Sorry to pick up that old topic. I have just returned from the tuning shop. I went there because of some bad vibration, and to get the bike tuned.
The mechanic from the shop said, that in low and mid RPM she is far too lean, but in higher RPM way too rich. Probably that's the reason for the vibrations, that suddenly come and go. On the way back from the shop the engine was smooth, probably smoother than ever before. Throttle response is very good. I have a DNA-airfilter (similar to K&N), and I have lifted the air box lid a bit. Exhaust is standard, I won't afford another one here, they are very expensive for this bike here in Germany.
Results: about 90 hp on the rear, and 154 nm torque, which are about 113 ft-lb. I am very very happy that I took her to the shop
