CIP, here are some charts from my dyno runs in May 2014 (stock ECU).

I did a baseline run totally stock and returned a few days later with a full Yoshi exhaust and TSR air funnel installed. That day we did several runs:
Run #1: Yoshi exhaust, TSR air funnel, 02 sensor bypassed
Run #2: Yoshi exhaust, stock air intake, 02 sensor connected
Run #3: Yoshi exhaust, stock air intake, 02 sensor bypassed

The first, stock, baseline run was done in 4th gear, the second day runs were done in 3rd gear to keep the rear wheel speed limiter from cutting in before the RPM limiter.

I cleaned up the charts slightly as the operator placed some notations on the curves and I edited out the 1/4 and 1/2 throttle run curves.

Since press reports on max HP vary by quite a bit, it's not surprising that my charts are lower than others posted here. My dyno operator was very tolerant of me making mechanical changes to the bike while it was sitting in his rig, but the lack of dramatic differences was surprising. I keep hoping someone will do something similar and "disprove" my results!
