Ok, I have searched and I am overwhelmed. I have never owned an HD before but have completed numerous oil changes on bikes. Can someone tell me the capacity/weight of oil to use for oil change, primary and transmission. If you want to provide suggestions of brands, I'll gladly listen. I do not want to buy HD oil though. Thanks in advance. I guess it would help to get advice on capacities if I listed my bike, 2007 Road King.
