I missed that, you are right Ken.
I've been reading about correction factors and had no idea there were so many versions. Most of the dyno charts I've been looking at don't specify what the CF is.
Or maybe I haven't looked in the right place.
A " Man Look" as my wife says.

One dyno operator explained that his Dyno could provide, uncorrected RWHP, or SAE j1349 corrections, or European DIN corrections, or STP corrections and a few more, all dependant on his choice. His STP correction used 18% as the mechanical loss factor.

Here's a photo of the bike and a quote from the owner.

“Ran great all season and won every race in the 500 period 1 class… It seems happy to rev to 9000 rpm.”
