You have to consider the size of the idle air bleeds and the main bleeds.
What you guys are getting into is as complicated as jetting Webers but you can only increase the size of the air bleeds (air jets) since they are pressed into the carb housing.
Try a 750 DP out of the box and see how it idles and runs.
72-73 front, 76-78 rear should be about right.
If you need more in the rear you might want to consider a secondary power valve with a real late opening like 2.5 or 3.o.
