Well you mentioned all the possible problems. What have you done to troubleshoot?
I would disassemble the starter switch first, since that is frequently the issue. If that is clean and has good contact you need to find the connector some were around the radiator I think on your bike and make sure it has good contact and is not burned.
If both prove not to be the problem, report back.
And then consider to order a headlight relay kit from eastern beaver, if he offers one for your model, not sure.
