Re: What's with the bottle
When the engine is on the exhaust stroke and blows the exhaust out the muffler, it also blowback some fuel/air mixture backwards threw the intake into the air filter.
When you have a boost bottle installed on the intake, the mixture would go up into the bottle to supercharge the next intake mixture.
I dont believe in them tho, mostly it just magically pockets your money, lol.
You could just send me the money and i'll tell you your bike goes faster, lol.
