I have a kawasaki ninja 250 r from 2005. I know that it is a water cooled engine and I cant figure out were to put it. I am not sure if what I found is the radiator. So i looked at the owners manual and found out that it is but everytime i look inside it is full of anti freeze or something. I tried once to pour water in it but it only took a little bit before it started to come out. Please help me in finding my problem.
