Oil tank leak?

I bought the O rings to fix the leak. They are still laying on my work bench in the shop. To lazy to change them out especially since it has stopped leaking. lol
 

Not sure if your problem is solved. I had the same issue on my new 2016 R3 Roadster. At the end the oil tank, O-rings, washer had to be replaced. I have many problems with the Rocket...
