Its normal. :thumbsup:

The main reason why is that that's the crankcase, and oil belongs there. The probable reason there was so much of it is that you hadn't run the engine in a while (your bike is most likely an '05 or earlier steel framed model, too).

Unlike two strokes, the actual central part of the crankcase is not a part of the intake tract, and needs no main bearing seals when it shares oil with the trans as the YZF does, and wouldn't need a seal on the ignition side anyway.

As to why there would be more oil after it stands for a time, read:
