the parts catalogue shows the 1991 # applying to all carby ss, lots of monsters and all st2 as well, so that may widen your search.
from memory, it had a couple of small open end spanners, a plastic screwdriver handle with reversible bit, a couple of 90 degree hex keys, tube spark plug spanner. should have had something for the rear axle i would think, but don't recall now.
907 one would be different due to rear axle nut size?
know all wanker
