I owned shovels prior to getting my 08 Fatboy. I was pretty handy and could do rebuilds and about anything else I needed to do. I figured even after a hiatus changing the fluids on my Twincam was no big deal. Got everything together, read the manual, looked at the "Fix My Hog" DVD and started. So the whole oil drain in the "swing arm" messed with my head for hours. I kept looking at the Dyna / Touring picture of the drain plug. I ended up removing the "never under pain of death" do you remove the 2 plugs on the bottom of the engine case. They came out easy and after realizing they were the ones I read of before that a lot of newbies attempt to remove and cracked the case in the process I about died; then I was a little perturbed at how easy they came out. I put a little blue loctite on them and put them back in; not sure about torque so I put them at a good set with a short 3/8 ratchet. Anyway I used Mobile 1 V-Twin in the engine and Spectro in the tranny and primary. Can't believe how much better it shifts and sounds and about 10 PSI increase in oil pressure. Hope it runs a little cooler too.
