I recently bored my 06' banshee .90 over and i cant get it running right. I have boyelson reeds, barnett dirt digger clutch, stock carbs w/ air screw carb kit, dmc alien exhaust, boost bottle, and k&n air filter. Before i recently bored it i was running a 280 main jet. I tried a 340 but it is not runnig right at all....???? What jet size should i use and should i also change the pilot size?? Also i wanna buy a cool head.....what brand should i go with?? What size domes??
