It's not the final drive the fails, it's the driven spline in the rear wheel. Much easier to check and change than the final drive.

i bought it off a bloke who's brother had built the motor he had sadly passed away he was a bike mechanic .
the story i got from the bloke he had a 850g with a bad top end and a 1000g with gear problems so he machined the 850 cases to accept the 997 crank and over sized the cylinders as well as added a cam package. its stamped 850 on the bottom cases and 997cc on the cylinder. i did all the fab work on the cafe style

Goddamn, so it IS possible. I'd always made the assumption there simply wasn't the case room to accomodate the 1000 crank. IE, that it wouldn't be thick enough to allow machining without break-through or weakening it too much.
If the 1000G crank were known to drop straight in, then many folks would have done it by now. Obviously, it's not a straightforward mix'nmatch, like some other conversions, but it's not impossible. I think yours is the first I've heard of.
Over recent years, those who wanted bigger power and more grunt in an 850 bike would have easy access to the 1000G and 1100G engines, which just fit straight in, more or less.
