ok i have a 2005 yamaha banshee that is pretty much stock except for fmf fatty exhaust, gutted fmf powercore 2 silencers, pro designs pro-flow k&n intake system with outerwares, scary fast power now valve, and no air lid. i run maxima 927 castor oil mixed 40:1 with premium gas. My main jet is 300 and a 25 piolet, my bike will boil over from the radiator after running awhile and it bogs down when i take off easy. my elevation is 25 feet and the temperature is around mid 80s to around 100 fahrenheit but right now the wheather.com says its 94 and feels like 108. I also have a carb sync tool if that helps any so could someone help me with my jetting like what size mains and piolets?
Thanks
