Guys, just a refresher. I have a kawasaki zr 400 (xanthus). Created a thread a while back because of coolant queries. So upon further use of the bike, after about 2 weeks of commute, I inspected the coolant in the rad, have found that theres no water and coolant left in it, though it never overheated and the temp gauge is always on its half scale. Question is, is it normal for the water in the rad to disappear in the 2 weeks of ride? Where do you think the water goes? I dont seem to see any puddle of water on the garage floor. What could be the possiblem problems in my cooling system. TIA guys.
