Jimbo, now that you feel like an even bigger dipstick . . .welcome to the club. I was going crazy at first with mine when I pulled the filler plug expecting to see a dipstick and there was nothing there, I was afraid to start the bike for fear it had broken off and might wreck the engine. I've also seen others with the same question.
So laugh, slap yourself in the head, check the oil and hit the road.
