I found a 2001 YZ426F stator and flywheel for a good price. Will the YZ426F flywheel work on my 2001 WR426F with the original stator? I figured that the lighter weight of the YZ426F flywheel would really add some quick revving to the WR. Also, is the gray-wire mod. completely independent of the YZ cam-timing modification? Does one work without doing the other? Are there any real performance gains by doing only one, or should both be done? Thanks.
