Some wire, channellock pliers, duct tape, spare plug, spare clutch cable, set of spare bulbs and, as addition to the tool kit,a socket wrench and the nuts necessary to adjust the chain (21mm/24mm? not sure). I have a small box with some replacement nuts, bolts and washers aswell. It´s nice to carry with you all nut sizes used at the bike so you can retighten all of them in case they´re getting loose. But with a channellock plier you´re on the safe side anyway.
Don´t forget to take some photos - and post ´em! Good trip & have fun
