I have a 2006 (early build) Crossfire 700 that wonâ€™t pull over 7300-7400 RPM. Iâ€™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. Thatâ€™s about all the higher sheâ€™ll pull if the valves stay in the closed position. On the EFI models (like yours) the servo doesnâ€™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 havenâ€™t popped off or something stupid, if the vales get gummed this could happen. My guess is the servo motor isnâ€™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 couldâ€™ve went bad, so if the motor (pulley) doesnâ€™t move at all after reseating the connectors try a new servo. If that doesnâ€™t work, youâ€™ll have to verify continuity from the ECU to the servo. I doubt it is an ECU problem, itâ€™s either the servo or the wiring.
