Just noticed recently that when i go over about 100 mph using all the revs through the gears my oil light comes on and stays on untill i drop the revs and speed again.
There is enough in it, what else could this be?
Also why does the oil sight glass have the weird black u shape on it?
The Fazer oil light is a pain in the butt IMO. It reads oil level height and not oil pressure so it can be fooled. Maybe if you were doing 100mph on a slight incline, most of the oil might be sitting at the back or to the front of the engine and missing the oil sensor. I'd imagine if you were a Valentino Rossi type and was doing 100mph with the knee down, it might do the same again as most of the oil will be settled to the side. Scary shit though seeing a red light and don't know if its a false alarm or not and have to stop anyway just in case.
At least with an oil pressure type sensor, in nearly most cases when it comes on, you know there is somethng wrong and you need to shut that engine down immediately.
That half moon yokel in the window of the eyeglass is most annoying too. I find I have to get on my knees and look at the oil level close up than normal on bikes with a plain eyeglass. Maybe it has something to do with the sensor.
