Mine is definitly not running too lean. I was thinking about getting a tuner so I could lean it out a bit. Its close, but just a tad on the rich side.

I'm wondering if the settings can be a bit random, even after the power up, from bike to bike depending on how there were set at the factory? Another good reason to get a tuner.
