Just got 06 YZ450F, first 4 stroke that I have owned so as you can imagine I have a lot of questions and a lot to learn about this bike. Here is the first one bike has about 3 hrs on it. When bike was idling and warmed up noticed coolant coming from the weep hole on the water pump cover. not sure if this is normal when bike is idling for extended time. But suspect water pump seal leaking. Our my suspicions correct?
