Honda CRF250X & CRF450X Airbox Mod

http://www.rockymountainatvmc.com/t/2... If you own a Honda CRF 250X or a Honda CRF450X you know that your stock airbox restricts airflow greatly. One way to get around that limited airflow is you can complete an airbox modification and open up the airflow to your engine for significant power gains. Jay Clark walks you through the proper way to do this modification and open up the airflow to your motorcycle. We also provide you with some jetting recommendations to help with re-jetting your bike after you complete the airbox cutout. This simple mod for your Honda CRF250X or 450X is one of the most inexpensive ways to increase the power of your motorcycle.
