I tried to post this in the resourse center but it would not allow new posts.
Mods, please make this a Sticky.....
When you change out the exhaust, the SET-VALVE can cause your bike to get a FI Light and run in SAFE-MODE. There is a wire on the harness under the seat which has to be removed in order to trick the computer into keeping the bike running properly. This article is the HOW-TO with COMPLETE PICTURES from start to finish. It works perfectly!!!
Good Luck!!
Wiring
Remove the seat. You will need to remove the passage seat later so you can do it now if you want to.
Remove cross bracket. This is optional but makes it easier to work on.
Use a flathead to release both cable harnesses. Apply slight pressure and push towards the back of the bike. A second screwdriver can be used to help pry, don’t twist them though as you’ll score or break the connector retaining tabs.

Pull out both harnesses, the gray one is not needed but pulling it out makes the black harness easier to work with.
Locate pin 30, bottom row, 5th from the left. Yes 5th from the left. Black with brown stripe and green dots. Pin 29 (to the right of it) is also black with a brown stripe and green dots. Don’t touch it!
Cut the wire to pin 30. Cut it far enough up that you can reconnect it later if needed. Like for warranty claims.
Tape the ends with high quality electrical tape. Do not use el-cheapo tape as it will not hold for long. I always use 3M electrical tape. You can also use crimp on connectors made for ending a wire lead.
Reconnect both harnesses, be sure they are secure; things quit working if they come undone.
Freeing up the cables
Remove the right side fairing bolt and pop the fairing out of the middle rubber grommet
The goal, the SET cable
Loosen the bolts holding the cable ends in place.
Once loosened, disconnect them. It can be a real pain as there isn’t much play. In hindsight, it’s probably easier to disconnect the ends from the servo first so free up this end.
Prop up the tank. (Prop tool is in the “trunk” if you didn’t already know that)
Cut the cable tie holding the cables in place. Once you remove the cables, replace the cable tie with a new one. It’s there for a reason
You can pull the cables out now, or wait until you have removed the servo.

Control servo
Remove the passenger seat if you haven’t done so already.
Rather than removing the entire rear fairing, I choose to remove only the side that I needed to in order to get to the servo. Either way will work. I’ve never removed the entire rear fairing so I'm not sure how much easier, if any, it is to remove just the side.
Remove the 4 plastic fairing retainers.
To remove these, push the middle in, it should "pop" in about 1/4 of an inch.
Retainer pushed in
Retainer removed and still pushed in
Retainer “reset” and ready to re-assemble.
Remove the bolt inside the “trunk”.
The rear side fairing should come off pretty easy now; I just laid it over the top of the bike.
Remove the two bolts holding the servo motor on.
Disconnect the two wiring connectors.
Pull the cables out if you haven’t done so already.
Admire parts of your bike on the ground…
