I am getting ready to change my oil for the first time and this is my first Harley. Do you guys think I should run 10w 40 for the winter. I live in Va and the morning temps have been around 30 and it gets about 50 most of the time until a month or so when it will probobly have a run of 30's or 40's. I still do ride, not everyday but I do not "store" my bike for the winter. I will ride unless there is salt or sand on the road.
