Moderating power via secondary butterfly programming definitely goes on. I am the pied piper of removing the secondary butterflies and remapping the FI on the second Gen FZ1s. They were amazingly lazy to the throttle in stock form. Now it is an uncaged animal.
Yes those are the ones, very simple concept and
easier to manufacture, compaired to Yamaha's electronic vairible velocity stacks.

Removing the secoundary butterflies is a common modification, they do react very slowly coming straight from the manufacture. There are many other mod's you can do to make the throttle respond quicker, that is one method. FZ1's are no joke in the right hands.
