Also after doing the normal mods on the WR, does it come close to the HP of the yz..

A stock WR makes 37.0 HP @ 8610 RPM and 23.79 ft-lbs @ 7610 RPM
I have seen dyno runs in the mags of 49 - 50 for the YZ and the WR comes in 45 - 46.
Testing was done at 60.0 F 33% humidity and 34.6 inHg As for a YZ I don't know how much Horse Power they make but I do believe it is somewhere around 50 HP. I also know that if you do all the free mods on the WR it does come in somewhere around 45 HP. Add a YZ cam, a GYTR pipe, and get it jetted right and you should come in right around your 50 HP mark with the WR
