor work even though i doubt it will. also i would like to know about the fuel injection system. does it seem as if it is like a throttle body where the carb should go with an injector in there, or is the injector inside the intake or somewhere else?? i am considering using the 700xx fuel injection system on the xr650r motor which i think should be possible.

if any of you guys have some pictures of these parts, or could take some for me i would really appreciated it, thanks alot.
