One thing that can cause this is starting the bike, jumping and and taking off and riding fast and hard before the motor is up to temp. Luminum expands when heated, so basically when you are at operating temp, you should theoretically have your best seal. If the jugs are warped because of not waiting till it's warmed up, some have tried to hone them flat again with varied success. I always wait untill I can feel heat in the rear rocker box covers with my hand before I take off (usually not more than a couple minutes unless it's 20ş out)

I am reading this thread thinking that I am amazed that my HD's don't leak as a rule. When you consider the different joints and types of gaskets, seals, and torques. Between manufacturing tolerances and assembly. I think that considering how many bikes are made per year, HD did a good job. I have had two leaks on a 11 year old Evo with 30,000 miles. One leak was caused by a dumbass misaligning my belt and the other was failure of a paper gasket after ten years. My twin cam doesn't mark a spot or use oil after 50,000 miles and being worked on for up grades.
