    Flame arrestor question

    Has anyone installed or heard of anyone using the mega filter or the power plenum filter that go on the end of the factory gp1200r air box? I am rejetting my carbs and wanna either buy some F/A or use my factory air box with the power plenum or mega filter? Any ideas or comments would be helpful. Thanks in advance.

    Yes, but you can probably get a 4inch k&n for much cheaper. You just have to gut the airbox and take out the metal screen that's in there. I prefer this setup over the 3 individual arresters because the filter/arrester sits forward and farther away then any water that might be splaying around the mid wall while I'm riding in the surf. Some are going to tell you to get the riva/r&d setup for more power but let's be real here, unless you tested both setups Back-to-back I doubt you will notice a difference unless you are chasing numbers. Simply put all the restriction comes from that ridiculous intake tubing they have in there and the screen.

    So if i just get a k&n filter and stick on the end it wont be restrictive as the factory? I do a lot of riding in the gulf and want something thats not restrictive but will stop water from getting in.

    Yup and a hose clamp, just make sure you gut the box as well. The stock intake tubing is long and twisty with chambers, very restrictive. You can also trim the closed vent on the one side as well for a little more air into the hull.

    Which vent are you referring to and where is it located?
