1 quart in primary
22-24 oz. in tranny
3 quarts in engine

You can use,,,
Syn 3 by HD in all holes
Amsoil 20-50w for all three or buy 75-90 severe gear for tranny
Mobil 1 v-twin for engine...Redline for tranny...and amsoil for primary

What ever fluids float your boat..but the quantities are listed above. Do yourself a favor...get a service manual. The reason being...I'm giving you a Road King capacity for primary and tranny. I know the Dyna holds 3.5 qts. in engine but it would be smart to become a little mechanically sufficient. Get a manual.
