It's a big twin and does vibrate a bit. It would seem that quite often the faults stem from summat shaking loose.
update- just checking over engine found central spark plug on cyl 1 half way out ! could well be the source of the click click click
ive lost several bits due to the vibes,a bolt out of my screen,one out of my numberplate,and i even lost a whole heel guard and both screws last week ffs.
i now constantly check and nip up all the screws and bolts i can get at.
