Light brown oil after winter

I have an 03 hayabusa. Started it up a couple times during the colder months( I live in ny) went to do new coolent and new oil to have it sit for the rest of the winter and the oil is a light brown color. I've been reading a couple forums I've seen it can be condisation from the winter months and starting it up, using mobile 1 in the cold or the dreaded head gasket. Looking for some insight on it or if anyone else has had this problem. Thank you guys
