Boost Bottle Industries NOS system

I installed nitrous on my 48cc through my boost bottle my needle I set second from bottom.So far so good have run a couple of bottles.I have only been giving the engine maybe 1 sec. or less of a shot It does pull out pretty nice ,I will pull head off soon to check out inside of engine.Will let every know If I have any problems or if I smoke the engine.
So why would anyone want a NOS button for their Motoredbike?
So they can cut their 0 to 20 time? :D
