Clearly only the biggest monkey in the world would compare across dynos or from bike to bike and a slightly less stupid monkey (no pun intended Billy ) would compare fractions of a hp over time.

The only way to truely know what an engine is doing is on the bench in a controlled enviroment, unfortunately this is very expensive, highly impractical and moreover bike engines do not live on benches nor do they sit stationary in still air.

Minor tweaks done there and then can certainly be seen, Steve and I undid and redid a couple of little thing to see the same fractions of hp come and go every time.
