Just bought a banshee that I’m trying to figure out what route to go with, looking to build a decent dune bike that’s capable of kill climbs but not looking to touch the bottom end yet. Looking at stock bore or something mild. Don’t know what carbs, head, jugs or dome, not sure on anything. It previously had 66mm pistions in it running on a single quadzilla carb. Other than that I have no clue what is done to it. Looking for advise how to build this
