limiter caps

Hello

i rebuild a kz1000 ltd b1 carb and i would like to know how to set the limiter caps.
I know how set the carbs without (seat then 1.1/4 turn off)  but not with them...

How to use them?
 

Take them off or leave them off… 

I vote for tossing them in the trash bin. They were designed for the U.S. market to prevent owners and mechanics from adjusting them in a way that would increase exhaust emissions. They were set on the lean side by he factory to keep the government happy. Unless your state has some law requiring them to be in place, you can pry them off and set the mixture where the engine runs best.
