Bill - I got 4 bikes and keep basically the same on every one.
cable ties, wire, misc. nuts and bolts, tape, small flashlight, small volt meter, probe light (home made with just a 12v bulb and soldered leads), stubby racket, sockets, open wrenches, allens, small needle nose vise grips (a must), screwdriver with interchangable tips, needle nose long pliers, lenght of surgical tubing (forgas), length of gas line (to gravity feed if the pump goes), hose clamps, extra bulbs for lights, wires made up with alligator clips on each end incase I lose my keys to hot wire or bypass wiring, fuses, fan belt (on the Boss), can of motorcycle flat fix, rubber gloves, cut down flares, bungees, bungees, bungees
what I am going to add to the Boss kit: cheap spare electric fuel pump (smallest available) , battery jumpers a set made up if I ever had to buy a battery strap it to my seat behind me and just jumper it to get me home.
At swap meets, I am always looking for items and tools to add just incase. I have bailed out many a broken down biker along side the road.
The one time my fuel pump went on the boss I was lucky and just beat the crap out of it every 5 miles or so to get it going enough to get me home.
