It would make sense that if the bike isn't heated and it's -3* ... The seals on it may have shrunk and leaked. Also may have just a little moisture up inside, that is frozen between the seals and metal. I had an eom pet **** on my 86' till about a year ago. It was so worn out you didn't dare turn it to reserve or you would be walking home. It's safe to say it put in its time. LMFAO
