08 yz450. Finally got everything back together, put the oil and coolant in it and she fired up first kick. I let it idle about two minutes shut it down and when I pulled the dipstick the oil looked to be a milky white color. Now there is a small hole in my rad that is going to get fixed up tomorrow but that's external. From my research on this it could be water or a head gasket. The motor has been open but just covered up with rags while I wasn't working on it so could it be the condensation that got in it and mixed with the oil. It's been awfully humid and rainy lately or should I be leaning more toward the head gasket? Any input would be appreciated. Thanks!
