    kfx400 carb problems

    About 3 months ago I braught my quad to the local honda dealer for them to jet the carb for the exhaust that i got. At first it ran amazingly but then there were problems. Such as when you started it and gave it gas it would bog down and pop. This is the third time that it has happened and i was wondering if i should just keep letting honda fix it and have inconveinent problems or if it is the whole carb that is wrong and that i should invest in a whole new carb. Or if there is something else that one of you have an opinion on. If this has happened to you or you have heard about it ide be more than happy to hear you opinion.
    Thanks,
    Andrew
