Smog block off plates YAMAHA MT09 / TRACER / XSR / NIKEN 900


Smog block-off plates (also known as PAIR valve removal kit) specific for many YAMAHA models. You will find the motorcycles compatibility list below.

Sold as a complete kit :

  • 2 block off plates (to install in place of the PAIR valve plates on the cylinder head) 
  • rubber caps for the airbox


Let's face it, if you're a biker, you'll never be the Nobel Prize winner for ecology (at least, as long as there is an engine running on your 2 wheelers). Without denigrating the beautiful cause that is the defense of the environment, we’ll all agree that the PAIR System is not really an ally for bikers in general, and even less for track riders.

Whether it is to prepare or adjust a setting on your motorcycle on a power bench, or to reduce or even eliminate the detonations coming out of your exhaust when downshifting, you may have to remove the original smog system of your motorcycle.


But suppressing your PAIR system will also allow you to :

  • Take much less space in the engine compartment and allow a significant reduction of your motorcycle’s weight
  • Get a more accurate air/fuel ratio (e.g. useful when making adjustments on a dynometer or power bench via a Power Commander)
  • Get more power and a smoother running engine at lower speeds (depending on the motorcycle's model)

In short, the advantages of removing the PAIR system on your machine are numerous, as you can see. 


Concerning the installation of these plates :

Until a few years ago, you would have had to build up your own covers with the means at hand in order to achieve this, a process that could clearly seem risky. But these dark times are over, and now there is nothing easier to do thanks to this pair of specific plates ! 

Indeed, you just have to install these two covers on the holes of the cylinder head cover (after removing the old valve caps from it), plug the rubber cap on the air box, and it's done! 

It's as simple as that. That's why this complete kit, specific to the motorcycle models mentioned above, is sold ready-to-install and is composed of :

  • A pair of aluminum block-off covers
  • A pair of rubber caps


As simple as it is effective, this kit will delight most bikers for its usefulness as well as for its affordable price!
