Impressive! And it got shut down before it was done, it's still in a steep climb.

If my conversion is correct, that's 124.5hp.

Conversion is the same am SAE ( 95/1/CE). These are 126 Hp at the rear wheel.

This Dyno machine has a Range to configure (when it start to register and when ends to register)
It was set by the operator at 1700 Rpm to 6500 rpm.

So it ends at 6500. This run was the 2nd and the bike was still good temp .
Then it started to be too hot.

SO when I told him to put the limit at 7000 the bike was a bit too hot.
But then (in addition) I discovered that the Dyna 2000 file I installed was with a 6600 RPM LIMIT. (I was sure it was 7000)

So the next few session are with the rev limiter cutting the power at 6600.

At the end we tried to "cure" that little dip of torque at around 5000 rpm.
We run removing the Hammer Sledge KN oval filter (Backing plate only installed).

We smoothed the curve but the bike was no more cool and the 6600 CUT, kept the HP under 130.

You might also check to see if your Dyna 2000 has a soft or hard cut and if a soft cut, what specs they use.

I know this is nit-picking, but I believe aswracing is correct.

CV X .9863 = Hp
126.27 X .9863 = 124.54 horsepower.

Either way, a good number. Well done.

Sincerely I don't know.
In Europe we use HP like CV and CV like HP , the difference is minimal.
What I know is that the operator (the owner of the Dynometer) has to pull the cluch after the computer tell to do it. He stays whit the clutch lever pulled untill the bike returns to about 1500 rpm.

What I've seen "live" on the screen is a 129.xx CV during a run (the third one) , then, instead, I have NO sheets with 129.xx CV , but the max i see is 126.

It's a NO-problem thing . The bike loose traction shiftinging from 1 to 2nd , from 2nd to 3rd and from 3rd to 4Th too ...

I don't know the existence of this feature.
On the software I can put the rev limiter level but not a Soft or Hard cut strategy.
