Clarify...What are you referring to w/ a "boost-bottle"?

I used to a boost bottle on my 2000 XC 700 and it worked well. I needed no jetting changes, but my jetting was slightly rich prior to using the boost bottle. It had no ill effects and seem to help low end stumble and slightly on the gas milage.

I've heard that the boost bottles really don't make that much difference, of course there's others that would disagree. If your the guy that had white plugs with the boost bottle and new silencer on........and now with just the boost bottle off your saying the plugs are now ok.......I'd just go with this set up.
