hi i have a common mikuni flatlslide 28mm carb on my 200x, it runs great with it, increased power overall a bit. problem is it bogs on whoops, big jump landings and after long wheelies. is the pc racing vent system the way to go? i saw a boysen super bowl in some magazine i think too. any options out there that work.

also my jetting looks correct on the plug, runs good just hesitates on the 1/4 throttle transfer from pilot jet to the needle. ive adjusted the needle up and down but mid postion works best (least bog on transition) should i try replacing the pilot jet? i dont have much experience other than the main jet for top end, which is fine on it

thanks!
