What is it supposed to do i've never really got a straight anwser but i have heard it gives you quicker throttle response, weather they actually work or not is another story.

 

Only use: To block your throttle cables away from your carbs.

I have one, its useless.

I feel them same did not notice any gain.[img]i/expressions/face-icon-small-smile.gif[/img]

 

The boost bottle is "supposed" too provide the 2 stroke engine with more initial air flow via an overall larger intake tract....more peppy with more low end power. This does not hold true....do you see anyone at a national level using a boost bottle? Nope.....if any gains were too be realized, then the racers scraping for every last bit of power would absolutely be using them.
