I have a 2004 road king with 45,000 miles on it.I recently noticed oil leaking from around the stator plug.I also noticed that me engine oil level was getting lower.So,when I went to check my primary and removed the derby cover,oil poured out.That leads me to believe that engine oil is leaking into my primary case.My question is: is this a common occurence,what could cause it,and is it an easy (somewhat)fix? Thanks,Ben
