This is the graph of four runs I did yesterday on the dynojet with the air fuel ratio. We did not discuss this much (I asked if it was good and was told it was fine); can someone explain this to me?
the first dip into the 11-12's is probaly the accelerator pump shot and then the graph leans out maybe a bit too much and then guessing the secondary opens up to richen the mix at 3600-3700. you peak power should be good but the mid midrange could be better. high 12's are ok for a dyno pull.
