Running without a battery?

Is this a terrible idea? I know Cycle X makes a kit so I can run without a battery. Just do kick start, etc.. Is this dumb? I'm making a bike for street use. I don't mind the fact of just using a kick start. Plus I think the retro idea is cool. But is this a really dumb idea?

That is the kit I am thinking of using..
 
Probably not very good bang for the buck.

What's the reasoning behind wanting to skip the battery?
 
Just get a capacitor no need to spend 500 bucks on a new charging system IMHO if yours works
 
but i do like their quote
"Best electrical product in the past 100 years.....by - Benjamin Franklin!!"
 
Well, this all stems from I want to compress my wiring harness.. What can I cut out/replace in order to make it smaller and more compact?
 
Re-do it
The factory harnesses are so redundant.
It only takes a few wires to run a bike.

Run new wire, from points to coils, power to coils, head, tail, blinkers, regulator and rectifier and call it good.
 
Ask and ye shall recieve

Yeah it really takes that shit honda did and makes it seem ridiculous doesnt it?
Thats like 10 wires to run the bike and the lights as opposed to 50 something in the stock harness
 
I agree. This makes it seem so simple that I'm actually contemplating a new harness for my CB450.
 
I've been toying with the idea of running just a capacitor to keep the look as clean as possible. Is it really as simple as replacing the battery with a capacitor? I have a cb360
 
I've used a capacitor to replace a bike battery, it worked well. Obviously kick start only and nothing will work while the bike isn't running but other than that I didn't notice a difference.
The cap I used was about 4" tall and 2" in diameter, was rated for 50V, can't remember the capacitance though.
Also be careful of the terminals :)

I'm definitely going to try that instead of running a bulky battery, I took out the starter anyway and was planning on running kick only. I wonder if a capacitor is like a battery where you have to match the amp-hours or if it can just handle more than the bike's charging system can put out and be fine.
 
a capacitor rated for about 40-50 volts and somewhere around 15000 to 30000 uF seems to work on these bikes
 
Something like this look ok?

Looks about right other than the minimum order quantity being 125 ;)
And the lead time being 83 days ???
 
HA i didnt even see that

much cheaper here http://www.digikey.com/product-detail/en/ECE-T1HP273FA/P10021-ND/258687
