Recently I became the owner of the motorcycle Suzuki Savage LS 650 from 1987. I wanted to ask how do I know when the oil pump was canceled in my drive? Namely, there is no red indicator (oil lamp) on the instrument panel. Is there any other type of indicator that will show me that the pump does not work?

The oil pressure varies from 5 psi to 50 psi.
I think they didn't include one cause it would scare people.
