As I thought about this problem. I considered a few things.

#1. There are only 4000 miles on this bike, so the starter can't be that messed up.

#2. When I first started the bike it didn't make this sound

#3. The only thing that changed since it first started was that fuel made it's way to the crankcase.

#4. The starter clutch is sitting up high, so contaminated oil won't be lubricating very well up there.

So I changed the oil out with some Castrol 10w30 and sure enough. After the bike ran for about a minute, that terrible whirring sound went away!

As much as I don't like to shop at wal-mart I must say that their 24hr. shopping and wide variety of cheap oil made me very happy that night!

This means I'll have to change out that petcock and not just rebuild the vacuum one.
