If you show only 50%, you are not following the instructions in the manual. You are supposed to ride for at least 9 miles, park on a level surface, idle for at least 20 seconds, stop engine and you have 10 seconds after engine stop to check the level. This is a dry sump system, there is no oil pan like in your car. If you don't follow the manual you will get a false reading because the oil quickly drains into the tank.
