YFZ450 Jetting specs

Does anyone have information for the jetting specs of a 2006 Yamaha YFZ450 with a Motoworks SR4 full pipe system at sea level.

Lots of people reading this, but no help so far. Someone out there must be running a Motoworks pipe on a YFZ.

Maybe one of the Motoworks/Can-Am race team has a hint?
