On my 04 WR450 I figured the extra 50cc will be enough extra grunt not to need the gearing change.
You may want to keep in mind that the primary is different between the two, this difference is worth about 3 teeth out back. That is, a WR 450 w/ 14/52 would be equivalent to a WR 426 w/ 14/49. The internal ratios are the same.
Hope this helps.

I'm going to run a 14-52 combo, It will widen 1-2-3 compared to 13-50 gearing, but will tighten up 3-4-5, compared to stock 14-50, which I find will lug the engine down in really deep wet loam and muskeg.
I found that the 13-50 gearing was great for mx too.
Just used 3-4 gears.
I think the 14-52 combo will be the best comprmise for throttle response, top end speed, and mx use.
Also I found the 14-50 gearing too tall to pull 5th gear much over 6000 rpm in 5th.
She was really lugging down in 5th gear in 8"of snow, especially triing to overcome the heft and tire hight of the studded trelli's I run in winter.
