I put a YZ ex cam in my 02 and I like the way it smoothed out the power band. Here is a chart showing the difference and the instructions in case you decide to do the install.
Another cheap but effective mod is the BK mod. Click on this link, tech articles, BK mod. It allows you to shorten/adjust the spray time of the accelerator pump. A lot of other great advice on the site too.

If you have off idle problems, specifically a bog when cracking the throttle. I would suggest researching the O-ring mod rather than the BK mod. I too have an 01 WR 426, and I have recently removed the BK mod in favor of the O-ring.
Hmm, what is this O-ring mod you speak of?
