Hi Guys I'm changing my oil on new 2016 350 EXC-F every two enduros (about 10 hours riding). Bike not hammered but gets pretty hot during these events. I short shift and do not need to rev hard. Consider myself smooth with gears. So surprised to see the magnetic drain plug has so much debris on it. Looks like this picture almost every oil change. The long bit looks like the tip of a gear but I might be wrong. Any thoughts here?
