Default suddenly dropping oil

Trying to guess why my 2019 Sportster is suddenly dropping oil. I took it out for a first ride of the year, ran fine, but when I came out the next morning, small pool of oil under the bike. I can't figure where its coming from, I only feel oil on bottom of a tube running under motor. Ideas?

Did you fill up the oil tank before your ride? If so it might now be overfilled if a lot of oil from the tank had slowly made its way into the sump and then got pumped back to the tank when you rode the bike...that could explain the leakage.

Maybe post a pic of the area of concern. Maybe your buddies are playing with you?

Start by checking the hose from the oil tank to the oil pump on the underside (right). You'll need to lay on the floor and look behind the exhaust up against the motor. The hose clamp on the intake side starts to leak.. Then check the drain hose from the oil tank. They leak after the rubber dries up. The air breather blow-by fittings are fed into the intake and if the BB builds up it'll leak onto your right leg. Those are the most common ones.

Do you let your bike warm up a little before you ride it? I dont know about the newer ones, but the older Evos sure liked to weep some oil at the rocker boxes and base gaskets if you run them before they get warm.

This happened to me once, worth a check.
