Knary had mentioned using the red canisters/cylindar fuel bottles. I've carried those around with white gas and plan on buying some bigger ones to carry a little emergency fuel. If you look on those canisters, you are only suppose to fill them to a particular level, this is to allow for the expansion of the gas inside. So if you use those, make sure not to top them off, and you should be OK, just check and replace the O-rings as Knary says. Carrying them on the outside of the bike is a good idea, just make sure they cannot leak onto anything hot like the exhaust.
