Roger. As we have been discussing this for a good long while now, I simply cant help seeing some bias here. I mentioned that the stock bike had an upward of 18 afr as we spend some time driving on the dyno. You mentioned back then that was impossible. I saw it..... Here we are again, and you say it is an error. I say it is there, weather you like it or not ( not trying to pick on you....I am really not) but I trust the dyno, and the results it yields. You seem to put all your eggs in the gs-911 basket, but I will trust the dyno any day over the gs-911. I will admit to that you know more in depth, and the inner functions of the BMSK, than me.... hands down, but I think it is wrong to discredit dyno results that has been so clearly illustrated.
