Good To Know

Q: Does this fit my 2002 GTX RFI 800? A: The listing covers 1998 through 2002 GTX RFI 800 machines, so confirm your model year and serial number before ordering. A quick check against your parts diagram avoids a return.

Q: Do I need to reset anything after installing it? A: Adjust the cover screw to the setting your service manual lists for the RAVE valve, then verify the valve moves freely. Small changes in position affect exhaust timing, so make one change at a time.
