Oil light stays on

Not sure if this portends more problems down the road. This is on the KZP with 44K miles. It has a few oil leaks but is not low on oil and runs strong.

It likely means the oil pressure is low for whatever reason. Best to get a gauge and read actual pressure. As somebody pointed out, you can juice the pressure up by switching from 10-40 to 20-50 but that's not addressing the problem. Could also throw in a can of STP high mileage and get the same effect. I kind of doubt it's the pump but it could just be wear on the bottom end. My 750 twin has 84k miles and the light stays on for a few seconds after a cold start but it does not come on at idle.

I was riding across the US and stopped to have the oil changed while on the road. That is when I found that lighter oils would cause the light to stay on. I have about 60,000 miles on the bike now with the only problem I have had was valve seals needed to be replaced.
I live in Oregon now and only rarely ride but usually when it is warm.
