stator head light 18" rear wheel wide ratio tranny cam timing. pretty minor. it doesnt take much to yz a wr. i dig the 18" wheel hook up. lots of torq off the bottom. the wr is a wheelie machine!

The only change I would like on my yz is the 18" wheel. Now that falls here, a stator and light would be nice too! The lighting would also add some flywheel weight. Hmmmmmm.............................
