I would but I just bought a used 2012 and so far I've spent almost $4,000 in suspension, roller lifters and a reflash kit for it,
As for your menu. Since you just got the bike I will say the menu will drive you crazy till you get used to it. Push it sideways and hold it there a few seconds. I'm at work now and can't look but you will get a screen that says menu. Push in to choose that then you should be able to scroll to diagnostics. The directions are in the owners manual. You need the code which is here somewhere and written at home but once again I don't have it with me.
Hang in there. More than once I have thought about pitching a Guzzi but they grow on you. I also have a Honda and Suzuki backup.
You can also try disconnecting the battery for several minutes to reset everything.
