There's a thread on here somewhere that shows a bunch of VM set ups that have worked (all based on each person's location, bike configuration, etc...) which boils down to each bike is different and what works for some may not work for others...that being said, there are a few common traits that seem to be consistent. The biggest one I saw was that most people ended up with pilot jet's being closer to 25... I copied this summary for my own purposes when I went to VM carbs this year... it helped me get a general starting point and what size jets to get in anticipation of tuning needs. Here's the list I came up with (Again, stolen from a thread which actually has a lot more info, but condensed for my purposes). Might help you as well:
Mikuni VM combos
MJ = Main Jet
PJ = Pilot Jet
NJ = Needle Jet (emulsion tube)
JN = Jet Needle
Slide = Cutaway number
