Repair manual says to fill engine with 3 1/2 qt. if oil has been drained. Not so! Start out with less than 3 qt. - check oil level and fill a little at a time until level is between marks on dipstick. Should be at "full" mark when hot - not cold.
I just tried to pour 3 1/2 qt. into tank and it overflowed. Needed to "turkey baster" the excess out!
To answer your question......Softail manual states the following with the bike upright:
Primary - level with the bottom edge of the clutch diaphragm spring - approx 26 oz.
Engine Oil - I usually add 3 quarts of oil to the oil bag. Warm up the bike and then fill to upper grove of dipstick. However, I keep it a little below that line.
Transmission - Lubricant should be at the (F) Full mark on the dipstick. Dipstick should rest on the lip of the filler, so don't screw in.
Now, you'll get a lot of different opinions on what fluids you should use. I will not recommend anything, but tell you what I use, and I have 105,000 miles on my bike. For the engine, I use Mobil 1 15w50 synthetic motor oil. In the primary, I use conventional Pennzoil 10w40 oil. And finally in the transmission, I use Redline Shockproof Heavy gear oil.
