Oil on fins

I have an o4 Road Glide with a stock motor. After a 30 minute ride, I am seeing oil on the fins of the rear cylinder starting at about the same level as the exhaust pipe. Any thoughts? Head gasket?

Also, any tricks to effectively cleaning the oil with out damaging the poloshed aluminum?

Get a flashlight and shine in there. That'll leave no doubt where the oil is coming from.

Thanks for the input all - took me a while see more oil after cleaning everything. After looking, i believe the oil is coming from the rocker box cover and blowing onto the fins.
