2013 crf 230f

I recently got a 2013 crf 230 and I know someone who has an older model that has an airbox mod with a plastic piece that has been removed and made a noticeable difference so I did the same thing to mine. Now it acts as if it is getting to much air and not enough fuel. should I just increase the amount of fuel its getting or what?

Your bike is most likely running lean. You probably need to do a "power up" mod. It is a low cost mod and makes a nice difference in performance. It's where you change the jets in the carb, unplug the air box like you did, and take the baffle out. These links will show/tell you everything you need to know about it.

What Grogg said!

DO NOT remove the intake restrictor unless you've rejetted the carb! It will create a dangerously lean condition. The restrictor acts like a partial choke, increasing the signal across the metering circuits. Removing it decreases the signal across the metering circuits. You must compensate by increasing the jet sizes.

Alright. Thanks guys. Greatly appreciated.
