I called Kawasaki to see if mine was listed as a CA model. They looked up my VIN and told me. No letter...

Now that is weird, by law they are required to inform in writing on any recalls.
Just the other day there was another thread of someone claiming that they had a transmission recall as well, never heard or saw anything on the trans recall.
Do you have a CA model?
I guess take it in and see what they fill out on the paperwork, maybe they will reference a TSB or a very small group was hit with the recall? That would not answer the fact it does not come up on that website posted earlier in the thread.
