jus wondering if there are any free mods for the 03 wr450f, i noticed the airbox is a little choked and there is a big breather behind the bashplate any help or pictures would be awesome.

Disconnect the gray wire from cdi, uncork the pipe, shorten throttle stop, and pull the snorkel out of the airbox. Re-jet a bit richer after the pipe/airbox mods because she'll be breathing better.
