Location of battery on a kawasaki zx-14?

The battery for the 2006 ZX-14 (I assume the same for all years) is not under the seat as it is on most bikes. It is actually on the right side of the bike just under the gas tank. You'll see a small 'hatch' where the tank meets the seat, remove that to access the battery. You do not have to remove the tank or the seat (I found out the hard way) batterys are normally under the seats
