For the first time I got my "new" XR650R running. SWEEET. Now along with my oil question (see oil level post), I need to figure out the trip meter. I figured if pull the knob out to the left I can scroll backwards, all the way to zero. Man that seems lke a stupid way to reset the trip meter. Please tell me there's an easier way! And should I lock tite the knob to make sure it doesn't fall out as well?
