It is normal for Harley Davidson motorcycles to push oil from the crank case breathers into the air intake/filter. Google Harley breather by-pass. The EPA mandates that carry over be routed to the intake stream. I'll save you a trip to the dealer:
It is normal,but usaually not seen for many thousand miles.Every 5000 miles Your air cleaner needs to be cleaned and You will notice some oil in the cleaner and its housing, If You have low miles and notice oil, then the air cleaner tubes that vent the crankcase may be misoriented.They need to point into the throttle body.

Not necessarily. I did my airbox mod at around 1000 miles and there was oil in the throttle body, about half a teaspoon full. Bike doesn't use any oil, and I'm now at 7000 miles. As someone said above, "They all do that."
My 2003 Honda VTX didn't let the airbox oil accumulation drip out of the airbox. They put a small clear plastic tube onto the bottom of the airbox. Oil would drain into the tube. Owner needed to remove the tube now and again to drain the oil out.
The inline fours do it also. Owners tend to fret about it, and most of the forums are littered with threads about it.
That was true of my two Harleys, the 2016 and now the 2018. Both about 1/3 or so qt overfull on Day One.
In fact, pretty much every new ANYTHING I've bought has come slightly overfilled. Best guess is, it doesn't hurt anything, and they expect new engine to use some oil during break-in. In my case with the 2018, I used a baster to remove the excess oil and get the level down to two dots below the filled mark. I then rode the bike break-in style another couple hundred miles, checked the oil, and it was near the bottom mark. Had to add oil. I probably should have left it alone.
And oddly, my tranny on the 2018 was right at the bottom mark from the factory. I added about 4 oz to get it to the top.
Dale I fashioned a catch can really easily and for 6,000 miles its been working great. I check it about every 1,000 miles and there may be less than an shot glass full of mostly water and some slight oil residue. Took all of maybe an hour to do.
