xroads,
Not to take anything away from the guys who have had good results from the PC, and now the excellent work Paul has given us, but there are those among us who have had very good results with the V11's factory tuning parameters. For me, it took a few "tune-ups" to get the results. If you can dope F-class you can tune your Guzzi.
Once you've mastered the factory settings and you are still not satisfied, there are these other options which many here will continue to help with.
(ie: when you're not grouping, the answer is probably not changing optics.)
