WR cams are designed for low end torque and YZ cams for high RPM power.

Having said that, cams are the biggest thing you can do. Make sure you're jetted correctly and all the free mods are done as well.
Lighter flywheel, compression bump, pull the electric starter, lots of things like that which make the WR a WR. And for most of us, that's a good thing. But the only way to be a YZ, is to buy a YZ.

I am interested in the answer as well I am considering the same thing as I race a 09 WR450 in HS and GNCC with a few enduros thrown in, I prefer the softer hit of the WR set up but would love to lose the miles of wiring harness, battery, starter ect.
Is the YZ magneto cover a direct swap to the WR case?
