Hi Hugh,
I have the tuning catalouges and brochures, but not the sales brochure...Sorry!
I still think I'm right in the only difference being the bore size, this would include pistons, barrels and head gaskets it might be that they fitted a lightened crank but I don't know this for sure.
The close ratio gearbox IF it was fitted would be the same item that has been fitted to all SP 888's, sps 888's, all 748's and 916/996sps's. All the information I've seen/got says that the 916sp had a standard gear ratio cluster.
Which always suprised me, but maybe the factory thought the lower rev ceiling of the longer stroke bike didn't warrant the close box. The later 996's had bigger valves, stronger cases con,rods and also less agressive cams which would allow them to rev higher and withstand the extra stress.
