A few months ago dealer put Syn3 in motor, primary and Redline Heavy Shockproof in the tranny (at my request.)

This is a perfect quote! You nailed it on the head, and I agree!

17000 miles of Syn-3 in all three holes. No issues, no complaints. If I had the time and wasn't lazy, I'd change it myself and switch to Castrol Power RS V-Twin 4T in all 3 holes. $7.99 at O'Reilly's right now.

I ran Syn3 in all three holes for the first 15K that i put on my 2010 RK. But, just before the last change I started to notice a slight whine coming from the primary. When I talked with the service tech at my dealership, he said that they were switching out to Formula+ in the primary and tranny, but staying with Syn3 in the motor. So, I did that at 15k and noticed the whine went away, the clutch seemed to grab better and overall the motor seems to be much quieter.

I think the Moco (or somebody) changed the program. I think it is a good call on their part, I just wish it would have happened long before I had 15K on the bike.

???? are you saying switching your primary to formula + made your engine quieter??? As for the whine in your primary, I don't think the oil fixed it. You might have a inner primary bearing going bad. JMO!
