Blockage in idle mixture passages on carb #2 would be my guess.
Have you synced the carbs? I would try that and see what that shows you. If there is a problem it's going to take significant adjustments to get them close. At that point it's showing you they need to come off and be gone through. |

Float levels should also be checked, as well as removing and carefully cleaning all the jets and other passages. |

it seem my bike will have different vac pressure when throttling from idle position. possible butterfly valve leaking/gap or pilot jet or something else that i'm not so sure.
Done idling manometer check and settle for now. |
