Thread: Flame Arrestor

  1. #1

    Flame Arrestor

    Need help installing the flame arrestor for my 1300r. From where I've looked, there arent any instructions on the web, but some posts say that it's easily installed. So far it seems to be a pain in the a**. Do i need to take off the whole exhaust tube, or is there an easier way of getting to it? Also, if/when I get to it, do I just slap it onto the end of the throttle body and discard the tubing & intake silencer assembly? Or do I need to keep the intake silencer and tubing?
    Thanks,
    - PHISH

    GP1300R Race Filter Installation

    Welcome PHISH !!!

    I assume you are installing the Race Filter.

    Yes you do have to remove the stinger pipe.

    I will run it down for you right quick.

    Remove the two top pipe mounts at the head
    Remove the lower pipe mount rear of engine
    Loosen the top black rubber boot clamps and slide it forward
    Loosen the clamps on the grey exhaust sleeve underneath the black boot
    Loosen the clamp on the black boot rear of the pipe.
    Loosen the clamp and remove the water line from the top rear of the pipe
    Unplug the Cat temp sensor wiring plug on the side of the CDI box
    Unplug the Water temp sensor wiring plug on the side of the CDI box
    From the left side of the boat, grab the pipe at the top rear and pull/pivot the pipe towards you.
    The front should come out first and lift up and out of the way
    To remove the factory air box, remove several phillips head screws (13) from the outer edge of the box.
    Now you can remove the outer half of the box
    At this time remove as much of the restrictive air intake toward the front as you want or that you can get to.
    Loosen the (3) clamps that hold the inner box to the throttle bodies.
    Locate and remove the (2) bolts attached to brackets on either end of the remaining portion.
    Be sure to clip tie-straps holding wires and hoses to the air box and before removal. Also an 03 boats, be sure and remove the air temp sensor from the box before removal.
    Remove the remaining portion of the box.
    Use the clamps that were on the factory boots to attach the Filter to the throttle bodies
    Take a moment to re-secure any wires or hoses that may have been removed
    Reverse the procedure to re-install the pipe.
    Also ALWAYS use loctite and a torque wrench on re-assembly, and refer to your manual for specs and exploded views.
    Also dont forget to re-attach that pesky bearing grease bracket and zerk to the top of the pipe mount

    Tech Tip: Use soapy water in a spray bottle or Windex to lubricate the rubber boots to ease assembly.

    Hope I didnt forget anything, and good luck!

    OK, everything is all good now, although one of the straps holding the rubber tubing on was giving me hell. I got pissed off and whipped out the Dremel...now its off. Anyway, set the EFI to 3 5 1 8, will check out how it runs next weekend...too crappy out today

    UPDATE INFORMATION

    I just cracked open a 06 GPR the other night and the clamps that hold the air box-to-throttle bodies were almost impossible to get to. The allen heads had to be loosened from the bottom. It was easier to remove the throttle body assembly from the engine side rubber boots. Then I simply rotated the whole assembly and unscrewed the clamps. I was then able to remove the entire box without opening it up. That was much easier than removing all those screws that hold the two pieces of the air box together.

    Yes, My '06 was the same way. I had a hard time until I figured out to just go ahead and pull the throttle bodies loose so I could get at the clamps.
