Answer
Bruce,


sounds like a balancer problem.

Check the balancer idler lever (Kawasaki part no. 13168-1436)
and the idler shaft spring (Kawasaki part no. 92144-1860)

These balancer parts keep tension on the balancer chain.
I suspect the idler lever may be broken.
Sometimes the weld lets go and it falls apart.
