Engine light after exhaust install. Servo issue

My engine light came on after installing my new exhaust. Turns out to be an issue with the servo.
Remember, the servo disk was removed with the cables and replaced with 2 parts. One on the bottom with the "V" was mounted via the philips screws and the other mounted on the post and would swivel.
To fix the issue, I removed the seat and the "new" rotating part for the servo that came with the muffler. I turned the ignition on and watched the servo "post" rotate a couple of times to see what center was. Working the key on and off a few times to get the "post" to the center position. Set the rotating part back on the post and rotated it until the arm contacted the "V" one way, made a reference mark pointing to the center of the "V". Then did the same thing in the other direction. Then made a larger mark in the center of these two and aligned it with the center of the "V" and tightened it down. Started the bike and the engine light was out. I was prepared to have to rotate it slightly, one way or the other but wasn't necessary. Beats buying a servo buddy for $50.
