the oil light should turn on the off very quickly when you start the engine up, as i have the same bike, the nly problem i have with the bike, is when its on tick over wamrin up, it just dies, and ive tuned my carb etc to make it run alot better, but it just seems to die on tick over so i have to keep it at about 4000 revs for about 5mins till it will stay at tickover and not die on me.
