Just found this site. I have a 1981 GPZ1100 with about 16000 original miles. However, also, had value job done (at Kawasaki recommendation and expense) New tires. Chain not to bad. The known issues are:I need to find a value cover gasket, install a battery, and un-stick a frozen front caliper. So. just for the heck of it--- was interesting in knowing the approximate value of it.
