Stock tool kit with a few additions.
2 spare spark plugs
1 spare headlight bulb
small Mag light
tire pressure gauge
As I ride and RT, I also stuff a spare front and rear tube in the pockets of the fairing.
Never needing anything more while touring. I tend to be very minimalistic. Take what I know I can use on the side of the road to get me somewhere to do permanent repairs.
Others will tell you to take everything in your garage, and your two neighbors garages as well.
Oh, and I NEVER use vicegrips on an airhead.
Most of the stuff you list is actually in the stock tool kit, or at least should have been there when new.
