I have a stock 08 and have a b-limited pipe,flame arrestors,pump cone,new bars ,primer kit and foot holds coming. I want more low end than anything as I am 230lbs and more into jumping, recreational riding,frestyle type riding. What head would you rec. for pump gas but more power and any other suggestions , also what about carb tuninh will I need to go bigger on jetting mains/pilots ? Thanks for the help this ski is bone stock and needs more power but still a blast !!
