FYI, you don't need to actively bleed a cooling system, most systems (and i'm assuming the ZX14 is simillar) have the radiator as the high point in the system which will force the majority of the air to the cap, when the engine heats up the air is forced into the overflow resivor. When the engine cools the excess coolant (minus the air) is sucked back into the radiator.

Now would be a great spot to start chatting about vapour lock in the cooling system and the possible impact it could have on the operation of the thermostat, hot spots on the engine block, etc... but i'm lazy so i won't get into it, just make sure you try and get rid of as much air as you can before putting the cap on the rad and going out for a ride.

i CHEAT BY DRILLING A 1/8 HOLE IN THE THERMOSTAT IF IT DOES NOT ALREADY HAVE ONE. SOLVES THE PROBLEM OF GETTING TRAPPED FROM THE HOSE THAT GOES FROM WATER PUMP TO THERMOSTAT.
ON MY ZRX'S YOU HAVE TO BLEED AT THE WATER PUMP AND THERE IS A BLEEDER VALVE IN THE T-HOUSING. IF YOU DO NOT DO BOTH IT MAKES A NICE LITTLE AIR POCKET WHICH IS WHY I DRILL A HOLE.
