HOW IS THIS POSSIBLE?
i brought my bike to the dyno the other day to get a custom map and tuned. its a 2005 cbr 1000, 4k miles on it. yosh slip on, bmc filters, flapper mod. It made these numbers
1st run:
138.48 max power
71.49 max torque
After tune and map:
141.84 max power
72.35 max torque.
Run Conditions:
89.51 degrees F. 28.80 in-Hg. Humidity 26%. STD 1.06
Now to me, these numbers seem pretty ****ty, any reason why? I know it was hot that day, but still(and why would they do it if it messed up the numbers so much) and also they took the powdercoating off 1 of my pegs.
Just needed to vent and if anyone has any input or answer, please let me know

well for one thing
chrome is heavy and it takes a lot of hp to spin heavy wheels

and most people say (on the wheels), "the bigger the better!" pure bs.

Are these the straight numbers, before the correction factor is applied? If so, the corrected numberswould be146.8 and 150.4 - that's not too bad...

What do you mean by straight numbers. Those are the exact numbers that it had on the dyno sheet.

STD is the correction factor for the dyno, it's used to factor what the whp would be realistically. Now, there are several different correction standards and different dynos use different ones. Also, the calibration on a particular dyno has a large affect on the power outcome; who knows when the last time your tuner calibrated their machine.
Read up on correction factors here, it'll help you understand your results a little better:

No two dynos will give the same numbers on the same bike. Another thing is that their dyno may not be calibrated perfectly. At the shop I used to work at, I used my 06 1000 as the first bike we checked and we got numbers anywhere from 89 to 195 hp. It took a long time to calibrate the dyno and its always being fine tuned.
