I think that smokin was referring to the factory ECU flash being different for different parts of the world, not engine differences.
If it's not proprietary information, how did you acquire all of those? Have you already reflashed ECUs from each of those global market areas? If so, way to go Steve!
That is correct fartymarty ,all other specifications in the Genuine workshop manual show no difference in the mechanical aspect of the engine,i.e.,compression,valve timing,etc etc.
So that only leaves I guess exhaust restrictions,ECU programming in respect to the fuel type and octane I suspect.
One area I have noticed is that all the dyno results and there are a few show the Australian model in standard form putting out average of approx 138hp to the back wheel,and I understand that dynos give different readings but that is the average results.The some of the dyno machines are made in the USA.
So the data in the Genuine Kawasaki workshop difference in power output supports the dyno results in Australia versus the Steves USA dyno results
of 128.80hp at the back wheel?
