Does it read low after sitting for a long period?
Mike   no it doesnt,i dont see any leaks anywhere.it dont smoke or anything.thanks for your time. tony

Answer
There is only three places that the oil can go. On the ground, sits in the bottom of the motor or in the inner primary. SInce you dont have any leaks, thats out. If it were sitting int he bottom of the motor it would blow out when you started the bike. You could have a leaking main seal in the primary, which would dump oil into the primary. Remove the inspection cover and check in there when the oil is low on the stick.
Good luck and happy riding
Mike
