The charging system is probably not up to it. I dont know anything about your model but as far as the major jap brands go if they dident come with lights or a starter from the factory the stator does not have enough output to run a headlight. For some brands you can buy a higher output stator and some brands you have to get the stock stator rewound (more windings = more juice) search the web for stator rewinding. Or look around locally a shop that rebuilds electric motors, starters, or alternators. Any business that does that should be setup to rewind a stator.
