FULL CT SONIC KIT, 170/175 JETS, K&N W/ PRO-DESIGN AND NO LID. STOCK PILOTS...3RD CLIP...2 1/2 TURNS OUT...CENTRAL KY...ABOUT 500FT.

What size needle jets? I am running 160/165 mains with 25 pilots, #95 starter jet, and I don’t know the size on the needle jets but they are in 6th clip and when I hit any where between 1/2 throttle and full it wants to fall flat on its face? Running K&N filter, box and snorkel, with after lexx Mxe power core exhaust.
