Ride it. Seriously.
That's just some mist from the transmission vent.
I would check the level of the transmission oil. It may be over-full.
Then, I would ride.
No, I wouldn't waste my valuable time screwing with a dealer over something like this on MY bike.
No, I would not take my bike to a dealer who tells me there is a one-week wait time to look at something this simple.
Ride it.
