Just change the oil and see how it goes.
Its hard to tell how much water is in the oil without doing a test.
If it happens again it may be a waterpump seal.
These were a minor prob on the 98 YZ/WR.
If the bike is using water then its prob the seal.
Replace it with a 99 seal and possibly a 99 shaft. they have different coatings on the shaft.
