I had a strange idea.....
what it consists of, is modifying the right hand crank case cover, and then mounting a small car alternator above the gearbox, behind the cylinder.
then instead of the rotor on the crank, mount a pulley for a belt drive to the alternator.
a custom plate for the points/etc ignition would be needed, but that shouldnt be hard.....
it would lighten the crank a bit (making it a little more free revving), the regulator/rectifier would all be sorted as part of the alternator itself, so the wiring loom would be a bit simpler as well....
you can get some very small alternators (20 to 40amp), so additional devices (heated grips, heated seat, etc), could be used, without worrying about draining the battery/overloading the standard alternator.....
just a random idea.....anyone think it would work?
or already done it?
