I have done a lot of "Googling" and found a lot of conflicting information. As a result, I figured I would find a Harley-Davidson forum and seek the wisdom of experienced owners. To be clear, I'm not asking about what brand I should choose and I certainly don't want to do everyone a disservice and start a conventional vs. synthetic war. I'm merely looking for the types of fluids required.

I know that the engine oil should be a 20W-50... that much is pretty clear. But I'm a bit hazy on the Primary and Trans.
Welcome to the forum from central Texas, Chris.

There is an oil related subforum. It will tell you what fluids are most popular with members. Although it will indicate brands, it will also tell you the type of fluid used in the engine, primary and transmission. Look at the different "Sticky"'s at the top of oil subforum.
