I am sure I mised something. If you want a bike that runs like a YZ, buy a YZ.

all the free mods, hotcam's or YZ cams, dump your estart, battery, and lights, side stand, and full exhaust, and it will certainly be more "YZ'ish" (not to be confused with "it will work as good as a YZ") while keeping what *most* consider the good stuff from the WR for woods riding which is the wide ratio tranny, heavier flywheel, 18" rear.

Anything more then that and I would suggest selling the WR to pick up a YZ.

For the record, *I* consider the magic button and side stand as must have for my own use...lol
