I have a 94 Zx11. I was comteplating playing with my jets. The little C-clips on the jets, what is their purpose. I am sorry to ask, I can rebuild and tune automotive carbs. When I took my KEI carbs apart I was LOST! I I pulled the just out and move them up or down one notch, what effect would I get? Is it better to get a new set of jets and play with thoose?
