It's possible it is running lean, but then, our impressions about such things are usually very subjective.
I had a similar impression with my CB...at certain RPM it seemed strained and the exhaust sounded raspy, especially in second gear (with stock exhaust). I considered a Power Commander, but then gave an O2 Sensor Eliminator a try. It smoothed out throttle response, the exhaust no longer sounded raspy, and the bike no longer shuts off fuel drastically when I roll off the throttle so there is no longer any abrupt engine braking in corners. Short of the hard data from a dyno run, this was the "subjective" cure for my bike (your results may vary)
For very little money, the O2 Sensor Eliminator Plug may be worth a try!
