bring the rath of the "anties" upon you.  L0LROTF.  keep up the good work...

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...
