The low end feels weaker, but that may be due to the very strong run up into the mid range. I can ride a long wheely more confidently (I suck at wheelies) on the WR due to the smoother transition. I can see where in limited traction situations the WR timing has an advantage, but other than that I see no real reason not to try it.
Hope this helps.

You won't miss a thing and on those huge gnarly hill climbs......just open the throttle and lean forward........then get ready to shift up as you head up the hill

The best way to recover the low rpm response is to add a Power Now/James Now... from personal experience this device results in a YZ timed 426 being as responsive (if not more responsive) as the WR timed version.
As per other posts a slight rejet may be required with the timing change (mine needed to go leaner)
In my opinion YZ timing in concert with James Now is the best combination for this motor, its tractable, controllable and responsive.

This is so true!!!
On my WR426 I decided to time the bike to YZ spec just to see what all the talk was about.. Im my personal opinion I feel that the YZ spec makes the bike "faster" up top. It really makes the motor come alive in the upper revs. What you lose it throttle control.. I feel that in tight sections the WR timing is better. The WR426 tends to be a handfull in tight sections as it is stock, YZ timing your bike will make it worse and your bike will be more prone to stall. The best word to decribe the YZ spec is "hollow".
I'm one of the only members here that thinks WR timing is better.. I can ride though,tight rocky sections with more confidence and better throttle control with stock timing..
If you're looking to make your bike faster, someone mentioned a YZ cam with auto-decompression... This would be the way to go.. The auto-decompression is one of the best things about the new 450's...

In the last enduro (only) I rode, I was having no problem, lofting the front wheel or making tight turns directly into steeper uphills. At 250lbs out of the shower this setup had no problem pulling me up anything I can think to ride up. I would agree that she does get a bit touchier about stalling though. but with the immense power gain at higher revs I think its a wash.

You mountain folks need to come down here to sea level and see what your bike can really do.
