Seriously check this link, it has the oil changing procedure for all years of these bikes. It's one of the first things you'll come across when you scroll down.:smirk:

Because whoever you bought it from probably over filled it.

Because it was overfilled.

There's also a link to a free manual download in Common Threads.
