The difference between a FLSTC and a FLSTCI on a Harley-Davidson primarily lies in the fuel system and certain features. The FLSTC, or Heritage Softail Classic, typically refers to models with a carbureted engine, while the FLSTCI designates the same model but with electronic fuel injection (EFI). This change in fuel system enhances performance and reliability, particularly in varying weather conditions. Overall, both models share similar styling and chassis characteristics, but the EFI versions offer more modern technology.
The drain plug is located on the side of the transmission end cover (on the right side of the transmission) at the very bottom center.
Read the Service Manual....its not for beginners...you may want to consult someone whos done it before...some special tools are required to do it properly.
