2004 WR 450! Would like to do some mods??

I have a 04 WR450, with a CRD powerpipe, and twin Air filter. Its time for more snap. Just Want to know what free mods to do, and weather JD jetting is a wise option before or after what particular mods? Any advice is appreciated thanx.

:p:cheers:

Aussie free mods are just opening up the side of the airbox for the '04.

If you want more snap, there is a few things you can do.

You can block off the ACV on the side of the carby, when jetted perfect it will have a fair bit better throttle response.

You can lockwire the accelerator pump arm to the actuator, same thing, better response.

A YZ cam (or hotcams) work a treat on the WR's too.

search for the "grey wire, snorkel removal and throttle stop mods". I personally couldn't tell much difference as the bike out performs me anyway and the last two were already done before i bought it from the dealer.

Pretty sure there's a sticky on it.......
