question regarding oil warning - jan.van.gent - 31-08-16
Hi everyone,
I noticed today when pulling up (1/2nd gear from 4000 rpm to 8000 rpm), sometimes the oil warning light goes on (for a split second or little bit longer).
While the oil level is at max.
Any ideas what could cause this? Faulty sensor? Faulty oil pump? Or is this normal (oil goes to the back of the sump because acceleration?)? Bad filter (not enough flow)?
Filter and oil have been replaced by myself 2 months ago (3000 km's or so), standard 10W40 (motorcycle).
Best regards,
Jan

This is normal on some bikes. If the light only flickers briefly under hard acceleration it's nothing to worry about. The oil level sensors seem to be more sensitive on some bikes than others.

Oil lubricates your engine, the oil pump sprays the fluid to all corners of your engine. If the temp gets too high, or even worse, level is low or the oil pressure drops, the effectiveness of the lubrication is reduced. I'm not sure what causes it to be honest but I like your suggestion-(oil goes to the back of the sump because acceleration?) Personally I think it's best to have a little to much oil in the system than not enough. i.e. 2.8l is better than 2.6l

Put the bike on the centre stand, start the engine for 30-60 seconds, then watch the oil window until the oil settles.
That's your proper level.
Chances are there's just not enough oil in the sump.
The light is for the level, not pressure.

Agreed, I'd check the oil level. However the level is only an indication of volume within a closed system, more oil equals more pressure.

Yep I had the same thing and all it took was about an eggcup full
of oil to stop it.Re: question regarding oil warning - darrsi - 31-08-16

You and your egg cup.
An egg cup of oil spread over the area of a sump will do absolutely nothing!

Well that's the point, its a switch with an on and an off so there has to be a point where there is enough oil to not trip it and the difference between not adding any and only adding an eggcup full was the difference needed to not trip the switch, on fast acceleration.

The oil level is at max (at center stand).I rather wont add any more. I double checked this today. Its in deed when accelerating max, and mostly uphil.
So the sensor is oil level not pressure? Is there as well a pressure sensor (and warning light)? Because pressure tells much more than level. Especially during acceleration. Are there any baffles in the sump to make sure not all the oil goes straight to the back at acceleration? Or is the oil pickup at the back? While the sensor for the level is at the front?
My other bike is dry sump (wr250f) so never such issues there...

Just to confirm, this was checked after starting the engine for a minute?
No pressure sensor.

After drving for 1 hour and than rest it for 2 min.
Level is very close to max.

Make it an ostrich egg cup full :lol
Re: question regarding oil warning - darrsi - 31-08-16
You did state that it's mostly uphill when it happens.
As long as you know there's enough oil in there then don't worry about it.

I'd like to be the first person to use the term 'Viscosity' on this oil thread.
Re: question regarding oil warning - Shappaeye - 02-09-16
I always thought it was the 'change up' light.

Re: question regarding oil warning - fazersharp - 07-09-16
Come on - have you put that eggcup full of oil in yet
Re: question regarding oil warning - wickedmonkey - 07-09-16
Mine sometimes does the same accelerating hard uphill. Oil level at the max mark when on the centre stand on level ground.
Would like to know if your eggcup did the business.
