FCR Carb setup

Charlie had the jetting changed and the carb tuned very rich for the 25% ethanol content in the Brazilian fuel. I'm told running it rich is the best way to start it that side. Any comments/pointers/advice on how to fiddle the carb to run on this stuff would be most welcome. I believe the carb is exactly the same as the KTM 450 so I guess I'll need to play around with mine in Lima for a bit. Does anyone have a good link for a noob to learn a bit more about this?
This is a good resource for learning about the Keihin FCR carb. I doubt there's any information on jetting for 25% ethanol though.
