Yup, hard starting and accelerating from idle is mixture screw adjustment, not mains. And you're right about leaning out high-end for more power. Here's dyno chart with all mods using factory jetting, way, way too rich.
This is before going down to 96 mains, and even then, still too rich. An article where they went down to 95 mains after AreaP full exhaust upgrade (scroll down to "Nuts and bolts" section).
