I've got a few questions. I don't know squat about dyno charts but someday when the money is in I want a torque cam and some headwork since I ride mostly under 4000 rpm. I will have to wait on the miles to wear some before I do the big bore kit.
1. If he got a dyno evidently they did not get it quite where it should be. So if a person had a tuner like say TTS then you could do you own modifications to it IF you knew what you wanted to change. But otherwise I surmise you would have to go back to the dyno and hopefully they give you at least a discount rate for the correction?
2. It's easy enough to read the charts that you showed but how do you determine what is too lean at WOT and how do you arrive at 12:1 or 13:1?
In other words is the dotted line air or fuel and what is the ratio to?
