Yes, cut the grey wire, this will change the timing curve in favor of increased performance.
The bogging is a jetting issue. There are many guys on this forum currently trying to figure out the perfect WR450 jetting. The carb. on the Wr450 is completely different from my Wr426, so, I cannot really help you. I suggest you do a search on jetting or look at the jetting q's and you will get a feel for what you should do. There have also been some recent posts on WR450 jetting. From the work that others have already done, you should be able to get close.

When I picked up my bike, Ray (the guy at Yamaha) had already "uncorked" it, ground the throttle stop down, removed the air baffle T-looking thingy, and done something to the grey wire (which he explained was the rev limiter).
I had him put on a Pro Moto billet silencer because of my line of work. (I was in Georgia when he put the bike together) He liked it so much no bikes go out of his shop without one now.
That and jetting should rear the beautiful beasts head.
