I just bought the bike and the next thing I do is change oil and filter. Maybe it will help...

what kind of bike is it? is it when you start to release the clutch and put a load on the motor?

Still recovering,some days are better than others.

It's a 1984 ZN1100. And no its the opposite, its when I pull the clutch, not when I release it. Sorry if i expressed myself wrong, I'm french...
When I pull the clutch lever, the oil light turns on and stays on until I release the clutch lever.

I suggest opening up the headlight housing and see if a wire or two hasn't rubbed together. These are two seperate circuits and should not interact like this.
Vibration and the way wires are routed may attribute to this.If your bike is like the U.S. models, the clutch lever needs to be squeezed(pulled in) to start the engine.
It's another safety feature Kawasaki added to prevent starting the engine in gear.

Sorry guys, I was wrong in my symptoms analysis. The oil light turns on when the THROTTE is released, not when the clutch is engaged. These 2 actions often happen at the same time, thats why i thought it was linked to thew clutch.
When I give gas, the light turns off and when i stop the gas, it turns on.

These old bikes only operate with 2-3 pounds of oil pressure anyway,so it is important that the oil type and weight meet factory spec and there is the proper amount of oil in the bike.have u changed the oil and filter recently?Did u check the oil pump screen to be sure it was clean and not all clogged up?do u happen to have an oil cooler on the bike? Is it working properly?Have u taken the wire off the oil pressure sending unit and cleaned the connection.?Good luck.bj

This sounds opposite of most normal oil pressure switch issues as I've heard them. Usually it's when the bike is "launched" from a standing start that the oil pressure goes low. Why would the oil pressure switch complain when the oil rushes forwarded during deceleration?

Oil level is fine if not a bit high, but it wouldnt explain my problem. I rode the bike only twice 5 km since I own it... I didnt notice if it did that the first time.
I dont understand how that could possible: low oil pressure when idling? Euh....!?!?!

When throttle is released and oil light turns on, is either brake being applied?
What if bike speed is reduced from say 60mph to 20mph by cutting back on the throttle, but not closing the throttle, does oil light come on then as well?
Good Fortune!
