Hello Folks,
What size Jets (slow and main) should I use for a 250 with only exhaust and intake modifications? Intake is a foam type and exhaust is a DG Performance RCM Steel exhaust.( Very loud) Any guidance would help! My guess is 40 pilot and 128 main but I have a feeling that is still too small.
