Today i started the engine and the oil warninglight wouldn't go out. The engine was running for about 30 seconds.
The engine is a 1999 fireblade and there is more than enough oil in it.
Could there be something wrong with the wiring or could be the oilpump ?
Please some advice

Thanks, Marco

disconnect the wire from oil pressure switch if the lamp is still on you have a wiring fault if it goes off then you either have a faulty oil sender or an oil pump/pressure fault
hope this helps

I would try that as it could be a genuine oil pump failure. The best thing to do is swap the switch or try a capillary oil pressure gauge.
Turn the engine over, but make sure you disable the ignition. If your pump has failed and it starts, goodbye engine

if it was mine, i would remove the plugs to ensure it doesnt start and to save wear on the starter, dribble oil down the bores to ensure they dont scrape too bad, and then have a friend turn it over on the starter whilst i looked through the oil sight glass to see if oil is getting sucked up when it turns over. A better way might be to remove the oil filter and crank it, to see if oil squirts out anywhere, but this would be a little messy.

A few months ago i let the engine running for about half an hour with no problems.
At that moment the oilpressure warninglight was not connected.
Would the engine survive that long without a good oilpressure ?

In a word, NO !

A car might, but not a bike engine, they're just too fragile.

Then it must be something with the wiring.
Thanks, Marco

Problem is solved, thanks guys.

The wire for the oilpressure was broken.

Thanks, Marco

Phew!!!!!!!!!!
Bet that is a relief !!!!!!

That's why I like a pressure gauge, when the lites on its over.

I know if the engines up the spout its up the spout but twice, once a lost sump plug and one a blown dry sump hose (dry sumps can fail too) the early warning from a programmed gauge save the day, that's why the 1st engine in the GT12 was called the cat. It used up plenty of life's.
