hi guy. i have recently purchased a 1992 l2 zxr400 and when i took it out for a good old fasioned spanking i came back VERY hot :smt013 .
so obviously i checked the the water pump, fine so i checked the thermostat and although damaged and stuck it was stuck in the open position so shud still allow water through so i just took it out, buts it stil running hot and also the radiator keeps emptying itself into the coolent overflow bottle.
so what im asking is does anybody have a clue as to what it can be apart from the head gasket becuase i what to eliminate everything else first before taking the top end apart?

all help wud be greatly apreciated, thanks guys

could be airlocks in the cooling system?

with out sounding like a plank but how would i go about unblocking the cooling sytem?

also if it is the head gasket is there a way of checking it without taking the bike apart like a coolent system pressure test?

not really, only way is to take it apart.

a compession test may show up something but its not a definate guide.

take the rad cap pff and start the bike, squeeze the coolant pipes a bit to help the flow, it will need to get hot to open the thermostat so watch you don't scald yaself!

i have sorted the water/heating problem, it was the headgasket.
it only took like 6 man hours and was even easier when my dad did it without me even asking haha

cheers for you help guys
