The best way to get the correct color code is to call a Harley dealer. Have your vin number and talk to the parts people. They can give you the color codes for that bike. The black is a Vivid Black 98603 DH but I no idea what you're talking about with the "champagne".
PXR is the color code for the paint color of the vehicle. If you take that color code to a auto paint supplier they can match the color exactly. I believe that is a Jeep color code for Brilliant Black Pearl Coat.
PX8 - Black, Clear Coat
Trouble code P0133 means:O2 sensor circuit slow responce (Bank 1 Sensor 1)
