I've got an interesting problem with a Kawasaki CSR 750 (1982)...
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,

In reference to the Kawasaki chain drive problems I had on my CSR 750...
First, thanks to all who called, wrote, mail(1)ed etc....
The problem turned out to be a combination of two things:
(1), the alignment marks stamped into the arms were *not* true with
each other (off by about 1/32 in or so) (and this was true of 3 bikes
examined) and,
(2), Unless a tightening procedure for the rear axle bolt is followed
as specified in the service (but *not* owners) manual, the bolt side can
force the entire wheel slightly to the left (as facing front), thereby
causing the rear sprocket to lie out of plane with the front...
After following the proper procedure, everything worked fine, and i am
enjoying riding without having to worry about where exactly on the power
curve I find myself! (aside from normal concerns)
Thanks again to all who responded...gee whiz, ain't news great!

My old Kawasaki A7R was almost a whole mark off from true. I also had a Honda 450 that was almost as bad. The only way I ever set my axle is with an elastic string in a large loop so that it can go around both tires about 4 inches off the ground. Put the bike on the centerstand and turn the handlebars until the gap between the string and the read of the front tire is the same on both sides. I then put a spacer (1/2 styrafoam) on each side. Then I adjust the rear axle so that the gap is the same on both sides at the front of the rear tire. It may be a little tedious, but it does make a difference.
