Hi, headlights turn off when power on and bike wont start.
Hi, headlights turn off when ignition swight on and turning handlebars side to side, when the lights go off the bike will not turn over or start. Re-positioning handle bars will turn the lights back on and power to the starter and the bike will turn over. Any thoughts?

Sounds right to me. Follow the wire from the ignition switch. ie. the acc wire (one wire) should be getting power. That wire powers the radio circuit. i suspect it it feeding the or an ignition power circuit now.
If the starter turns, but there is no battery power reaching the headlights and no battery power reaching the ignition system there is a fault in some part of the electrical system used by both headlights and the ignition system, but not the starter motor. Check all the fuses, if any are bad or dirty replace them then try again, then check the new fuses to see if they have 'blown' if they have you have a serious short-circuit in the wiring or other electrical component, replace the fuses again and remove all the headlight and tail bulbs and try again.
Unless you have something "custom" on your bike, the "HI/LO" switch is on the right handlebar switch housing. The main ignition switch turns on the headlights. From the factory, when you turn the ignition switch on, the headlight automatically comes on as most states require motorcycles to have their headlight on at all times when on the road. Now, some riders modify the wiring so that they can start the engine without the headlights on thinking the additional current will start the engine better. Once started, they will turn the switch one more click clockwise for the lights. I think the late models have an extra click before it goes to the "accessory" posititons. The older ones do anyway. I'm pretty sure the later models are the same way but I can't say that for certain as my expertise goes up though the '90's models. I do not work on the twin cam powered bikes.
Are you certain you are not turning off the emergency shut off switch usually found on the right hand side of the handlebar thinking it is the headlight switch, are you? You don't mention the model nor year.
If you are in the US market of have a US market bike, many late model US market motorcycles don't have switches for headlights as headlights are required to be on if the motor is runnning.
I hope this is your trouble ...

If the battery is in good shape and fully charged - and the headlight fuse is not blown, then I suspect that the starter button is at fault. The starter button does two things when you press it: engages the electrical circuit that causes the starter relay to trip, and, at the same time, cuts power to the headlight.
It could be that the contacts inside the handlebar mounted starter button are dirty. You can try spraying some electrical contact cleaner in there - but you are likely going to have to replace the whole right side handlebar switch assembly.
Check the ignition switch. The headlight power runs through the ignition switch, and this turns off the headlight when the starter is engaged, which provides full battery power to the starter without the load from the headlight. If there is damage to the starter button, it may be shorting out and causing the problem.
