Guys that can run 3 circuits on the street with no fouling issues is amazing.

No way these out the box 3 circuits can run clean @ tip in , as soon as the throttle blades are cracked open fuel will pour in below the boosters , i'm gonna bet anyone running a 3 circuit out the box with no modifications to temporary block the intermediate tube with a tooth pick or similar & then post back hoe that little ole mod made the world of difference.
