Thanks Pablo, the lower TBN isn't a problem since I usually change the bike oil at 2k anyway. All those transmission gears grinding away at the oil always worries me, plus I've got so dang much oil in my stash now targeted at that FJR it's silly! (Lucas MC oil, Delvac, RTS, Motorcraft 15w40, and now Amsoil Scooter oil!) I'm gonna have to ride this thing a long time!!!
I've always been amazed at guys who will run motorcycle oil 6k or 9k miles... if a motor chews up oil over time, how much accelerated is a five or six speed transmission going to shear it down?
Sounds like the Scooter oil will do well in my FJR! I bought enough for two changes.
