Guaranteed Weight Loss With The Latest California Diet!

 

If you live in California your CRF250X and CRF450X come nicely equipped with a full pound of emissions equipment. This pound of equipment is one of the most important pounds that make up this great off-road racer. Why, you ask? Because this "smog pump" is what makes it possible for these bikes to receive the coveted California Green Sticker. Without a green sticker, legal riding areas would be limited to certain months of the year or not at all. With a green sticker you can ride in most legal areas year round.

 

Note: Removing emissions equipment is for close course purposes or where there are no green sticker requirements.

 

The Applied Racing Emission Block Off Kit has thee components. A vent plug, smog pump block off cap, and a brass bolt. Installation is very simple. First remove the smog pump and hoses. Once they are removed, you can install the kit. Here's a more detailed installation procedure.

Installation

4. Remove the smog pump by removing the hanger bolt. Remove the pump and hoses. That's it.

 

The Podium

  • Well designed and manufactured
  • Eliminates nearly a pound of emissions equipment
  • Prevents hot oil-rich air from entering the carburetor
  • Reduces clutter around the right side of the frame and motor as well as the air box
  • Instructions are excellent, installation is quick and easy

Conclusion
Many are probably wondering if removing the smog pump will have an added benefit of increasing performance of the motor. Unfortunately, we did not detect any increase in performance in our CRF450X after removal. It does however reduce clutter around the right side of the motor as well as around the air box.

Lastly, as I was completing the install, Stevie Ray Vaughn's "Tax Man" was playing on the shop stereo. I couldn't help but wish Applied Racing made something to eliminate taxes too.

The Pits

  • It doesn't appear the smog pump hurts performance so removing it doesn't add performance
  • While it eliminates the smog equipment it does nothing to eliminate taxes
