That high mileage stuff has friction modifiers in it. Why would you want the friction plates in your clutch to slip? And the seal swellers in it can make the friction materials swell and actually let loose. Not a good idea.
Rotella for deisel engines is my go to for shared sump engines. Water or air cooled.
Read about additive packages and think about your application and you'll see why.
If you insist on mobile one, they make two oils specifically for motorcycles with shared sumps...
"4T" and "Vtwin"
Water cooled and air cooled respectively.
50/50 just means pre mixed
You need the coolant bottle to say "safe for aluminum"
That spline lube should be just fine.
Lithium stays put till melted and the "Molly" makes it slicker
The 80/90 sounds good too
It's marked "Hypoid" gear oil, right?
