try and see where it is coming from.these bikes suffer with the main water hose cracking and leaking so check that its the one that comes fromthe water tank under the tank lid.

some running it before it completely nacker it. sounds like a lscrew come lose on a hose, or the termostat might be gone. more than likely the radiator tho. thats expensive. not sure but think you can get stuff for leaks tests, specifically water systems. google
