hmm, seems like my manual (pdf, dowloaded from link avail here) had all the jets kawasaki said could be used (of course, they listed most as racing only).
the 1st part of the manual does not have part lists, you need to go to the latter half of the manual, and the exploded views there have the numbers.
also, several parts site on the web have exploded views (same ones I believe) and list part numbers for various jets.
others will chime in I am sure on other sources of jets
