    I want to start changing my fluids on my bike.
    Whats the best synthetic oil to use and weight. Also for the primary. Is the transmission seperate with its own plug?

    Hello and welcome! I suggest you search the forum for "engine oil", "transmission oil". etc... You will find tons of opinions. That being said I have a 2012 FLSTC and use:

    Mobile 1 V-twin in the engine
    Spectro 6-speed in the tranny
    H-D formula+ in the primary

    So far, no problems for me and I can tell you that the transmission shifts smoother now and is a lot quiter.

    I think quite a few people on here use this combo. Amsoil and Redline are also popular.

    The above seems to be the most popular combination among forum members. It's the one I've been using for 5 years.

    This is the combination I use right now but I have used AMSOIL in the bike now and then.
