Bobber build

Hello fellow KZ enthusiasts. This is my first time on KZrider and my first post. I recently acquired a 1984 1100 ltd. I am planning on transforming it into a bobber. I have hundreds of ideas, but am having a tough beginning. I plan on changing the front end out to a -4" springer front end with a 21" front wheel. I cannot seem to find the neck size for my bike to make the correct purchase for the forks. I think it's a 1" neck, but I'm not sure. Also, I plan on putting spoke wheels on my bike. Does anybody know where to get spoke wheels for a shaft drive bike? Or alternatively, is there a belt drive conversion kit that anybody knows of? Lastly (for now), I want to simplify my wiring to the basics, i.e.- headlight(high/low), turns, running/brake light, and ignition. Does anybody have a simple wiring diagram or know where to get a cheap simple wiring harness? Thanks to all!!
