Starter spins with no motor connection, and won't stop spinning unless I disconnect the "S" terminal for a second or so. I figure that the former means getting a new sprag clutch, and the latter means, possibly crappy starter contacts in the handlebar switch, or?

I would think it could also mean that the Relay is not re-opening like it should. The "second or so" in your description seems peculiar. Do they specify that the device is supposed to be mounted in some certain way?
Could the solenoid be relying on power going through the switched contacts to provide a reverse magnetic field to reopen the contacts. Just speculating, I've never heard of a design like this.
but if that was the case, the reduced amperage demand of the smaller starter motor could inhibit the contacts opening.
What is the 2nd small terminal on the starter relay supposed to be for?
