Oil light coming on and staying on just after star

I just changed the oil in my kz1000 and the oil light is coming on shortly after it starts.
It flickers but more on than off. what happened, I took the oil filter out and cleaned it with gas checked all the "O" rings and put a little oil on the rim and put it back together.

Hello, noroaches, and WELCOME to KZr!

Perhaps the gasoline soaked filter is partly responsible.
However, there's a filter by-pass system that's supposed to allow oil circulation around a clogged filter.
Imo, it's best to fit a brand new filter, rather than attempt to clean a used filter.

Couple of other possibilities regarding the oil pressure warning light:
Defective sending unit;
Faulty wiring or loose connection;
Clogged oil pump screen;
Poor oil pump performance resulting from other than clogged screen.

Could fit an oil pressure gauge to determine actual performance.

The oil sending unit is relatively easy to remove and replace.

Good Fortune!

If a new "oil pressure switch" (aka oil sending unit) is needed:

Good Fortune!

If the oil light/switch was not a problem before the oil change then it should not be a problem now. More than likely the oil filter I have to ask why would you even try cleaning a paper filter in gas

ok I will get a new filter. where is this screen that maybe plugged, can I clean or replace that

there was only a steel filter, no paper filer at all

Oil in the sump passes through a screen into the oil pump.

Access to the screen and pump is by removing the oil pan on the bottom of the engine.

Good Fortune!

Here's a link to the Z1 FSM (Factory Service Manual) in KZr's FILEBASE:

Check out the oil pump diagrams and information.

Good Fortune!

Perhaps there was no filter, and just the bolt (with holes in it) that attaches the filter cover.

Am unfamiliar with any type of steel filter being used instead of the usual stock-type paper filter.
Perhaps seeing the gutted skeletal remains of a paper filter. :ohmy:

Good Fortune!

What weight oil did you use?

It would help a lot if you were to add your bike's exact year and model to your signature line. Not all KZ1000 bikes are exactly the same. Ed
