i have a kawasaki ninja 2007 250ex and it began heating the other day. it idles twice as high as it should be and it began to leak coolant onto my garage floor, removed left fairing but not sure what to do next, any suggestions on what it could be? what i am looking for? or what to do about it? not terribly handy but i would like to try, please help! thank you.

 

Welcome to KF

Is the coolant coming from the overflow tube?
