Woops, after a second look i think the rpm axis index labeling got cut off on that image. If you look at where the torque and rpm cross (5252 rpm), then you can count the bars from there. Really it looks like some power is lost below 2700RPM, which isn't that big of a deal in my opinion. If you are trying to go fast, racing or whatever, then you be above 2700 RPM 99% of the time anyway.
Oh if you mean the other blips on the torque(which actually show as gaps in the power graph), I think the inductive ignition pickup was getting some interference or bad reading, but if you look at the rest of the graph it's pretty clear where the curve really is.
