Here's one I've done. Create a container of coffee, sugar and dried milk. It is all ready-in-one.
Don't bring 2 mess tins, one is enough.
A bar of sunlight soap is good for washing clothes or better still just wash your clothes with you in shower with shower gel.
If in doubt, don't bring it, remember you can buy most things you actually need on the road.
If you are travelling in eastern Europe, don't bother with a stove: food and drinks are so cheap, it is unnecessary.
Bring an iPhone/Smartphone, rather than a laptop with you if you want to keep in touch via WiFi. (But make sure data roaming is switched off)
Use a jumper for a pillow.
Get a one man tent that opens from the side.
Bring raingear.
Bring a light lock, you will be with your bike most of the time anyway on tour: u locks are very heavy.
Couchsurf effectively and leave your tent at home. (easier said than done, I like the security of a tent backup)
