Planning to add a 12V industrial capacitor to my bike instead of a battery?

I've got access to alot of big industrail power capacitors at about 10A carring 12v, theoretically, if i could directly connect it to the dynamo (generatior) inside the bikes electrical system and used a kick-start for the first charge, it (on the second kick) would discharge the capacitor to the entire electrical system and start the engine, obv iv thought of putting it on a seperate circuit for ignition only, has anyone ever heard of this being attempted?

any tips / warnings if it has been done before.
this would also mean that the bike would be lighter (no battery weight) quick and simple recharging aswell as not having to worry about leaving the lights on during the day
 
As long as your not planning on using the cap to energize an electric starter it will work just fine!

On my street legal dirt bike, I am running an electrolytic cap that is just under about half the size of a small bottle of water (I can't remember the farad rating on it). I just dropped it in the air filter box and wired it up with the stator.
I use the cap to remove any flickering of the head/tail/brake lights while at an idle, and to assist the stator in powering the horn. When the bike isn't running, it is only good for one quick blink of the turn signals though...

They even sell little kits at 4strokesonly.com to replace the battery with a small cap similar to the size that I am using.
 
I doubt that it would store and deliver enough electrical current to be of any use.Those caps by nature are nowhere close to the smallest battery in terms of energy storage. Nice thought though,look in to lithium ion batteries instead.
