Rattle between 6k and 8k rpm

[Caesar]

This its my first bike ('08 fz6) i got it used with 14k on it. I've had it about a month and just started to change gears at high rpms and noticed rattle noise that starts at 6k and stops around 8k.it sounds like its coming from the handle bars but I don't know if this is normal out what to check

It's the clutch lever. Next time you hear it put your hand on the lever see if the sound goes away.

My key used to do that until I lubed it up a little. Next time it does that hold the key to see if it stops

i have the same problem...not the clutch or the key

Checked all the bolts?

And how bad does a barrel have to be worn for the key to rattle? Must be able to start it with a screwdriver

ok I will check that next time... I am just glad that I'm not the only one Thanks for your replies

The harmonics of the engine tend to line up around 6k such that it vibrates the most around there, as you noticed. Since everything isn't perfectly rigid, that's where you're going to notice things vibrating the most - could be any of the things mentioned, or a connector, or bodywork...nothing to worry over.
