These are fixed under the fuel bowls, keeping everything in place and preventing bowl distortion and leaking.
There are some new CNC machined billet fuel bowls, and machined plates, but I like to do things myself. (And often fuck up everything in the process).
You can check out some fuel feeds I made on the lathe also.
The FZX frame is a bitch, with those two upper frame rails right in the way of the carbs, so you have to get around things sometimes to make everything work right (without resorting to heavy power tools or big hammers...)
Enjoy.
Comments always welcome...
