Is the rectifier/regulator all I would need?  $10-$15?  You bet, I'd try 
one!

I'm thinking about a voltage dropping device(adjustable?) in the headlight 
circuit for daytime use that would still keep me legal but drop wattage to 
20 or less, and be easily switchable for nighttime use. Could even be 
pulsing for greater visibility. I ride almost exclusively in the daytime. 
Any ideas?

No bike, to my knowledge, had permanent magnets on the rotor in the early
1980 years. At that time, ferrite magnets, the only available ones in
automative market, were too weak, and SmCo magnets were still to be used in
high torque motors, like for aeronautic and space applications. SmCo
magnets, the only ones which can whistand >100°C temperatures in a bike
alternator housing, are now available at reasonnable prices.

You are right, a magneto system is another solution as well, but needs to
rebuild the whole alternator. I thought even to take the alternator of a
Vtwin Ducati and adjust it to fit inside my NH housing. Unfortunately, it
would rotate too fast (19 000 rpm) and probably explode. The solution that
I propose is just a refitting on the rotor, keeping the existing rotor
minus the excitation winding. I have a proposition of a chinese
manufacturer for a rectifier/regulator at less than $10 !

Anyone interested in trying ? The challenge of getting a nighthawk with a
REAL charging system - not a flawly designed one - doesn't find any echo ?
I'm in the position now of making the efforts to make the thing, or sell
this f... bike to somebody else. I suppose - laugh - that most of the
nighthawks for sale are sold because owners are sick of the charging
system. Except of course some lovers of this bike who never ride it with
the headlamp on and/or in hot weather and/or in city jams.

I came to understand that in the south hemisphere, there would be no
problem. Interesting... could be due to the Coriolis force... or the hole
in the ozon layer in the atmosphere... or the problem could perhaps be
solved by wearing a shirt with a Honda patch...
