    2003 GP1300R Air Intake

    Is it worthwhile to replace the stock intake duct and silencer with Riva's flame arrestor?

    Yes! but to make it worth it you need to remove the metal screens in the air box over the throttle bodies.

    In doing so, is it necessary to reschedule the fuel injection? Carbs need to be adjusted after removing the air box. I have removed the cat, installed cat temp sensor "chip" so how does the ECM "know" how the mix is?

    Whats the purpose of these screens? Have you noticed any SOTP difference just by taking those out?

    Many people have run with the riva filter, d-plate, screens removed with no efi adjustments. You will gain rpm from doing this becuase the stock setup restricts air. Any more modifications will require more fuel. The only way to do this is with an efi controller.

    The screens are flame arrestors. I would be surprised to see if anyone has ever removed the screens but kept all the stock plastic air system.

    I gutted the air box and took off the silencer and have had know problems but it does allow a little more air flow. Which with my setup helped a little bit. Sorry I have no factual numbers to back this mod up but there was an improvement.
