Ive just had a bit of a vision of an easy to make boost chamber, I haven't made or tested it yet but i thought i'd share now anyway. I have recently bought and fitted a 49cc engine to my bike, my initial thinking was to cut down my intake manifold before the elbow, I tryed this but it didn't really do what i was hoping for, the engine seems to rev out easier down hills etc, but feels like it has lost some chugging power.
Since then i have been reading up on boost bottles and boost chambers a little bit, i have read that your bottle should be the size of your engine capacity. That sound too neat for me, and doesn't take into account flexibility of your bottle/s or hose if used. i want one i can tune in myself and play with, anyway heres my plan. Im getting a manifold made up that with holes along it that i will insert a number of threaded CO2 canisters(from tire inflaters), that i will bore out the holes on. I'm thinking a nice v8 stack, but i'll see. Then i can remove them and plug the holes to tune it in.(or add more if bigger seems better).
I'm waiting on a new manifold to arrive after butchering the last 1, so wont get to try this for a while. I will post my results when i do. If anyone wants to try it before me you are welcome to. I hope i explained it well enough. If not ask. I am not a mechanic, this is just an idea i had and thought i'd share.TRY AT OWN RISK. Please post any results, or comments

I've played with the boost bottles made an adjustable one and different sizes and shapes etc. My opinion is don't waste your time get a tuned pipe and dremel your ports,match up the gaskets etc.
