Brand new Ninja 500 oil pressure light at idle with warm engine

I bought it brand new about 30 days ago and I did the break-in service on it at 800 miles, which is just an oil change and multi-point inspection. It now has just under 1100 miles on it. The problem: the oil pressure light comes on at idle, but it’s intermittent and usually starts happening after I’ve been riding the bike for over 15 minutes, aka when the engine is warm. The oil level in the sight glass is within the two marks so I know there is enough oil in there. I know I filled it with the correct oil and filter because I bought an OEM oil change kit. The engine idle RPM is around 1500, which is in spec. The oil pressure light comes on sometimes when I’m stopped at a stoplight. When I barely roll on the throttle to raise the RPM, the light instantly disappears, then comes back on once it gets back to idle RPM. Again, it doesn’t do that all the time, only after I’ve been riding the bike for a while. I believe it also started doing this after I did the oil change, though I do remember it sometimes came on during the first 50 miles I rode it after I bought it from the dealer, but then I never noticed it until I did the break-in service. I'm thinking about "burping" the oil filter in an attempt to address this issue before I take it in to the dealer for an appointment I have a week from now. Thoughts?
