Exhaust Cam on ;04

Is it possible to adjust the exhaust cam on the '04 WR450 or must a YZ cam be dropped in?

For YZ timing you will need a YZ camshaft, sorry :)

Thanks Steve,

I hear it will make a difference & after riding a stock CRF450R I crave MORE! I know the YZ and the CRF are supposed to be head to head.

I'll report any results :)

Yes, it`s a big differance, and you do have to change the cam to the YZ cam, you will not be sorry after riding my buddies bike, that is the next thing I am doing when I check the valves of course.
