I need some advice, so where better to go? I have an 06 banshee with...toomey t6 pipes - k&n no lid - advanced timing plate - boysen power reeds. I have a birthday coming and want to add some more, I ride with alot of 450's, we race and ride trails. right now everyone is really close in speed until extreme top end, that belongs to me at 84mph. I am not the lightest person at 255, and I also am not as experienced of a rider as some of the guys i ride wtih. I need the most bang for my buck!! What are the best mods that i can do next for under $500? Any and all advie is appreciated!!
