Sportster oil checks are done with the bike on the stand after a complete engine warm up to evenly distribute the 20-50 motoroil throughout. The dipstick will be completely inserted to collect the correct data. New sporties, when the dipstick is completely inserted, it will click and be flush with the oil tank.
The dipstick on a Harley-Davidson Sportster motorcycle is read by noting the position of the oil in relation to the markings. The oil should be between the full and add marks.

It may vary by model. My 1998 Sportster had a single oil system with a dry sump and an oil resevoir tank under the right side of the seat. The oil level was checked by a dipstick in the oil filler cap. I would run and stop engine, give it a couple minutes, then check it while standing bike straight up (not leaning on kickstand.)
