Sounds more like it involves metal than electricity to me but then I'm not really too sure what either of those sound like. If that was what was happening would that be a fairly serious problem? Would it do it every time?

easy to check tho, pop the bottom fairing off, look in behind the bottom radiator at the round cylinder thingy(starter motor)...

There should be a bit of rubber covering the end of the wire going to it, BOTH nuts should be tight.

I had a look and nothing seemed out of place. I'm thinking its probably just a carbie issue that hopeful will keep quiet provided I remember to turn the fuel off as soon as I park it up.

Does the bike rattle at idle? if not then probably carbie, if it does then tis probably the starter clutch.
I would get it fixed asap, if you bend a crank(fuel dosnt compress like air does) it wont be cheep!

to check if the cylinders are flooded you pull the plugs out, make sure the kill switch is OFF and hit the starter button - fuel will piss out the spark plug holes if it is the case.

Except that most bikes won't wind off the starter button with the kill switch off - they're interlocked.
