When the headlight is on it switches extra coils in generator into charging circuit.
 At idle, it's still charging at half an amp with a 35w bulb 'burning'
Half amp at  nominal 12 volts is only about 6 watts (really closer to 6.5 watts)
 It means you cant run more than a 40 watt bulb without flattening battery, 45 watts will be OK as long as rpm is always above 3,000.
 If you fit a 60/55w H4 bulb, you will have limited riding time because generator can't produce enough power, even at high rpm

OK, an update.
 Brendon's bike charges at a slightly higher rate than mine.
 He's been using a 60/55 H4 bulb for several months without any issues.
However, he does rev the hell out of it  ;D
I re-did ground lead (fitted an extra green wire to center of rectifier mounting bolt and cleaned frame real good around toolbox mounting bolt)
 It's working real good (good enough for him to fall down yesterday  ;D )
It was in gravel at about 5mph though
