I'd give it a little more time and repeated high speed runs and see if the weave problem returns with introduction of crosswinds or different load or bike configurations. One time isn't enough as the weave is not always present at a certain high speed. That is the problem in trying to recreate the weave after changing one or more things that could affect handling like ride height, preload, sag, load configuration, windshield height, etc. I have run it top speed before and had no weave and then the next time had the weave start at less than top speed. It's baffling. I can say with certainty that my bike will do it sometimes and sometimes it won't.
I can say this with the confidence of trying it on my ST1300 a couple of years ago. I raised the fork tubes (lowered the forks) in the clamps as far as you can without modifying the handlebars which is about 5 mm and found that if anything it made the bike more susceptible to the weave. Lowering the front end or raising the rear end has the effect to reducing rake and trail which sharpens steering inputs fed into the chassis by the rider or unwanted aerodynamic oscillations. I changed the fork height back to stock after a few thousand miles.
