i tried using the search function but it wont pull anything up for me. I need some help on my jetting, I'm at 1000 to 1100 feet above sea level, all my mods so far are tr-6 pipes, v-force 3 reeds, advanced timing at +4, barnett racing clutch, k&n air filter with pro flo adapter plate and the air box cut off. Right now on my stock carbs i'm running at 280 main and the needle at the 3rd position. I'm thinking i should be running a 340 main and the needle at the same it is now, does that sound about right? I will do a plug chop in the next day or two but i wanted to get an better idea of where i should be before i do a chop. thanks guys. oh yeah, forgot tors removed.
