Hi Ted,
We've all been there...
Your kit list is a good start assuming you've included the minimums for a tire change (jack, tire iron, etc.). Some additional items to consider:
Flashlight (w/ magnet or a snake light)
Fuses
Electrical tape
Tire pressure gage
Some spare bulbs
Jumper cables (if you're running 12V)
If you have extra room you could include a small hammer, a file, a socket to fit the spark plugs, and a small wire brush.
Good luck and have fun.
Bill
