    Mikuni Carbs

    Hello everybody! I am working on straightening out my air fuel ratio. I am using a wide band a/f meter. The bike idles at 14.7 to 1 with choke(terrible without), but as soon as I touch the throttle it leans out up to 18 to 1. The bike is completely stock. My metering rods in it only have one notch. So I haven't tried shimming. I've played around with pilot screws. With no success. Where should I go from here? I did take the rubber manifold off and checked out o rings. I haven't used any brake cleaner to check for any leaks yet.

    First place to go is back to your signature and fill in what bike this is..for us to help you better answer your question and to prevent others from constantly asking you what bike it is.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

          You can only change the fuel to air ration at above 1/4 throttle by rejetting. Need details..and preferrably some pics also..of the exhaust and airbox setups. these details are crucial for an educated accessment of what going on. And at the top of the Carb section here, youll see STICKYS. Choose the one on CV carb tuning.
