The sled is a 01 mxz 700 with DPM. Its running pretty rich at WOT. The mids are a bit lean though on the EGT gauges, wash looks good, more on the rich side, plugs show the same. It currently has 520 mains. Not 520N mains. Needles are stock with only the 1 stock washer. I wanted to jet it down by 1. The service department said that 520's flow like a 490 so i would need 480's. Does that sound right?
