By any chance have you changed your own oil on this bike?
I ask because people in the past have missed the oil checking portion of their owners manual and overfilled their oil. If you use an entire Victory oil change kit you will overfill your oil. If you don't check your oil correctly and add oil or check level during oil change you will over fill your oil.
If your high level is too high oil the excess may blow out.
