I have a 2002 GTX RFI On take off it has a hard time until 3500 RPMS then it is all right I think it is the rave valves Changed the little valve by the motor also checked solenoid per manual says ohm out 30. Mine ohm out at 31.6 ohms. When I start the ski it reads 7.3 volts. Then I rev it up to 5000rpms and it reads 12volts Then I tried putting 12volts to the solenoid (rave) Does anybody know what else I can check because I think it is the rave valve. Thank you in advance
