Curb Weight	0 Unknown at the moment.
Conversion Time	Over a year. I have been busy with night classes and this was my first conversion.
Conversion Cost	Around $4000 not counting the first batteries and motor I bought. They turned out to be too big.
Ok, so the controller was over-sized, I initially bought the wrong motor and batteries, and the build took an inordinately long time. So what? It works now. And I'm known as a crazy Doc Brown type by a lot of folks in my apartment complex. I couldn't be more thrilled. That said, the bike is a pretty mainstream design relative to the other Kawasaki's KZ's with AGM batteries you'll see here. The biggest challenges for me were the build process and the wiring diagrams. You think you know where a particular hole or component should go....but no, it really has to be 1/8" to the right, or in a completely different location! Oh well, c'est la vie.
