Ok, putting this all together and making my own substitutions/additions, this is what a full tool bag calls for...
3/8" ratchet with extensions and sockets ( 10, 12, and 14mm)
a spark plug socket w/ 3/8” handle slot
combination wrenches (9 thru 14mm)
an adjustable wrench
a pair of vice grips
a pair of cutting pliers
a medium size pair of water pump pliers
a leatherman super tool (MUST have a knife!)
snap-on ratcheting screwdriver that stores bits in the handle.
2 allen wrenches ( Size to engine screws)
a spare key,
small extension magnet,
small flashlight,
Many, many, many, many zip ties.
2 spare spark plugs,
6 fuses,
a couple of spare bulbs, front and back
electrical tape.
a short roll of duct tape
a couple of clean rags
some bailing wire
a small volt meter.
3 tire irons,
a patch kit
CO2.
drive chain link and clip
I'm mounting a small side bag to the rear wheel, and without the voltmeter and duct tape, it should hold all this. What's missing?
