Oh, yeah, but isn't this thread about using more fuel when you've got P
plates on or something? I don't remember.

A field coil based one, so nothing much like a motorcycle[*] one anyway.

Hey, guess what? After all that it looks like the XLV regulator might
be a shunt design after all ... Honda, 1986. I can't work out _WHY_,
though, because the power part of the design they've used is actually
_MORE_ complicated than the switch-mode design I posted the little piccy
of the other day, although maybe the control logic is a bit simpler.

Also the air is slightly cooler (on average) at night, so engine is
more efficient.

<reluctantly> Yes Hammo, on that one you and Nev are right (although
there's a whole heaps of if ands and buts to add to that statement. I
got 3 lines into responding to the GB/Nev thread on that and said
"stuff it")

His results are indeed repeatable. That doesn't mean the principle
under discussion is wrong, just that the test isn't providing data
that will allow a the different options to be eliminated(1). More
testing required.

(1) Yes Hammo, I'm short cutting a discussion of hypothesis testing,
methodology etc not relevant or useful

It's also more dense, thus increasing drag.
