Where are the spark plugs located on a kawasaki ZX7 motorcycle?

first, take off the mirrors and upper fairing support (10mm), remove the front and rear seats, remove the four bolts holding down the fuel tank, (2X10mm) (2X8mm),remove the fuel tank, remove the airbox and filter, you will see the cylinder head exposed, you will see the 4 wires and plug caps going down into the cylinder head, these are where the 4 plugs are located, hope this helps
