Read the YZ cam mod in the YZ 400 section. It will answer any questions you can imagine. Great mod... :)

I put the 03 YZ450 Exhuast cam in my 02 WR426 about 3 months ago. A very good improvement for the money. The bike doesn't feel a lot faster because the powerband is smoother (Like a CRF450), but it is way easier to ride fast.

Other advantages, less compression braking , easy bumpstarts, and you can kick over the bike while sitting in the seat..

Just do it, you won't be disappointed.

Call www.worldofcycles.com for your cam. Under $100 shipped to your door...

:):D

Is there a difference between the yz cam and hot cams?

Yes, Hot cams claim a mid to upper "improvement" where as the Yz450 cam gives you a much smoother power band with [@#$%&*!] loads of torque down low.

I'm contemplating on doing the auto decomp cam mod in my dual-sported '02 WR426. I am more interested in low end torque than high end HP. I would like the smooth broad powerband though. So for my needs, 95% trails, would the WR450 cam be a better choice?
