Engine oil: 3 qts 20w-50

You'll get plenty of opinions on which fluids to use. Too many opinions actually. Harley fluids for the tranny and primary are fine. I'm using ATF in my primary and RedLine Shock Proof in my tranny. I'm a fan of Mobil1 and use it in my car and my RoadGlide's engine, but would not use it in the tranny. Pick up a decent 75w-90 or 80w-140 gear oil if you don't have access to RedLine products where you are. Quite frankly, just about anything is OK in the primary. You are probably fine using the Mobil1 in there if you choose.
