While on the stand my King Cat won't rev past 6500 rpms. Servo is opening the power valves but seems to fall flat at 6500 rpms almost like its missing at the high rpm's, any thoughts?
on the stand there is no resistance for the clutching to do its magic. If you grab a handful of break are the clutches moving in sync while your on the throttle? If so then I don't have much to offer being that you have an EFI and I only know some about the carb version. Maybe throttle sensor if you have one.
