Hello,
on a kz1000 ltd b2 78 i need to have right or left blinkers open to have the warning working.

Can you be more specific as to what the problem is ?
When you operate the switch for "left" what happens ?
When you operate the switch for "right" what happens?

Hello;
The flasher left or right works well.

The warnings don't work if i press the warning button alone.

I need to have the left or right flasher "on" and press the warning button to have the warning working.

 

Your bike should have two flasher relay units. One for left and right indicators and the other for hazard flashers (all four indicators flash).
If the hazard relay unit is missing the hazard lights will work if the indicator switch is turned left or right and the hazard switch is turned on. 
If the hazard switch is turned off the indicator switch will work as normal. 
You can use it as it is, hazard switch off and the indicators will work as normal. If you want hazard lights you will need to turn on the hazard switch AND either left or right indicator. 
If you fit the missing relay then the hazard switch will work independently of the indicator switch.
