+1 for fuses - if it is an intermittent problem the one spare on the bike will not get you to a safe haven. I know this from personal experience. Try changing the fuses in your GZ and you will soon see why I carry needle nose pliers.
I like the 1/4 socket set too. I don't carry a full set. Just the ones that I need. I also carry an adapter 1/4 to 3/8 to use the 1/4 inch ratchet with my 3/8 spark plug socket.
+1 for jumper cables. I got them and have needed them.
A roll of high quality electrical tape. I recommend 3M.
A flattened roll of duct tape. You can buy small rolls or use one that is almost used up. Get good stuff and put all of your tape in a plastic bag.
Cable ties and something you can cut them with. At least eight inches. These have got me home when a bolt broke.
I need to write a post about my tool kit. Something else to do.
