The limits .....well, that woud be a lengthy and indepth conversation. Basically the vacuum operated slides cause a slow response time. The needle and jett combos even with the pilot jets actually do leave a lot of areas for compromise, not to mention that the slider causes turbulent flow. All making for limitations when trying to maximize out put potential.
Not exactly, the flow limitations would leave ya starving the bike when it comes to performance. We are looking to gain as much flow as possible.
I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.
