i just bought a pro flow kit i was just wondering what main jet size should i run if i take the lid off? My twist throttle can with 220's and 240's and i belive 160's. i tried it without changes iszes but it would bogg out around 1/4-1/2.so what do u guys think 220's or 240's.the bike is completly stock.

1/4 TO 1/2 IS NOT YOUR MAIN JET! I WOULD CHANGE YOU CLIP POS FIRST
