I just recently noticed I have some oil that must be collecting in the air cleaner cover and ultimately drips straight down then blows all over the place in the wind. It's not pouring out but noticeable. 13 street glide. What could cause this. Thanks

 

Your crankcase vent tubes direct crankcase gasses into your air cleaner. When it drips, its usually time to clean your air filter and cover.

 

I keep my oil under full by 1/2 qt. overfilling can cause that.
Also if someone used a recharge kit on your air filter they could have soaked the crap out of it causing it to drip as well.

 

Your engine breathers are routed thru your heads and in the back of your air cleaner.

 

 

Oil was changed and new filter 2000 miles ago. It is a reusable filter

 

Yep, that's about right.

 

Then check the two things I mentioned.
1) see that the dealer did not overfill you.
2) see that the dealer didn't bang you for an air filter recharge kit and spray the crap out of your air filer with recharge oil.

 

Was a brand new filter installed. I watched him. Indy shop
