If they're original with 40-odd on the clock, they're likely shot, and will give you the symptoms you're noticing.
Go for tapered rollers, much superior to ball bearings.
While you're at it, a little trick I did on mine after noticing that the bottom surface of the lower bearing is essentially open to the elements was to trim a rubber diaphram to fit over the bearing cap, then packed it with grease to keep road gunk outta there.

I'd give the neck bearings a good looksee.

I could not agree more. If the problem continues let the forum know....if it goes away tell us as well...

As a mechanic I've learned to ask this question... Did this problem start after you got it back from servicing? If so, it was NOT there before the work done. You need to check their work. Something not adjusted right, something loose? (My first impression was low tire pressure) Let us know...
Entirely cool way to look at the issue.
Though the original post didn't specify, the implication is that the condition existed before the shop got ahold of it - hence the bushings and tire swap, etc...
But oh yeah, a loose swingarm bolt will definitely cause that kind of feeling at those kind of speeds...
Double checking shop-performed servicing is *always* a good idea.
Still, at "42xxx", I'd expect those neck bearings to fall apart as soon as daylight hits 'em...

1) Mis-matched (diff brand or compound) tires can sometimes cause instability that might not be noticeable at low speeds, but will make you very aware of it at higher speeds.
2) Worn or damaged cush damper, which is located directly behind the sprocket hub on the rear wheel.
3) Worn front and/or rear wheel bearings or spacers.
4) Ribbed treaded (straight grooved pattern) front tires are notorious for catching those little rain grooves in the freeways here in So Calif, and will certainly make the bike feel "squirrely" at speed.
Have you had a chance to take her up to the speed where she feels unstable on a plain old asphalt or concrete road w/out rain grooves yet?
That would at least rule out the ribbed tread pattern issue.
