GP1300R RPM Drop
I have a 2003 GP1300R. To give you some history. I had the Riva cat removal kit installed including the EFI controller. No other mods. She had the top end rebuilt 60 hours ago. There are about 260 hours on her currently.
Last summer I had the service engine light come on twice. Took it to the dealer and they could find nothing wrong. Now when at about 3,000-4,000 RPM's when I rapidly go to full throttle the RPM's drop 1,000-2,000 RPM's then she recovers and the RPM's shoot right back up. I can slowly accelerate with no problem.
I have adjusted the fuel controller every which way and even tested running the boat without the controller. The controller seems to be functioning just fine.
