So I went out ridding for the first real time this year, about 5+ hrs of hard ridding. When I was loading back up after, i noticed that I have a small hole that is open on the kick starter side of the motor, on the head. I know it was never *open* before, it is on the side bottom of the head, and i think it is one of those wholes that are plugged with a small steal ball, but I have no idea why it is gone. Any and all help would be great. The bike still runs fine and there is just a small amout of oil that leaked out. Looking inside it almost looks like a valve is visable. Thanks guys!!
