A packet of allen wrenches, a sparkplug socket (do a forum search for this, most standard ones won't work) a ratchet and 3 or 4 inch extension, a regular size interchangable tip screwdriver, a small screwdriver for tweeking the carbuettors to allow for altitude changes and wrenches for adjusting the chain.
I also carry a can of chain spray and a quart of cheap 20W-50 oil in case I feel sorry for a Harley oe leadwing rider on the side of the road.
The phone that usually stays switched off in my pocket and my AAA (RAC in the UK) card cover everything else.
