I am new to this forum and I hope it is OK to ask a mechanical question. I have a 1999 Yamaha fzs 1000 At consistent speeds of about 50 MPH or more, after several minutes, my oil light turns on. If I pull in the clutch and let the RPMs go down, then the light goes off after 10 or 15 seconds. If the bike is setting still and at idle, the oil light does not turn on. I am sure that there is plenty of fresh oil in the bike and at the proper level. Has anyone had this same experience? Is this something that I should be concerned about? Does this sound like a bad sensor and is this sensor easy to replace? I would have thought that if I actually had a low oil pressure problem that the sensor would go on at idle and possibly turn off when the engine is at higher RPMs but I am seeing the opposite. Any opinions would be appreciated.
Hi as recently posted its an oil level switch not a pressure switch.If u keep the oil topped up to the top of the sight glass it will be ok.I.E just leave a small air bubble in top of glass whin u fill
The oil light is actually a level sensor and not a pressure sensor. That being the case since the light only comes on at elevated and sustained engine speeds it sounds like your level is to low, or you are having a drain back issue.

I had a similar problem on my XVS 1100 (year 2000). Light keeps burning even after topping up oil (which was not necessary).
Turns out it was a defective print receiving the signal from the oil level. Shop says problem is known, but the new print should work for a couple of years.
