Hello all,
My need for speed out weighs the conservative side in me. Seems like what ever I drive or ride always needs more power. I have ridden my bike with these mods ( and I ride it hard - over 30 mph everywhere ) and I have 900 miles on it with no problems. In the back of my mind though, if the motor were to seize at that speed it wouldn't be a good day I'm sure. I have a 36 tooth sprocket coming soon so here comes 40 mph. ha ha

If they work so well, why do no manufacturer's use them? | Hello Bikeguy Joe,
Here is a link to Dyno results of the boost bottle working. I can testify that on my bike when I didn't have it and now that I do, the bike is definitely more powerful. Here is the link to the dyno results: Page Title

Here is a site with visual references and a picture showing the flow out of the boost bottle to the cyclinder. Yamaha did this as well as some other manufactuer's. It is interesting to see how others have plumbed in the boost bottle and that they even made the bottles from square plastic shapes. ------> click here: Boost Bottle
.....Thanks, quarkdude

Thanks, how about some charts from an independant source?
The link to the site with visual references didn't come through.
Are there any manufacturers that use them now? What about in racing applications?

My need for speed is satisfied in several ways, but the motorized bicycle is my solitude ride, not my racing machine.

Folks, I'm perhaps one of the biggest skeptics out there. Perhaps its my engineering degree, years as a military test pilot, and 20+ years of tinkering with electronics and mechanical items.
I will install a boost bottle on my bike next week. I know that my engine has a top speed of 23mph up a very steep hill at my house which is at 7,000 feet altitude. If anyone will notice a difference in power, it will be me. I will also measure time and distance to top speed from the same starting point | | Thread Tools | | | | Display Modes |  Linear Mode |
