I use the 20-50 in my Harley 103 and it runs quieter and smoother than Mobil 1. I use Mobil 1 in most everything but I like this oil in the Harley.
As you know I use Mystik JT8 semi syn 15/50 and I have so much of it I dont know if I will ever get a chance but if I do, the Valvoline Syn is a "I want to try oil" even though its not diesel rated for my bike, it sure looks darn close to a Diesel oil.
Always been a fan of Conventional Valvoline MC oil in past bikes, honestly and truly, never ran one bike with a full syn and would be curious ... I doubt I will ever get to that anytime soon I still have 1 or 2 years supply of the Mystik oil left

My bet is AW/ EP for the transmission. For what it's worth, you're right, I don't know. I wish I knew
