I just bought the bike monday so I dont know its history, the oil looked like sludge. It has 2700 miles an was laytd down at slow speed by the previous owner. I did an oil change today and the oil smelled a bit like gas. Also when it was draining the oil drops would bead up and roll down the drain. Is this odd or is it normal for synthetic oil or something? I only have a month left of factory warrenty.
