If the calibration is the issue with the xp line, then that's not a big deal as I would be recalibrating the carbs for the t ram. I thought there may have been an issue with the venture design as well?
Depends on the model. The "950" w/ the 1.60" venturi seems like a step backwards, based upon Mark Whitener's battery of flow bench testing different carb body & booster styles. However, the smaller carbs are better. The one pictured started with an "850" main body having a 1.56" venturi.
