engine oil pressure light coming on, and then off

[mike.sg]

Hey everyone,


My first post!


So I just bought my bike, an old Gen I. Everything seemed to be working well, until recently when the oil pressure light starting coming on.


I went back to the shop, and they added about 300ml of oil, and the light went away.


Soon enough though, the oil level dropped from above the max level on the sight window, to its current position between the max and min levels, and had stayed that way since.


However, yesterday, the light started coming on again. It turns on even when I'm just riding along on flat stretches, and will often just turn itself off after a while (within 3 minutes).


So, I suspect I am dealing with a faulty sensor? Is this something to worry about if the oil does never drops below the min level in the sight window?


How should I go about finding out the cause of this warning light turning on?


Thanks guys!


regards,
michael
