FZS 600 Oil level light

[NJD]

Hi,

Did an oil change about a month or two ago (at most) and all has been well since then. Last couple of commutes home (at night) I've noticed the oil warning light come on.

First time I pulled over right away, off and on with the ignition and started it and it went out and stayed out.

Second time, the day after, it came on and so I pulled over. Off and on with ignition and it lasted a moment but went out again and stayed out.

Drained some oil today as the window was clear brown (mistook the inside of the engine for oil, couldn't actually see any) and the light came and stayed on so I turned the engine off and added 1.3L approx (over 1L but not sure by how much). Ran the bike and the light is now not on at all. I tilted the bike due to the angle of my path not being level and there's plenty inside with the oil at the top, I just hope I haven't overfilled.

When I did the oil change I added what I thoguht was 2.5L (or a little over 2L) using the marks on the oil bottle but there's no signs of leaks, and there's no oil stains on where I park (at home, or work) after a ride; or any signs of leaks. I didn't measure the level at the time based on an uneven path, but also because 2L (or just over) should be enough regardless since capacity is 2.5-2.7L overall.

My question is:

a) will the light come on if the engine is overfilled (its hard to tell as my path is a slight downwards slope, and not level) or does it only come on when the engine oil is low?

b) how do i tell if the oil level switch/sensor is faulty, is there a way to test it?

c) is there any common places for it to leak I wont notice as it would fall onto the road/burn on ehxhaust during ride? Engine case seals, front feed pipe

I don't actually know if it was low, or if it was a faulty switch; by the same token I know don't know if i've overfilled. The only sign it was actually low is that the warning light came on after I drained some out, but lets just say the sensor is NOT faulty and it the oil was low then where the hell did my oil go?

Well known and common fault on the 600, try cleaning up the electrical connections to the switch.  It's a level switch not pressure switch.  Providing there's the correct level in the oil window, there's nothing to worry about, it's just annoying.

Sounds like you underfilled it. Like Gnasher said, it's level not pressure, so don't panic too much. If my oil has ever been low it comes on under acceleration. If you put 2 litres in and now put another 1.3 that's too much by the sounds of it.

Like Gnasher said I think its probably just faulty based on water/cold weather perhaps causing issues with it, but again my confusion surrounding being able to see my oil level due to a downwardly slanted path being my own place to check the oil level only added to the drama (first time i've done it where i currently store bike as previous location was perfectly flat, or more ideal it seems).

I did drain some oil out before adding the 1L-1.3L in an attempt to lower the oil level in the window (which later turned out to be the inside of the glass due to angle of the bike, oops -- which is why I added the 1L-1.3L after).

I know now to ignore the light, and may drain a small amount of oil out. I think I'll be okay, despite oil being at top of glass, due to draining some out before filling again but also that I'd left some leeway when I did the oil change too.

I pray the front oil feed pipe doesn't give up the ghost during winter, here's to more fun on the cards.

Thank-you both.
