Hi I've just seen a boost bottle for sale on ebay for a rd350lc the add states that it increases throttle response and midrange power do they deal work?

Some have done a before and after dyno test and it lost power
Some say it helps if you have a stutter or flat spot

I have a boost bottle, and a while back someone on here kindly sent me a standard link tube, so I could see if there was any difference, nothing scientific, just how the bike felt with either .....
Felt better with. But that could be placebo, down to my particular set up, or even I just convinced myself because I like the way it looks
Not helping am I ....

Hi ,I have a 350lc with one on . I think it makes a difference . No scientific proof but there you go . Also I have made my own for my Tzr350 project ,again no proof but I think it helps .

You are, I think you are really saying no notable difference. |

You are, I think you are really saying no notable difference. As I recall back to back, bottle felt better pick up, but as said no way of backing that up with hard facts, as people say, seat of the pants dyno (hate that phrase) made me think bottle over tube, but other's have dyno tested and lost a HP or two. And to add to the mix, I run ypvs inlet rubbers, so the boost tube has wider inlets over the LC version, for what its worth |

Its been my experience that if the bike is standard they do do nothing other then look nice .Id fit one on that basis alone. However the more tuned the bike that better they are and if you run ypvs reed blocks with a hybrid bottle they are even better again. i have seen dynos adding 2 BHP all they the range once one was fitted on a tuned bike

I think so. I remember reading an article where someone was testing, in depth, the theory of boost bottles, and the best design was much, much bigger than the ones we fit. It wasn't actually attached to the rubbers themselves as it wouldn't fit ! I would fit one coz they look great, but wouldn't expect it to transform the performance, either way. Dusty  |

Yes a one with ypvs inlets have a bigger bole and the bigger the bottle the better |

I think boost bottles are a marmite object. I don't have experience of them myself as I've always thought them a waste of time and money and are butt ugly. Even if one did give me 2bhp I wouldn't fit one for that reason alone. so yea, marmite. Love it or hate it |

I hate Marmite  . Will that make a difference?  |

I had one on my tuned LC. Lost about 0.5hp compared to standard pipe, so it was removed.

yep, generally they lose power on a stockish engine, have some dyno graphs somewhere I think, I'll try and dig them out. They do work on bikes that rev really high e.g. RGV's, TZR's, Aprilia RS's etc
I have found that having "no" tube at all is actually better, but I am not getting into all that as it requires a few other tweaks to the carbs

I could not get the engine to work well and ended up putting the balance pipe back. |

I also removed the two boost bottles on my 3XV track bike, as the equivalent TZ (4DP) does not have them.
Boost bottles are probably best tested on a dyno to see if they make a measurable difference or not.
