hi can anyone tell me what to do to eliminate battery lights etc to strip down for dirt riding only,,,,

Why, its designed for off road work as it is, unless you remove the various components completely and with good water/vibe protection stripping it all off saves you nothing. One day you will be on the dirt in the dark and wish you had the lights.

Losing the ig switch is the only plus for a pure dirt bike but no one will relay that info in a public forum.
