'12 - '14 ?

 

The rearward facing cylinder YZ bikes have the new TC and offsets, whatever year those are.

 

The WR upper fork tubes are 54mm.  The new YZ upper fork tubes are 52mm.  You need to bore out the upper clamp 2mm.  I used a simple boring bar on a milling machine.  It took an hour.

Yes, on '12 to '14 WRs.  Not sure about previous (non SSS) years.  Mine is a 2012.

 

If I was going to the work of upgrading TCs on a pre 2012, I'd upgrade the forks to SSS as well.

I do know that the YZ SSS and the WR SSS forks have substantially different flex characteristics; the YZ being much stiffer.

All the WR fork part numbers except the lower fork leg and a few damping components are the same between the '12+ WR and the pre rear cylinder YZs.  Not sure about the rear cylinder YZs, but the upper diameter of the fork tubes is smaller on them.
