I have a 2001 YZF426, and before i put it away for the winter, I started up the bike,(hard time doing...very cold!), and put fuel stabilizer in it and let it idle/run for a while. The next thing I look and there is a puddle of antifreeze under the bike dripping from one of the hoses. When you revved the bike up, it came out faster too! What would be causing this? It was a very cold day, so is there a chance that maybe the water was frozen in the radiator??..any info would be nice!!
