To me it sounds like your mains are a bit to small. 1/4 to 3/4 throttle is controlled by the needle, WOT is controlled by the main jets.
I'm running pods,pipes,ported stock cages w/boyesen reeds and i'm running 320 mains 3rd clip 27.5 pilots and a tad lean on top because of the temps here, but I havent had a chance to get her out this winter.
Aftermarket reeds will make a big difference on your throttle response for sure, my ported stockers made a noticable difference. VF3's I would imagine are better ten fold.
