Grey wire WR450 photo is in here
Changing the WR450 to YZ timing has not been completely cleared up yet. The issue is the autodecomp on the exhaust cam. On the 426 is was just a matter of changing the exhaust cam position by on sprocket tooth and you have YZ timing. With the WR450 cam doing this one tooth trick will also change the timing of the autodecomp. Some folks guess the WR450 won't be able to electric start with the exhaust cam timing changed by one tooth.
Maybe someone should ask how many of the sheared woodruff keys have been on WR450's with YZ timing on the exhaust cams.

Can we do the wr/yz timing change or do we need a new cam??
