You should buy probably buy 5w40 this is the most commonly used oil for motorcycles but realisticly the 250 is not picky and anything will work. the one thing to make sure you dont buy energy conserving oil, I guess its not good for the clutch. http://faq.ninja250.org/wiki/Engine_Oil
Check the oil cap and the drain plug, as well as the oil filter.

10w40 but it should be approved for wet clutches.
its not really picky but I'd go for 5w40
it says 1.9 liters on the side, that's about 2 quarts.

Im assuming for the oil? if so it is on the underside of the bike right under the clutch. It just looks like a bolt, the round thing right next to it is the oil filter.
