...Ken, thanks for your comments. I'm just not sure what you mean by your saying "the unltimate dyno numbers are relative". Do you mean the best numbers are relative to your own bike and what you've done, or something else perhaps? ...



Staffo, allow me to expand. What I intended to say was that dyno figures can vary depending on the specific dyno used and other variables including but not limited to the operator, altitude, temperature & humidity. Theoretically the correction factors are supposed to adjust. I don't get to hung up on comparing runs between Bike 1 on Dyno A & Bike 2 on Dyno B. The same results on the same bike are not necessarily exactly repeatable from dyno to dyno. IMO the best measure of progress is against your own bike on the same dyno, & even at that the exact numbers are not necessarily repeatable. Therefore I prefer to watch the A/F ratio, & shape of the curves. That is in part why I said the ultimate numbers are relative & not absolute.

Regards,
Ken
