I just did this to my cb125 I bought a cb360 stator for 20$ on ebay, it fits right in place of the other. Then I used the wiring harness/stator plug from the old stator. then I upgraded the rectifier for 5$ at radioshack. I use napa 5006 headlight bulbs, they fit pretty well in the headlight bracket. I just pressed them in, I don't mount them with screws. they don't move at all.
