Remove every cover you can on the bike and locate all the rubber grommets...I can almost bet you are already missing one or two. Mine was even when brand new.
Easiest way to make sure you never lose another one is to attach a micro zip-tie around everyone you can...they don't have to be tight, they just have to be on...It guaranties you won't lose them anymore.
You will come across some which are just a push in button type...for these, remove and add some silicone to the hole and replace the grommet.
And while you have the covers off and some zip-ties...now is also a good time to hide a spare key in there somewhere with one.

If you have to ask if it's a good idea its probably not. Especially if you have to ask someone to hold your beer first.
I choose my own ride and destination and seek not your approval of either.
I have a thing for LED lights...oh, really? So, it won't come as a surprise to many that my tip is to add lighting and make it all LED. Possibly, the easiest and most important ones to add are flashing brake lights and preferably, the LED strobe type. There are several choices installed by various forum members. My favorites have been Federal Signal and HyperLites. These make you much more conspicuous to traffic coming from behind and could literally save your life.

Think about your physical condition, before buying the F6. If you can maneuver a 900 lb machine around safely, and back it up manually, in and out of tight spots, with or with out a passenger, then yes buy the bike. It is a great bike!
