Trying to find piston and rings .20 over for this bike. Can come up with piston, but no rings. Wiseco says 3 models took the same piston and rings according to their records, though they do not have any more. Kawasaki cannot advise, nor can I get specs for the KE or other models of that year. What would anyone suggest should no specific rings are available? Any possible way to get another set of rings for another application? Any suggestion on NOS for this vintage?? Or, how about any other suggestions? Would be appreciated. Brad
