Wiring up an old bike; Need some help!

[deputy865]

So I recently picked up a 1974 Kawasaki KE100 2-stroke Enduro for some fun. I started tearing it down to clean it, repaint it and freshen it up and happened to think "Damn, this would make an AWESOME bobber/cafe bike". So I started the process of converting this old thing from a nasty old Enduro to a grungy street bike!

After a couple hundred clams, some paint and time.. I'm just about ready. One problem, this bike lacks any sort of wiring for... anything. It is a kick start, has no lights of any sort and the only working electrical thing on the bike is the kill switch. There seems to be some of the wiring harness left on it, but I'm not sure what it goes to. There isn't even a battery.

So my main question is, what all am I going to need to hook up a headlight, some blinkers, tail light and a license plate light? Am I going to need a battery and a bunch of stuff, or can I run this stuff just off of the bikes own power when it's running? The blinkers I can probably get away with using some small LED lights that are typically used for bicycles and are a "standalone" electronic that only basically requires a battery.. Same with the license plate light, I can just use something small and simple. But I'm not sure how I'm going to run the headlight and taillight. Main goal is to get it to pass an inspection so I can finally get a title for it and take it out for some bar hopping, bike/car meets and just to show it off. It's uncomfortable to drive this thing for more than 15 minutes, so whatever I do just needs to be basic.

Thanks for any help. I've never wired anything like this before, so I figured this would be a good and simple place to start.

*EDIT*

Decided to try to do this on my own. First time drawing up my own wiring diagram, so I hope my aim isn't too far off.

The stator, rectifier and voltage reg. are all optional. I need to check the status on my stator before I make this assessment. For now though, I'd be perfectly happy with these things running just off of the battery power as 1. This bike won't be driven far. 2. I can kick start it. 3. I hate riding at night. 4. I don't mind recharging the battery.

Orrr.. Can I do all of this WITHOUT the purchase of a battery?

I didn't draw in grounds because that would just clutter my little diagram. The idea is the least amount of wires as possible so I can hide them easier.

Each color on the diagram means a different wire.. If you see two of the same color connected, they are spliced in.

Turn Signals: I'll just get a pair that run off of an external battery. Something someone might put on a bicycle.

Headlight, license plate light, tail light, coil: I'd like to wire these to the coil switch so this way when the switch is in the "RUN" position, all of things are on at all times.

Horn: I'll just wire this up to a button, hide it somewhere and either splice it into a nearby wire or just run it right to the battery.

Brakes: Planned to run both brake wires and together the brake light itself into one switch and run that to the battery.

Any and all help is appreciated.

You might want to look into a battery eliminator. They're essentially an oversize capacitor which helps to smooth the output from the stator enough to run a headlight/tail light. Adding turn signals would be pushing it. They're also pretty damn small and cheap (~$40 on eBay).

Would I be able to run the tail light and license plate off of that too? Only reason I ask because those are the 3 things (headlight too) that will be on at ALL times. So basically, buy and wire that in instead of the battery... and wire the stator to that?

The turn signals will be a separate thing. I've seen a few pretty nice and bright LED turn signals that bicycle riders will throw on their bikes (for whatever reason) and they run off of a couple AA batteries or a 12v. That would work good enough for what I need.

The main reason for getting this street legal is just to get the title for it. So it just needs to pass the inspection from the officer. Most of the bikes I see around here that are bobbers or cafe bikes typically don't even have turn signals or a license plate light.. They are a little more lenient around here I suppose. Plus this is just a bar hopper bike, I won't be taking it far at all.
