I think your best bet would be to take the locks to a Locksmith in your area and let them have a look at them and see if they can make up a set of keys.
There is a Locksmith that has a web site to order keys as well that you could try, I don't know the web address, but a search should turn up something.
A Kawasaki dealer may be able to help as well.
Your numbers are still a puzzle though. I have never seen stick on code #s. They have always been stamped into the lock. Plus your #s do not fit into any of the code series.
