Seems that there is a resonant point along the power curve at about 3900 rpm and only 5th gear, where the chain starts displaying severe vibration horizontally *and* vertically... net result is that the chain loosens prematurely, and if it gets loose enough, it hits the tire (mainly because the tire- chain clearance is only a quarter inch or so... Of course, Kawasaki is stumped... even there regional rep doesn't know what to do about this one. The problem is generic - at least four other CRS's have the same problem... All suggestions *very gratefully* appreciated..... Thanks, Mike Sajor BTL Whippany NJ ...harpo!zeppo!mes
