first make sure you have no intake leaks at boot or from airbox to carb

it sounds like you are lean since the throttle goes up and down when steady like surging almost that means you have to modofy the needle position or needle and mainjet

do one change at a time

Im using on my bike(dual headers and different jetting)

15 pilot and 230 main
needle 3rd clip or middle

its perfect now. nice and tan brown on the plug and no hesitation, bog or surging anywhere
