Does it clear up after starting and has the bike been sitting for a few days before it does this?

Thanks, ***** ***** wet sumping. Can you tell me the conditions of when it started doing this? (After an oil change, long ride, etc)

The bike is new to me 60 miles on it might have been sitting
Expert:  Steve replied 11 months ago.

verify the oil tank is not over filled. the oiling system REQUIRES a air space at the top of the tank.

new owners to HD tend to overfill the oil tank. the oil tank is designed to run around 2/3-3/4 full, but no higher.

you will need to disassemble the air cleaner and clean it completely to prevent the oil inside from dripping out.

let me know if you need more help.

correct oil level rode 20 miles no leaks until stop then gushed out breather tube
Expert:  Steve replied 11 months ago.

remove the allen screw on the bottom of the crankcase, left half.

collect the oil.

you should expect about a tea cup full, but prepare to catch up to about a quart.

tell me how much you got.

Does that drain the primary
Expert:  Steve replied 11 months ago.

it couldn't possibly be the primary.
