It is unlikely that it is a head gasket that is leaking. You should do a compression test just to check the head gasket. If the compression is around 120 on the rear cylinder then you may have a head gasket leak.
If it is oil that you are seeing then it could be coming from one of these locations, the "O" rings in the pushrod tubes (the top o-rings in the cylinder heads are the place to start looking) the rocker box cover and rocker box gaskets are what you should look at next.

Rocker cover gasket is a easy DIY. Just pull the fuel tank which takes about 10 minutes and the remove the 6 bolts holding the rocker cover on, then put on the new gasket and put the 6 bolts back in the rocker cover. You don't need a torque wrench for this job you just need to snug up the bolts pretty good, DO NOT OVER TIGHTEN the rocker cover bolts the rocker box is aluminum and it is easy to strip the threads in the rocker box.
This is a 1 hour job tops.
If the rocker box gasket is leaking it will take a little bit longer to do the work, 2 hours would be about right.

Thanks for the info. I will look into it this week.

The rocker cover gasket is only around $10 and the rocker box gasket is only around $10 too.
If the rocker box gasket is where the leak is it isn't that difficult changing that out either.

always use a torque wrench to help eliminate leakage. any other way is just guessing. dsv
The trouble is that you can't get the torque wrench on all the rocker cover bolts. The rocker cover bolts and the rocker box bolts just need to be snugged down good.
There isn't any reason to take the bike into the dealer for a top end oil leak unless the bike is still under warranty. The pushrod tube o-rings and the rocker box and rocker cover gaskets are a easy DIY.
