First, congrats on the new scoot. SG's are sweet machines.
I don't run the same setup as you; I've run Amsoil before when my dealer did my 1k service for free, but have since moved on to other things. In the last 4 years I've run:
Engine- HD360 dino, Amsoil, Redline, M1 15W-50, M1-V Twin, Syn3, and Valvoline VR1 racing dino. Finally settled on VR1 dino based on positive UOA's in other TC Harleys and considerably less valve tick than with synthetics.
Primary- Syn3, Amsoil MCV 20W-50, Redline MTL, Formula+, and Rotella 15W-40. Ran Formula+ for 3 years till last oil change as it always gave the best clutch feel for me. Switched to Rotella last oil change as it's 1/4 the cost & clutch feel is identical to F+.
Transmission- Formula+, Amsoil gear lube, Syn3, Redline Shockproof Heavy, and Spectro Platinum 6-speed transmission oil. Settled on the Redline SPH as it quiets the tranny 5th gear whine the most and has the least amount of debris on the drain plug.
You'll probably try all kinds of oils looking for that perfect combination- most of us do. Enjoy the quest and most of all enjoy the new bike!
