I am thinking of getting a Banshee that is trashed. My plan is to rebuild this into a keeper quad that is reliably fast. So here is my question. If I bore the stock sleeve 80 over and put the 5mm longer rod into it how big is this going to be? What are the best mods that make the best results on these quads??? We want a fast reliable Banshee for sand dunes & ice racing / maybe even some Hatfield McCoy trail riding also.
