Check tank vent or petcock.
Do you run a filter?
Try these for a start.

cleaner and used Brasso. The only thing I haven't done is
put on the tubes into the breather box.

Oh, and run a can of seafoam through your tank. I get lucky a lot of times with this stuff when my carbs are being tempermental. Nice fix for under 10 bucks.

Is your gas cap clean?
It is your vent.
How about the petcock?
Had a to small of a fuel filter on my first KZ1000.
It would run the bowls dry after sustained high rpm.
Also run a barrel valve (hardware store) instead of a petcock.Requires some welding and fabrication.

rebuilt, cleaned and set the floats to 21mm per factory manual.
I have taken apart the petcock and cleaned it out.
I don't know what else to do, except take it to a shop.

I have put in a set rebuild kits, cleaned everything with carb
cleaner and used Brasso. The only thing I haven't done is
put on the tubes into the breather box.
So your running cv carbs without the velocity stacks??? If that is the case, get the boots on and the box sealed up properly and your problem should go away.

I will check fuel level in bowels next....
Great idea. And should perform clear tube test to determine actual fuel level inside float bowls.
The fuel level is far more critical than float height.
Setting float height to specs may get in the ball park, but often fails to result in correct fuel level.
Good Fortune!

Yep. For me setting them dry was a complete waste of time.reaver573 wrote:
