I do not have any knowledge about dyno except its good for measure the relative power and air fuel ratio at the same time. Then change carbs to get best result.

Here is a video I took when one of the Dyno graphs in my earlier post above was done. Action Fours SS-1 cam
Nothing connected to bike except AF sensor sticked into the pipe. I decided to go for Carillo rods when standing beside with my phone and waiting for a rod smash thru the case. APE crank with Carillo rods made the engine to run much smoother!!

I also can't remember having anything connected to the bike except an A/F probe and a tube for my boost signal.
I feel you about the rods, image how I felt standing next to the turbo CB on the dyno, knowing that at that time it pinged on higer boost and revving it up to 9000rpm. Hahah!

But it holds up great! :)

I reminded myself while watching that I drive the bike like that very often! Not that often beyond 10.000 though, usually shift gear around 9000rpm.
