My boys are riding a junior enduro this weekend. Its one 18 mile section. I'm concerned about the nine year old on an 02 KX65 making it on one tank of fuel. He's done 15 mile sections OK but I've never checked to see if he can go 18 miles. Has anyone done any fuel milage testing to see how far the KX65 can go on one tank? He's an aggressive rider and keeps it in the power band. There may be a road crossing where I could refuel him, but he is not going to want to stop if there is a chance he can make it.
