Where is the spark plug on a kawasaki ninja?

I'm guessing the same as most other bikes... under the gas tank. take a look at this video YouTube.com/watch?v=Ct31s5JNhyM">http://www.YouTube.com/watch?v=Ct31s5JNhyM

The spark plugs are located under the gas tank and under the air box. You need to remove the top and bottom of the air box and you will see the plug wires. Be sure to reconnect the ram air lines properly or your bike won't run properly above 50 MPH.
