Help! '00 Mille Running Rich

What can I do to get my bike a little leaner. My bike was dynoed at 98 wheel horsepower before it was wrecked and rebuilt by myself. It had a full D&D exhaust that was ridiculously loud. Other than that it was just derestricted with the wire cut mod and airbox plate removed. At that time the guy said it was running pretty rich. Is there something I can do to adjust it without the Evo fuel pressure regulator or do I need that? :dunno
 
depends where it's running rich.

You can adjust the tb's for idle and 1st 1/3 throttle. After that you need mapping changes either by eeprom or pc3
 
The idle is good but the guy running the dyno told me he could smell how rich it was and that with it slightly leaner than it is the bike should have better power numbers. More around 3rd gear. Also would a PowerCommander fix that and could I map it to provide more fuel during the dreaded 4k flat spot before I get the header mod. I know a dual exhaust helps get rid of it but that's just too much money since I just got married.
