dirt bike K&N filters

does anybody run a k&n air filter in there dirt bike. i here that they bring in alot more dirt since they flow more air in to the motor. what can you say about them.

Ive ran open element and k&n filters and they work great! Make sure u rejet what ever you do. You will get way too much air. Once you rejet... you will get sooo much more power!

depends on what type of bike you have.

if its a high rev four stroke like a 450r
rejet and get the k&n if your airbox is clean u wont get dirt in your motor.

i dont know about two strokes..
