On the way home on Saturday I had done 80 miles (approx. 35 on the highway and 45 on the trails) when I hit reserve. This is on my old XR which usually goes to reserve at around 90 miles.
But high-rev's all day in 2nd & 3rd gear takes it's toll. I did NOT have extra fuel with me but someone riding with us did so I was able to push it to 126 miles. Ran out of gas just as I was pulling into the gas station and glided to the pumps. Now THAT is a good day of riding.
