the timing wont change, but the yzf flywheel is lighter so all you're doing is lightening the flywheel. the effect this would have is that the bike will rev faster but they will also drop off faster too which may make climbing snotty hills a little more difficult as it will lose momentum faster

Keep in mind that you will have much lower lighting coil current output if you put the YZ flywheel on your WR.
