My son's XR100 seems to be overheating. We rode yeasterday and it was fine for a couple of hours, riding about an hour and taking a break each time. Then it just quit. He was practicing around an MX track. He pull under the tree in the center of the track and by the time I walked out there he had it running again. He road abourt 20 minutes and took a break. Later he went out and after about an hour of riding, some in the trails then back to the track it quit again. I pulled the plug, it was black with some small white spots. I let the bike cool, check the carb for dirt and put in a different plug. I worked fine again for an hour and a half or so and again quit. By then I was time to leave and I haven't looked at it since. Anyone else have this type problem or have any ideas.
