Hes got the Akra map. That prevents the CEL from being displayed when removing the valve. At least, it did on my bike.If you unplug and remove the diaphragm valve, or what ever that think in picture two is, you will get an error code and a warning light on the dash.
I cleaned tubing plugged TB and remove the can and valve...taped the plug for idiot light and zip tied it out of the way!
