Restore oil additive...

some Yammie bits... note the dual-tract intake, where each cyl breathes through one tube at low rpms and both when wound out... pretty much wasted tech for me

That's absolutely insane there, having dual runners on the intake. But I suppose allowing only 1 intake valve to suck in the air at low rpms would increase the airflow speed and make the gas vaporize that much better.

I bet it sounds like a beast when it takes off at WOT. Not that you would know about that

No, it really doesn't. They're great engines, but they sound like poop. (Comparatively)

Intake runner length, and diameter make huge differences in where a motor makes it's power.
