50 mph Headshake

[TahoeBound]

I just replaced the front forks so obviously the likely culprit. Plus, I'm having plenty of problems trying to dial the Race Techs in. Wondering if you use compression, rebound dampening (or both) to get the headshake under control. Strangely, there is no problem at other speeds, fast or slow.

The front Storm has ~1/2 its life left, so I wouldn't think that's contributing.

Bet it's the tire. Different forks changed the sensitivity of the bike to the tire wear.

Change the tire. And while you're messing with it, back compression out all the way (20 clicks or so). Adjust rebound to your liking, then (and only then) add compression damping.

Provided that the forks are put together correctly (same actual internal preload on the springs, same clicker settings and ride height), your head shake is almost certainly the tire.
