To get it working again I needed to get a new key made. First step was getting a blank key from the Kawasaki dealer. Man, they have some nice new motorcycles in there. Next, I had to remove the ignition and take it and the blank key to the locksmith. Then they just cut me a new one. So amazing.
I put it back in the bike, jumped it, and took it out for a test ride. I like riding motorcycles. Yeah. The starter is going bad though, so I'll have to take it in and get it checked out. There's a bunch of little things that need to get fixed with the bike, but once the starter is fixed I can ride it on a regular basis once again.
