    Carbs Coughing at 1/8 throttle

    Hey guys if i could get some opinions on this that would be awesome... When im riding at anypoint when the throttle is on really lightly the carbs start to *cought* like this wierd sputtering noise but if i give it gas it goes away and if i let go of the throttle completely it goes away... From what i understand/researched this is a LEAN symptom? i went up on the pilot jets to see if it would improve and it did and it sounds/rides a lot better in low end rpms ranges, but the occasional cough!

    Pods/Vances Hines 4-1
    120 main jets/ 20 pilot jets
    Fuel screws are turned out 1 1/2 turns and air screws are double...

    My only thought left would to turn the fuel screws out 1/4 turn... any other thoughts or experience? thanks for reading!!

    I'd start by turning the air screws in 1/4-1/2 turn and see if the pilot circuit richens a bit.

      I agree with Dave - your screws are at the outer parameters as set, turn the air in 1/4 turn

      I wonder if this is a pod issue?

      What brand of pods are you running? Oiled?
