i was experiencing the same issues, then moved the tubes down in the tripple trees a few mm and the handling improved greatly

I am using a mx51 90 in the front
I will try different positions on the forks, thanks all

Coming off a YZ, keep in mind you are also carrying a little more weight on the the front end of the bike now in comparison, which will need to be compensated for.

I had Smart Performance shuffle the shims on it and it's like a different bike now.
I just wish I had done it much sooner.

I also have a 2006 WR which is a little more stable. I suspect that the softness of the front end is partly to blame on both bikes. I'd bet a good revalve would cure all this but I'm selling both bikes and may eventually get another brand.

Set your race sag to 106 and change your fork oil to 7wt or 10wt and set level of oil to 110 mm below top of fork tube with springs out and tubes collapsed. Adjust compression and rebound for thicker oil.
After that, then do like a lot of others did - spend hundreds of dollars on suspension mods, get frustrated and finally give up on making the WR suspension work and either put YZ suspension on it or just sell it and move on to something that can be made to work half decent.

It was fixed by installing Race tec gold valves. They use shims instead of a spring.

Hang on to your '04 YZ.
I rode the 2012, 2009 and 2006 WR450's back to back yesterday in some hilly, deep sand tracks with a lot of jumps. The '09 had stock suspension. The '06 had Race tech[color=#282828] valving and slightly heavier fork springs (.47), and the 2012 was stock. I am 165 lbs, b-level rider. Both the '09 and '06 are mine, set up at 105mm sag. The '2012 was at stock settings.
My impression of all three:
2009: stock suspension is rediculously inadequate. For my style of riding, it is a little twitchy even at 106 mm of race sag, with forks set flush with top of clamp and with a steering damper. You have to be agressive and 100% focused in the turns all the time. My guess is that the alum. framed WR's have a steeper rake, at least that is the way it feels to me. Depending on your riding style, this may be good or not so good.
2012: stock suspension is purely phenominal!!! I jumped off a 2-foot ledge at high speed,[/color][color=#282828] and it was if I never left the ground. Very supportive but ultra smooth action! Handling is a little better than the '09 simply because of the suspension but still feels a little less stable than my '06 WR. The sag was obviously wrong for my weight. It was difficult to wheelie.[/color]
[color=#282828]2006: Still my favorite right now for two reasons - very stable cornering and stable when on the back wheel. The geometry of the chasis makes it easy to go fast. . I am getting very close to finding the proper valving combo for this bike with Race Tech, although it will never be as good as the SSS suspension on the '12 WR.[/color]

This is similar advice to what has already been given
