    2012 FX Series

    Thought I would start a “project” thread on the new 2012 FX series. Hoping that everyone will contribute and share ideas they come up with for the new model.

    I’ll start off by adding the first thing I did which was move forward my GPS mount setup onto the new model.







    Parts list:

    RAM Mount Balls for the storage lid (I bought 3 of these, can get away with just 1 if you only want 1)
    http://www.gpscity.com/ram-mount-fem...am-b-348u.html
    You will need to pickup the stainless screws and washers at your local hardware store.

    Buy this arm as it gives you much more flexibility in adjusting the angles to have the GPS face you. Don't waste your money on the non adjusting arms.

    Cradle for the GPS 76, for those who have the GPS 76
    RAM Mount RAM-HOL-GA14U Plastic Garmin GPSMAP 76Cx 76CSx 96 96C Series Unit Cradle
    http://www.gpscity.com/ram-mount-gar...hol-ga14u.html

    Ball mount you will need to get GPS Cradle attached to arm:
    RAM Mount RAM-B-238U Aluminum Diamond mini Plate with 1 inch Ball
    http://www.gpscity.com/ram-mount-dia...am-b-238u.html

    Strongly suggest getting another lid so that when you’re done riding at the end of the day you can simply unscrew the lid and swap back to the normal lid. That way you don't have to keep adjusting your ram-mounts. Just unscrew it and toss it into the back seat. Then on the next time out just screw it back on the storage compartment and have everything ready to go.


    Also the Gopro Mounts for this setup:
    Here is the RAM-mount adapter you will need for you GoPro:

    To get the GoPro setup to record above the hood and in the middle of the ski, I use one of these connecting ball mounts to put two arms together to get the right height and shooting angle:

    Next contribution is upgrading the stock air filter to an aftermarket filter. There are other members of the forum who have done similar setups, however what makes this different is the mount setup.

    Started out with a 3” aluminum 90 degree pipe that I bought off Ebay:

    Aluminum Intercooler Intake pipe 3" OD 90 deg Elbow
    http://www.ebay.com/itm/Aluminum-Int...6be8be&vxp=mtr


    Next cut off approximately 4 inches of the pipe and mocked it up near its final location:




    For the mount I cut a 10” piece of aluminum angle stock to mount the intake pipe to using T-Bolt clamp.


    Removed the side panel and drilled holes in the angle stock to match the bolt pattern of the side panel. It took a couple times of trying to get the holes aligned correctly and to get the correct angle and location of the mount for the filter pipe. After getting the side holes drilled I drilled a hole in the top of the mount to later attach the Tbolt clamp:




    Reinstalled the side panel and added rubber washers between the intake mount and the hull:




    Installed the filter and Tbolt clamp:




    Created a washer stack to help with vibration (all parts from Ace Hardware):




    Bolted it all up and tightened everything down:




    That’s it. The mount system is very secure and keeps the filter off of the gas tank and from flopping around. Total cost around $40 (already had the air filter).

    Free Flow Exhaust:


    Cut up some left over exhaust piping I had from my 2009 ski and finished up the free flow exhaust using the old piping and a 130 degree elbow along with a 90 degree pipe. Worked out good so that the weight of the exhaust is supported, no stress on the outlet flange

    After riding 23 hrs with the drone from the Free Flow exhaust, I got tired of it and went back to a mod I did on my 2009 ski, which was installing a T Pipe in line with the free flow exhaust kit and re-attaching factory side branch resonator.

    Side branch resonators essentially work the same as blowing air over a coke bottle, the air passing over the opening makes a noise. You can adjust the pitch of the noise by adjusting the volume of the coke bottle. Bigger bottles make different noises than smaller bottles. Essentially this is how a side branch resonator works. You tune the noise being made from air blowing over it to cancel out unwanted noise frequencies such as exhaust drone.

    Here are some explanations and practical applications:

    How stuff works, resonator:
    http://auto.howstuffworks.com/muffler4.htm

    Scientific review of exhaust applications. See page 41 for side branch resonators:
    http://www.enoisecontrol.com/related...rrier_wall.pdf
    Tuned resonators can be used to attenuate specific frequencies in the exhaust spectrum. There are a lot of different resonator designs, but the simplest and easiest to understand is the side branch resonator, sometimes called the 1/4 wave resonator. A side branch resonator is nothing more than a dead-end section of pipe connected to the main exhaust pipe.

    Tuning a side branch resonator to eliminate drone in a 370z:
    http://www.the370z.com/intake-exhaus...rks-great.html
    To get rid of drone (pipe resonance), you need to cancel out those specific pipe resonant frequencies. To do this without using a chambered muffler you can use whats called a Side Branch Resonator. The side branch resonator is a pipe, around the same size as the exhaust pipe, which T's off the OEM pipe between the rearmost mufflers and the exhaust tips. The length of the side branch pipes matters a LOT! To cancel out the frequencies you need to have them reflect back at a quarter wavelength from the side pipes that T off the main pipe. After re-doing my math and using some Audacity frequency analysis, I figured out that they had to be 27-28" to work at the RPM I wanted. Longer pipes tune out frequencies lower in the RPM range. Shorter pipes (increasingly less effective) hit the higher rpms. I had the mechanic fix the pipes to 28" and VOILA, absolutely zero drone from 2200rpms to 2800rpms. At 2000rpms there is a slight rumble in the cabin, but no drone.

    Here is how I applied the setup to the 2012:


    Side branch concept (T pipe is the same I used on my 2009):




    No restrictions in the T pipe:




    Everything installed:





    Results are a pretty straight forward, a free flow exhaust that does not drone. Exhaust has a good sound and is less restrictive than the full factory exhaust.

    where did you get the t-pipe from?

    I used Matt Boesch (http://www.boeschbuilt.com/) to make the pipe. He does awesome work and is reasonable on his pricing. Check out some of his examples off his website.

    I had him fabricate an 3.5 inch aluminum pipe 8 inches long with a T off the pipe to attach the resonator to. The T is 2 inches in diameter x 2 inches long. The pipe came out flawless with zero restrictions.

    Here's an idea I came up with to make good use out of that wet storage compartment in the back.

    I never liked the idea of the 2012 model having the fire extinguisher up front (was in the back on the previous model FX SHO). Prefer to use the front storage space for life jackets, coolers, etc. So I put this together.


    Yamaha water tight fire extinguisher holder (part EW2-U5920-00) - $20:




    Filled the new holder with all the necessities asked for during a safety inspection (Fire Extinguisher, Whistle, Registration), that way if inspected its all there in the same spot:




    Picked up some foam padding that matched the diameter of the fire extinguisher.




    The foam padding provides a snug fit for the fire extinguisher in the rear storage compartment, also protects the paint against vibration and prevents it all from flopping around:
