So wait, you can actually tell the difference? Is there an actual improvement? I've heard so many negative things about boost bottles that I've shy'd away from them.Could be, but I don't think so. I make my own and can tell a difference with and without one.
First I match (exactly) cc cylinder to cc bottle.
Its not a boost bottle and its not a NOS rig, I have looked at it several times myself and it looks to me like it may be a valve on the one end that could be slightly opened to allow more air flow in from outside of carb, by doing this one could lean the air fuel mix and eliminate most of the four stroking that these engine do when carb is run with the stock size main jet which is to big and causes the engines to run way rich normally, I may not be correct in my thoughts on this being a valve that will allow you to let more air into the mix, but that is what it looks like to me and if so would actually work as long as to much air wasn't allowed in causing a serious lean condition and as long as the air coming through it was filtered.yea mabey but it dosnt really look like one of thoughs much ether
I'm having a hard time figuring this thing out too. I can't tell if the end is a filter or a knob. If it a filter, perhaps there is a diaphragm in the box to let air in at a predesignated ratio to vacuum. If its a knob, maybe you can control the "extra" air for yourself. It's a mysterious device at least. looks dangerous in the wrong wands.Its not a boost bottle and its not a NOS rig, I have looked at it several times myself and it looks to me like it may be a valve on the one end that could be slightly opened to allow more air flow in from outside of carb, by doing this one could lean the air fuel mix and eliminate most of the four stroking that these engine do when carb is run with the stock size main jet which is to big and causes the engines to run way rich normally, I may not be correct in my thoughts on this being a valve that will allow you to let more air into the mix, but that is what it looks like to me and if so would actually work as long as to much air wasn't allowed in causing a serious lean condition and as long as the air coming through it was filtered.
Those are my thoughts on the set up and it would do as advertised and "Boost" air intake by allowing more air into fuel mix, if not done right it would be a great way to cook an engine with a major lean run condition.... but like I said I'm not sure that is what the contraption is but it sure looks like thats what it may be.
It may not actually be adjustable but possible preset to just allow a slight air leak to give the "Boosted" power impression which is actually real when the mix is leaned just a tad, the correct fix for this condition would be to rejet the carb and not let in extra air from outside the carb unless you know for sure what your doing and did some testing to make sure you didn't create a serious lean run condition.

My thoughts exactly, it does look like a small filter on the one end, ihad not thought about there being a diaphram possibly, if so I dont see how it would work one a 2 stdoke like this which actually has a lot of blow back through the carb and intake, im gonna lean more toward aset orffice size that allows a little extra air into intake to lean mixture or a manual valve that can be used to adjust for allowing some extra air into the intake,
I just don't get why they would use such a big piece of plastic to stick an orifice in, other than adding to the magic. I guess a tiny drill bit and a marker wouldn't sell so well. Maybe we can market a fresh air boost jet for the intake. Even better, run the line to the handlebars, take finger off hose for turbo button.
