My 2 stroke is only good for about 40-45 miles on a tank. Thats with the throttle opened up a lot. I take an extra 5 gallons for a weekend and about 3 gallons a day (traveling) on longer trips usually no more than 15 gallons. I usually drop the spare jugs in a strategic location.<P>My wifes Sportsman (4 stroke) gets much better fuel economy.<P>6X6
