i have a stock banshee with ptr mids and a k&n filter in the stock air box no lid around 1500ft. elev. just put the trinity 35mm stage iv kit on and jetted. i ended up with a 175 main and a 42 pilot needle in the 2nd postion from the top and air screw 2 turns. it runs good and plugs look good but from what i've seen on here i should be closer to a 185 main and a 50 pilot. i am also surprised how sensitive these sons a bitches are. with a 45 pilot it fouled plugs constantly but go to a 40 and it was popping from being lean. i'm used to jetting cars they aren't near as much of a pain in the ass.
