The only thing I touched was the tie rods
Did you touch the tie rods; spin any wheel, disc, or hub by hand, or drive the rear wheel with the engine; or do
anything in your wheel alignment process
with the ignition on? :dontknow: . What about doing
anything with the engine running &/or it in gear? :dontknow:
Have you taken it on that (careful & gentle) ryde of, saaay, 100 yds or so yet? If not, then do so now. If so, then please tell us what happened?? :dontknow:
Failing all or any of that resolving your issues, then as mentioned here:
.......
If that doesn't resolve your problem, then you've probably disturbed, disconnected, or broken one or more of the speed sensors or the notched index ring that they use to determine tire rotation speed found on each of the rims/hubs.... it could even be just that you've mis-placed or incorrectly installed any of the spacer washers used to keep the sensor at the correct 'flying height' above the index ring! These sort of problems can be a little harder to diagnose &/or remedy, but they still are usually resolved just by fixing/replacing the offending component & then ryding it for a bit, so they aren't really catastrophic - just a pain in the butt until you can get them sorted & get back to ryding!

....
So you'll probably need to carefully check the speed sensors to make sure they're clean; located properly; spacers in the correct position; and that their wiring is patent & properly connected. You should also check those notched index rings on each wheel to make sure that they aren't bent, damaged, misplaced, or even just clogged with mud or grease or whatever. :lecturef_smilie:
And if you do or have done any or all of that, then please, come back here & tell us what you found, did, or what happened. :thumbup:
Over to you! :cheers:
