125-200cc 2002 husqvarna wr125 spark problems

I have a 2002 husqvarna wr125, was running good then lost spark, put a new coil and, had spark for a bit then I lost it, changed the ground, then got spark again, ran good and now nothing. Pulled the stator/ generator or whatever you call it. Cleaned it all up, and now all I get is power to the front and rear lights when I kick it over. No spark or whatsoever. I am at a loss with the bike. Any suggestions or advice would be greatly appreciated

Have you checked the plug cap. I would try changing it before going any farther.
