If you see a tube outboard of your spark plug you still have the AI on there. There is a kit available from several places to eliminate it. There is a pump under the tank. There is a large tube running to the air box, a vacuum line to the left intake (if I remember what side correctly) and a tube to each side of the head that injects air into the area after the exhaust valve. The removal kit consists of a plug for each opening left by the tubes by the spark plugs, a cap for the vacuum line, and a blanking plug for the air box tube.

I learned all I need to know about life by killing smart people and eating their brains.
