Hey Jonesy, the only way to see how far, drain the tank using the 'On' position. Then add exactly 1 gallon. Have someone follow with extra gas. Punch the odometer, head out and run'er dry! Then flip the petcock to Reserve. Then, notice the miles and keep on going till it starts cutting out. Your friend has gas fore bike and you now exactly how far per gallon. . . And, ya know how far the Reserve will take ya.
Cool, huh? Its not mine, somebody told me. Enjoy! It's like a science experiment!
