Do a search on this forum as well as the YZ450 forum and you'll get all the info you need.
I just did mine on my 07, there's some info in this thread.
Just double, triple, quadruple check your timing before putting it back together.

Set the engine to TDC.
At this point, LOOK at the left and right cam - they are pointing to the outside of the engine with their lobes, you can count links if you want but when you look at the dot on each cam at the outside point - it WILL BE LEVEL with the top of the head - that's really all you need to know - just put them back the same way and verify the engine is still at TDC.
Yes you can also change to YZ timing - do a search - it's all been documented - might even be in the technical articles section......

It looks like someone timed that YZ already, there are 13pins between the 12:00 marks.
That said the timing does look a little funky.
But since your replacing your cam chain anyways just pull them and make sure you line them up right when you put it all back together.

there should be 12 pins on the 426 for yz timing and 13 for wr. yes it runs good
My bad, on the 450 it's 13 YZ and 14 WR.
