air box mods?

Recommended Posts

has anyone done any airbox mods to there yz250f? if so have you changed the jetting? ive done a few cuts near the rear of the box and i plan to lift the seat so it sucks even more air. i changed my main from a 182 to a 185 it seams to get more power.

just cut the rear wall down flush to the fender and then bend the seat tangs so it sits up off of the fender. It's good for another jet size. Swapping the filter cage for a screenless one is also good for more airflow.
