Actually, I think you are talking about the CDI trigger. I lost my CDI trigger on the start line at a race in May. I was so irritated, I just purchased a new stator plate complete with both the stator coil and CDI trigger from kawasaki. However, as I understand, Ricky Stator can either provide a new trigger or rewind your old trigger. Here is the web page:
http://www.rickystator.com/I didn't have my trigger fixed as I didn't want to risk having the thing break again. We are often 30-40 miles from the next living person, so would have to tow a bike a long way to get to the van. If I remember, a stock stator plate is over $300.00, so not cheap. But, hey, without a working stator, you just have a nice big green door stop.
You might check several of the Kawasaki vendors on the web for the best price.
Good luck.
Rick
