fi code 25

  1. FI Code 25 - Runs Okay - Right Knock Sensor

    GL1800 Tech Board
    I bought a 2001 GL1800 with 200,000 miles--12,000 miles ago. It runs great but burns a bit of oil. I started getting a Fuel Injector code #25 on my last ride. It indicates a right knock sensor circuit problem. I have a service manual, but have no idea how to start on this issue. Any help...
