    Download the shop manual and fully read Section 6 Sub-Section 03 Fuel (carburetors) for proper carb rebuilding and tuning:


    If you are running the engine completely stock and you are using the stock air box. Both carbs’ Low speed adjustment screws should only be opened(counterclockwise) 1 1/4 turns and the High speed screws shall be fully closed(screws turned clockwise until lightly seated). During carb adjustments with the pump fully loaded on the trailer under idle. The engine shall have a crisp and quick response to the carbs’ adjustment screws. Any low speed screw adjustment shall only be turned 1/4 turn at a time during each test.

    From what you describe while out riding it. It sounds like it’s lean and the low speed screws need to be opened up 1/4 turn from where they sit now. Re-adjust both low speed screws and re-test. Continue adjusting until the engine doesn’t cut out(lean) or just lug along(rich).
    What would Chuck Norris do?
