I went to a local dealer to buy jets and the guy told me that 330 mains were way to big,and to just use stock 200 mains.I told him that with my mods I needed the 330's and he said mods don't matter and if a Banshee needed 330's Yamaha would of put them on at the factory.He sold me the 330's I wanted,and told me not to come back and complain if my Banshee wouldn't run.Man I love dealers!!!
