Bought a used 2017 Desert Sled a few months ago. Has just under 6k miles on it and since I have no idea about the history of it, I figured I'd do the oil change 1,500 miles early. Bought the insanely expensive Duc oil... and a new K&N filter. All went as expected. Drained oil, blew out screen, swapped filter and started to fill up. I got 3 of the 3.7L in and she was real full. Started it and let it idle for a couple of minutes and checked the glass. Had to drain about half a cup. I guess the oil cooler will hold some oil but that much? Seemed a little odd. Oil was warm when I drained it and I was very patient. Even tipped bike from side to side to make sure I let it all out. Is this common? You guys getting similar results?
