I've tried the original tire again, balance beads in and out, no difference. I think it is the bearings allowing the stem to walk a little. My front end already came loose and I've retorqued it twice. Bike has 1300 miles. I think I'll be chasing the front end for as long as it has the loose ball bearings in it.
If it was wheel balance it would be there regardless of decel. At 47 MPH it would shake with a light touch on the bar, like 2 fingers to hold throttle. I've done that, it needs to get loaded by decel to happen. That points me towards wimpy fork tubes/bushings, which it has, or wimpy bearings which it also has.
No decel wobble till it gets to 50 MPH, then it goes nuts. At 40 MPH it isn't there. At 90 MPH no issue. Like I said, my ZZR1200s both did the same thing, same speeds too. big, heavy bikes with relatively thin fork tubes and caged ball bearing steering heads.
