When I called the dealers before, the service guy didn't think it was right that they just fall out so he asked a technician who also thought it strange. Then I got put onto the service manager who agreed and said to put it back together and bring it in as soon as.
As far as I'm aware, the ideal mixture is 12.6:1 for power and 14.6:1 for cruising. That is, you'd tune your pilots and needles slightly lean for economy when you're cruising but when you wanna 'get it on' and crank the throttle, bringing the mains into play, you want 12.6. The top line of the A/F chart above is 11.6, which is very rich and the whole curve is below that figure. It drops to 10.3 in places, which is soopa-rich. With my set-up, it *should* run lean but the plugs, the pipes, the dyno and the way it rides all say rich, hence I'm taking it back to the dealers.
A/F ratio. Basically, the bigger number represents the amount of oxygen molecules to every fuel molecule. Therefore, 12:1 is richer (less oxygen) than 14:1.
