Does the OP want a carb that he can just bolt on and go with little or no tuning?
If that is the goal and 750 CFM is the target size, then the Street Demon 750 is the absolute best carb for him. The tune is as good as anything on the market for his preferences and it has design features that no other carb on the market today has. Features that matter and deliver real driveability improvements.
