    Sounds like you need to upjet the carb, and remember youre still running it in ?

    SO take it easy, or youll blow it up

    yeah start off on a 10% upjet, what mainjet size have you got in your carb?

    delly 21mm carb ?
    try a 92,93,94,95 mainjet size
    Buy a jetbox, would be easier

    revving high should be your over high idle
    and spluttering and 'coughing' would be fuel/air mixture

    Upload a video for us to see
