It is only my first month with this bike, so maybe it is perfectly normal. Yesterday to give some sort of a cleaning. What caught my attention was that some parts seem quite loose and can "wobble" quite a bit. Do they all do this? Is this because of all the rubber mounts?
Can only comment on this from point of view of my GT - but parts are the same.
Tail light - yes it wobbles around a lot
Instrument cluster - yes wobbles
Exhaust - doesn't wobble too much but yes, it does move around a bit.
As you say, due to the rubber mounts on all of them.
More than these can come a little loose or worse. I make a pass around my ('12) every 500 miles (programmed reminder) tightening the fasteners for all the body work, turn signal lights, the bolt holding the speed meter (rear wheel, down low, left side; shop once forgot to tighten it) and anything else that isn't "industrial strength" fastened including the the shield on the stock exhaust. I often find quarter turns needed. Been on several group rides where "hung" bags fell off bikes, exhaust pipe was hanging at start, etc. (None of these were F800R's.)
