my buddy has an 04 Dale Jr Pred. He removed the air box completely and has installed a K&N. Stock carb and exhaust.
He has tried a 170, 180, and 190 and it still feels lean, and labor knocks a little. Should he try a higher jet? I've tried to get him to do a plug check, but he says he doesn't feel safe running the quad because of the labor knocking and how it feels. He's ran the needle at 3rd, 4th, and 5th notches with no change.
Thanks
Travis
