Can't make it street legal in Missouri. Only legal to ride on county dirt roads. I only asked about nos cause I haven't heard of anybody on here talking about it. Not looking for black magic motogeek. Just looking for things to make my 86' a little different than what everybody else has or is doing.  If I were to install nos, it would be a mild shot to get me up a sand dune a little faster or to drag race my brothers banshee and hopefully put him to shame. His shee is purely stock and heavy.
