The numbers for the Yosh piped 07 GSXR 1000 sound about right - depending on tuning. But the 750 sound low - very low. The dyno could just read a bit lower than average.
Why are the runs done in 6th gear? Did the dyno operator do this?
I generally use 5th (closest to 1:1 gearing) and the engine is loaded better. Notice that on your graph, the smoothing is at 5, and the engine is erratic at higher revs. Runs in 5th gear would be less erratic, even using the smoothing set on 2. You would only have a very slight loss due to gearing between 5th and 6th.
Thanks again for the chart. ;D
