I used spun aluminum bottles to carry white gas on long back packing trips. They are very robust and you get a good feedback when you screw the cap on with the plastic O ring. They will not leak, so you dont have to worry about gas getting on your clothes.
Two liters will get you 30 miles on a stock 650 (with no windshield / speedbrake). Thats good insurance when you are riding in unknown areas and cannot be sure where the next gas station will be.
BTW, if you have to use the gas in the bottles go backwards to the last gas station you passed (if its within your range) - dont hope there is one up ahead unless you are SURE!
