As an Amsoil dealer let me offer these suggestions. For the crank case and primary use this: MCV 20w-50
For the transmission use this: SVG 75w-110
To get the most from your crank case oil use Amsoils "nanofiber" oil filters. It's a completely different technology than other filters. For example this Amsoil's EaoM 134c, which will fit most Harleys from 2001 and up:
I know it looks the same but the difference is HUGE.
