Has anyone had any experience with head shake? Was on the 99 today with my 97 ZX9R, had just shed the cages, and was opening her up when, at exactly 150KPH (straight, mildly accelerating, not on a curve or braking) some pretty serious front end shaking began. Scaaaarrrry. Clamp and steering seem good....wondering if it's just the rim. Tight as todd at lower speeds, with nary a suggestion that it's lurking at the higher.
Any suggestions appreciated, except for Kawi=junk.
