Dear Ralph:
I have a 2006 (early build) Crossfire 700 that won’t pull over 7300-7400 RPM. I’m at a loss of what is causing this, it was running really good and now this. HELP!

Sounds like the power valves are not opening. That’s about all the higher she’ll pull if the valves stay in the closed position. On the EFI models (like yours) the servo doesn’t cycle at start up like on the carbed models, so lift the rear of the sled onto a secure stand and run it up past the valve opening RPM (past 7000 RPM) and see if the servo motor cycles. Check to make sure the cables haven’t popped off or something stupid, if the vales get gummed this could happen. My guess is the servo motor isn’t getting the signal to open (a connector/wiring issue) or the servo motor itself went south. There is a position sensor inside there that could’ve went bad, so if the motor (pulley) doesn’t move at all after reseating the connectors try a new servo. If that doesn’t work, you’ll have to verify continuity from the ECU to the servo. I doubt it is an ECU problem, it’s either the servo or the wiring.
