Just buy a YZ450 exhaust cam. I have a buddy that is buying a YFZ450 exhaust cam for his YZ450 to make it half way between a WR and YZ timed!
Do the cam mod (move it 1 tooth on the cam timing)
I have a few friends that moved to the YZ cam and it hurt starting ability, not to mention was not as big of a gain as simply changing the timing. Not trying to start anything, but have first hand experiance on this one. We lined up 2 quads (YZ camed) vs (YZ timed) - you wouldn't think it would be different, but it is - YZ timed pulled much harder on the top and maintained ease of starting. YZ camed had a little more bottom and fell off on the top + became finicky to start.
