Good list, I wrap elec tape around my socket extensions, takes up less room than a whole roll. Also cable ties are the the most used things for a bush fix for me(keep them in my bar pad), cable repair kit(for clutch/throttle/brake cable), spare gear lever is a must also(even the cheapest crappiest one you can buy), tyre levers, front tube(you can put a front tube in the back and it will work once inflated, not ideal but it will get you home), spare 2 stroke oil(if you ride a 2t obviously), spare plug and plug removal tool, about a metre of elec wire, and most importantly a roll of dunny paper in the back pack(nothing worse than wiping your ass with leaves!)
