    How To: DIY Ribbon Delete for Yamaha FX Series (MR-1)

    I wasn't able to find a good write up so I took it upon myself to do a quick tutorial on this mod. It is fairly straight forward so I will not bore you with every tiny detail. I haven't been able to test the difference on the water but the throttle is definitely snappier and responds quicker. Others have reported a minor improvement in throttle response as well as a couple of reports of slightly increased RPM's and mid-range power.

    1. Remove air box cover and air filter assembly.

    2. Remove the (2) silver, shouldered 10mm/Allen bolts holding each pair of flame arrestors in place. One assembly has been removed in the picture below. It is wise to cover your exposed throttle bodies to keep debris from entering the engine.




    3. Carefully wiggle (while pulling upward) and remove both pairs of restrictors. Lay on work bench for next steps.




    4. Using a 3/16" drill-bit, slowly drill out the existing rivet heads (drill side without washer) and separate each pair, removing and disposing of the flame arrestor disc.




    5. Thoroughly clean and reassemble each pair (paying attention to original orientation) using new rivets or screws. The parts have assembly tabs to make orientation easy.




    6. Reinstall each assembly using the original 10mm bolts. Reinstall air filter and air box assembly.



    Thanks,
    CCW

    already did that, it will improve the bottom end and give you a crisp throttle response, maybe .5 mile.
    these rivets were a bitch to drill .

    Yes, because they want to spin. I just held the protruding side with small needle nose and it was cake. Tip: do not put much pressure on the drill bit. Let the weight of a sharp bit do the work or the rivet wants to spin more.
