Do i need a stator rewinder for my dirtbike?

What i was thinking about doing was turning my dirtbike(Honda CRF150f) into an enduro or a dual sport. I need a lighting kit. Turn signals, brake light, headlight, horn, rearview mirrors. etc........... But to install, the website says i need a stator rewind? What is that? I've never heard of it. I would appreciate it so much if somebody told me what it was and maybe how to install it.
