Estimated Time: 20-30 minutes if you're really slow
Applies to:
All FZ6 Years produced for the USA
What you need:
Yamaha's tool kit that came with the bike or appropriate tools.
Some thin wire ( I used 18awg solid core but it doesn't really matter)
I also used two pairs of pliers to pull the connector in question apart.
Why I made this:
As you may or may not know, there is a Co adjustment built into the FZ6 and other Yamaha's that supposedly allows you to richen or lean out the air fuel mix. Since I have Scorpion exhausts and they tend to lean the bike out / you can get more power if you do the Co adjustments... I've made this for the community.
Special Thanks:
I would like to thank krid80 for his information on the subject. I decided to make this because it was way to hard to search and find the information on this.

Instructions:
- Remove Tank
a. Remove the hinge bolt with the included bike ratchet
b. Remove the 2 allen screws with a 5 mm allen wrench
c. prop the tank up on the handlebars or however you feel comfortable - Locate Harness
It will be near the frame in the red box note that it's directly under the tank.
Lets take a closer look...
Notice the connectors. You're looking for the semi clear 6 pin connector. In this picture it's the one in the back behind the white connector.
Here's the connector you want all by itself. - Pry the connector apart. It will be tough but it'll come apart. I used a pair of pliers and a flat head screw driver to loosen the connector
- ground the wire - You will be grounding the wire that isn't connected to anything. It will be yellow with a red stripe and brown splotches
- Test the results! - Now it's time to do the adjustments
