Clean it up and put it back together. Now that you have a 1000 miles on it , ride it hard your next few times out. not red line hard but take it up to 5-6k RPM before shifting gears and re check after a few hundred miles. You will see the motor start to burn and consume more oil. All bikes and riding conditions are different, climate etc... Half dollar is a bit much but its a new bike and if you babied it your first 1000 some recirculation is normal. Again, I am not a harley tech, just a guy who has owned several and been riding for 30 years. But I would Definately keep a close eye on it and double check your oil level when bike is hot on Kick Stand and screw dipstick all the way tight before you check. It will tell you on the dipstick where the level should be when hot on stand. I only say this because your bike is brand new and shouldn't have any compression,piston or ring issues that may otherwise cause this amount of oil in your breather.
