Late to this thread but I am experiencing something like the weave I think you are describing, but I would call it a wobble because it oscillates slowly back and forth at high speed. Had the problem on worn tires so just put on a set of W rated Bridgestones. Bike feels a little jittery at 100, but as I approach 130 it begins to "wobble". Getting off the throttle does not elimate it until I reduce speed back to 100. Wondering if the forks need checking (resealed last year) or if the wheel is out of round. Thanks for any help.
