same problem as mine (someone posted link above) with my deluxe. dealer replaced gaskets and o-rings.. both my jugs were weeping. after replacing it seemed to solve the issue. then a leak occured inside the case pry hole. so they sealed that up with case sealer. so we shall see.
My 2013 Heritage is doing the exact same thing. Blows tiny bubbles when cooling down. Front jug is the worst. 1350 miles.
UPDATE: At about 2K miles mine quit doing this. I cleaned the residue of with gas on a rag and no more "leaking". In my case at least, it was a casting residue that eventually "burned off".
they cracked open the case on mine.. after 2 visits and sealer, etc... and said it was not sealed properly so they re-sealed it. so the pry hole leaking and oil bubbling stopped and seems fine. still see some light weeping at the rear cylinder. but very, very light at this point.
