can anyone tell me?

 

not exactly sure, but it has somthing to do with regulating flow between two carbs.

 

Its supposed to keep the flow of fuel into each cylinder the same, some people like to run them and some people will block it off and supposedly have better fuel velocity, but Ive never heard of that being a fact. An aftermarket boost bottle is about the worst mod you could do, you will feel no change whatsoever.

 

1.) Holds paper on a desk well
2.) Can be used to shoot bottle rockets.
3.) When the holes are pluged it makes a great fishing bobber.
4.) Can be used as a water jug. IN desprate times.
5.) screws uneducated people outa $30.
6.) Can be made into a little bomb.
7.) Last but not least can be used as an instrament to preform the SHOCKER on your girl!!![img]i/expressions/face-icon-small-shocked.gif[/img]

So basicly nothing!!!!! But cost money, add bling, and can eventually wear out the boots that it goes into causeing them to crack giveing you an air leak.
