Hear the rumor that the cam chain pitch changed so that one should be careful which YZ-cam he sticks into his WR.
With what model year did WR resp. YZ use a different cam chain pitch?
My plan is to buy a '06 YZ450F cam and put it into my '12 WR450F.
edit: case closed. the cam chain is identical between '12 WR450F and '06 YZ450F, hence the sprockets must be interchangable.
